MI-L Registering *lots* of raster maps

[Tim Smith]

Hi List,

I am new to mapinfo and I've just managed to register a raster image and
create a table for it.

I have got lots of raster 'tiles' that make up an entire map. Problem
is, I have over a million of them!
Obviously I can't manually 'register' all of these maps - I'd be doing
it for the rest of my life!
What's the best way to do this? If I wrote a tool to automatically
create the tables, can mapinfo dynamically choose which tables to
display? - because my geoset isn't going to be very happy with 1,000,000
tables.

Could I create one table with lots of raster images in it?

Our old mapping system dynamically loaded the maps it needed to display
based on the filename. The filename contains the easting and northing of
the bottom left corner of the image.

As far as I know mapinfo can't do this - you need three reference points
per image. Besides - I still need to register *all* of the maps.

I can't 'stitch' them together. This is too time consuming as we have
several sets of a million tiles!

I'm thinking that I might need to dynamically create a table and load it
whenever the map moves or is zoomed. I'd use MapX to display the maps
and I can then do dynamic table manipulation.

Damn this is tricky.

Thanks for any help listers.

Kind regards

Tim Smith

Tony,

Not specifically OSGB - but that is one of my sets.
File names are like
46250975.L00
The first four digits are the easting in 100s of meters and the second
four digits are the northing in 100s of meters
i.e.
462500E 97500N
The tiles are of a fixed size.

Kind regards

Tim

Are you in OSGB and , if so, do your maps have titles like st1234 and do
they have a fixed tile size. If so I can adapt an mbx we use here for
registering raster maps

[Tim Smith]

Hi Ian,
 
Thanks for your help.
 
I probably have enough information from everyones help today to create
my own tabled automatically.
I can then merge some maps into layers.
 
But as you say there will probably be issues with the limit of files or
size of bitmap data.
 
This is still my final problem.
 
Once I've created my million or so tables that I've automatically
created, I now need to dynamically load the ones I need.
 
It's going to be an interesing one to solve.
 
Kind regards

Tim, 

You need to loop through all of your files and create a .tab for each
one. The .tab can be created as follows (in MapBasic) 



open file tablename for output as #1 filetype "MIta" 
print #1, "!table" 
print #1, "!version 300" 
print #1, "!charset WindowsLatin1" 
print #1 
print #1, "Definition Table" 
print #1, "  File """ + filename + """" 
print #1, "  Type ""RASTER"" " 
print #1, "  (" + tle + "," + tln + ") (0,0) Label ""TopLeft"", " 
print #1, "  (" + tre + "," + trn + ") (35000,0) Label""TopRight"", " 
print #1, "  (" + ble + "," + bln + ") (0,35000) Label""BottomLeft"",  "

print #1, "  (" + bre + "," + brn + ") (35000,35000)
Label""BottomRight"" " 
print #1, "  CoordSys Earth Projection  8, 79,""m"", -2, 49,
0.9996012717, 40, -10 Units ""m"" " 

close file #1 

You will need to look in your first tab file for the correct values for
the coords i.e. (0,35000) etc but as all of your areas are square is
should be easy. 

I have used a Seamless table on about 100 tables of aerial photos and it
works really well (I don't know what the limits are)

Hope this helps,

MI-L Raster map distortion/flicker

[Tim Smith]

Hi List,

My raster map 'flickers' when I move map features around that are on
another layer.

The flicker occurs around where the feature moved from, almost as though
the map is being redrawn back where the feature was, but not correctly.

It seems to be only when the zoom level is such that the pixels are
'compressed', i.e. I'm zoomed out quite a way.
Has anyone seen this before or anyone know how to fix it?

Thanks for any help.

Kind regards

Tim Smith

RE: MI-L Raster map distortion/flicker

[Tim Smith]

Hi Stephen,

I tried your suggestion but alas, it's still a problem - must be
MapInfo.
Looks like a rounding error in the mapinfo display code that decides
where to redraw the map areas that have changed. The error causes the
area to be replaced one pixel out of place, hence you get a sort of
'jiggling' effect which is quite offputting.
I am using MapX to dynamically create features on a layer. The features'
positions change rapidly, so the effect is very noticable.

Cheers

Tim

Hi Tim,

Something that I've found can help with this sort of problem
is to turn down "hardware acceleration" on your PC graphics card - This
generally sorts out minor graphics problems without noticably affecting
performance.

This will usually be under "settings  - Control Panel - Display -
Advanced
-- Troubleshooting"
Or something similar, depending on Windows version and PC settings . I
generally set Hardware acceleration somewhere between 25% and 50%, using
the slider bar.

GML stands for Geographic Markup Language. It's actually a geographic
implementation of the XML (Extensible Markup Language) format. And XML
is simply a way to structure information using bracketed tags in a plain
text format. You can learn all about it at http://www.w3.org/XML/.

XML is coming on strong, too. You'll be seeing a lot more of it in the 
future.

MI-L Large raster maps

[Tim Smith]

Hi List,

This goes back to a question I asked before, but just want to clear a
few things up.

I have loads of raster data (20GB). Can MapInfo handle a 20GB raster
image? If not, could it handle, say, 40 500Mb files?
I'm still trying to find out some information about efficient methods of
using lots of raster data with MapInfo.

RE: MI-L Large raster maps

[Tim Smith]

Thanks people who suggested the ecw compression.
I'm trying it now. I got the PSP plugin too.
Is there anyway I can append bitmaps to the ecw image one-by-one?
Problem is - The free ecw compressor only supports 24-bit bitmaps, so if
I've got 1,000,000 500x500 pixel tiles that's going to be 733k x
1,000,000 which is a 733Gb image I don't have that kind of storage.
At present I use RLE bitmaps and is compresses to about 20GB - far more
manageable.

Cheers

Tim

Nowadays we use ecw format to open huge files. You can compress images

RE: MI-L GML to MapInfo

[Tim Smith]

Hi Bob,

I looked at MapGml - it does translate the different layers well.
I'm probably going to be using the topographical layers.

I have to confess that I'm really new to MapInfo (due to go on a basic MapInfo course 
next month)
and I'm new to changing the look of the maps.

How can I change the look of the layers to be like the example shown on the OS site...

http://www.ordnancesurvey.co.uk/oswebsite/products/osmastermap/topography/

I can't get the road to be 'solid' - it's just lines.

Kind regards

Tim

Hi Tim

When MapInfo wrote their import for Version 7.5 they only had Topology data 
from OS.

As OS release new layers to MasterMap we introduce updates to our MapGML 
Translators. MapGML will currently translate Topology, Addresses and ITN. Also 
it takes the compressed GZ in batch which is faster than uncompressing to 
GML.The whole of Hampshire takes 80 seconds ( yes seconds ) to translate. We 
also include some post processes which can take relational table information 
back to flat file if you want this.

We anticipate a market for ITN only so have just introduced MapITN for £395. 
This translates ITN as per MapGML but ignores addresses and topology. The full 
MapGML is a bit more expensive at £750. We are committed to providing all new 
MasterMap layers free of charge to MapGML users on Maintenance ( £225 per 
annum ).

I appreciate users would like free translators but there is quite a bit of work 
involved with keeping the software up to date. For example we along with other 
software developers have been with Ordnance Survey today looking at proposed 
improvements to MasterMap delivery. When you consider how much you pay for the 
data itself I believe having up to date software is worth the small additional 
cost.


If you are interested in MapITN or MapGML we have an evaluation version. This 
leaves small "holes" in the tables but will give you a good idea of what output 
looks like. We are also very open to users ideas for continued development of 
translators.For example ITN contains routing information and we are keen to 
include tables to suit all users needs in the routing market as well as those 
who just need to manage assets.

If you just want one translation we willingly carry this out of free of charge -  
without the holes !! Just send us your data.

We can be contacted on 01847 622569 or by email. Alternatively come along to 
the next MapInfo User Group at Blackburn on the 22nd July - we have a stand 
there.

I apologise to listers for the plug, but Tim did seem to be looking for a 
solution and I think the above fits the Thoen! - sorry Bill!

MI-L loading multiple tab files

[Tim Smith]

Hi list,

I was trying to use the seamless layer manager (SEAMMGR.MBX) and can't
quite get it to do 'batch' merge my tables.
The instructions tell you to "open the tables you want to include in the
seamless map sheet and display them in a map window".
I opened multiple tab files and it has seemed to have grouped them two
per window. Why is this? Why does it not either load them all into the
same window or individually? See the image from the link below.

http://www.ezblitz.com/pics/mapinfo.jpg


Anyhow, when I go to create a seamless layer, it only merges the tables
that are loaded in the currently 'focussed' window on the screen, i.e. I
can only merge two at a time. Is there anyway to get the seamless
manager to merge all tables that are open? Or, how can I load all tables
into one window?

Is there any other way of batch merging tables.

All my tables have exactly the same format so there should be no
problems there.

Kind regards to the list

Tim Smith

What you need to do is right click a mapper window goto Layer control

make you layer. It's a feature that MI opens loads of windows. Don't

"open the tables you want to include in the seamless map sheet and
display them in a map window". I opened multiple tab files and it has
seemed to have grouped them two per window. Why is this? Why does it not
either load them all into the same window or individually? See the image
from the link below.

http://www.ezblitz.com/pics/mapinfo.jpg


Anyhow, when I go to create a seamless layer, it only merges the tables
that are loaded in the currently 'focussed' window on the screen, i.e. I
can only merge two at a time. Is there anyway to get the seamless
manager to merge all tables that are open? Or, how can I load all tables
into one window?

Is there any other way of batch merging tables.

All my tables have exactly the same format so there should be no
problems there.

Kind regards to the list

MI-L WOR 2 Geoset

[Tim Smith]

Hi List,

I have a .wor and I would like to create a geoset that looks the same.
When I go to create the geoset I can't load a wor file, only tab files.
This means I have to manually change the layer appearance to look like
the wor.

Any ideas how to create a geoset from a wor file?

Cheers

RE: MI-L OT - Windows Programming Philosophy

'using private profiles (those *.ini files) is no longer in fashion'

I've never used them - I've been programming Windows since 1996 and have
always used the registry, but I guess that's because I've never known
anything different.
I admit that when you open regedit it does look a mess, but it's ok once
you know how to use it. If you find it easier to use ini files for
configuration, then there's something wrong in your software design, or
so say Microsoft.
I use install shield to set up the registry for my software.

MI-L Australian maps

[Tim Smith]

Good-day listers,
 
Where's the best place to get street-level Mapinfo maps of Australia?
 
We are a UK company who, until recently taking on an Australian client,
sold solely to the European market.
We currently use Tensing SKS for our Euro maps. Our Australian client
needs to manage their own MapInfo maps which they will use in our
software.
They need full Australia coverage at street-level.
Would probably be best to use an Australian supplier, but that's not
essential.
 
Cheers
 
Tim

RE: MI-L Australian maps

[Tim Smith]

Hello Simon,

Thankyou very much for spending some time in ansering my question. I
think this will help me a lot.

Our customer is visiting next week and I was hoping to find, perhaps,
some free sample data/screenshots of examples of street-level data being
used in MapInfo. The project does not start until next year, but we need
to sort out what maps they like first as the software we write will be
dynamically interacting with the map data.

Thanks again.

Kind regards

Tim Smith

Hi Tim,

I've recently moved over to Australia, from Experian in England, where I
consulted on all spatial aspects of their MicroMarketer product. One of
my key tasks over here is to develop the roads data from the Public
Sector Mapping Agency (PSMA), who are the most comprehensive suppliers
of nationwide Australian roads data. 

I've done some research into finding the optimum roads data available
and the PSMA seem to come out on top. Their street level data is superb
and as detailed as anything you would find in an O/S Meridian2 data set.
They even map rear-access alleyways, where they still exist.

They have really improved their output in the last update, so much so
that I am recommending we remain licensing their data for the time
being. The only problem with their data is that it is contributed by
each State individually and compiled by the PSMA. Some of the road
classifications can differ from State to State which can display rather
interestingly along the borders.

There is an alternative data set supplied by Sensis (www.sensis.com.au).
They claim to have a national scale road data set (i.e. not appended by
State). I have only seen individual samples from each State and not a
national scale layer so I cannot comment on the quality of this. If you
require national level data from Sensis, I think they will charge for
the work involved in putting a sample together.

Let me know if you want any further information about this. We are in a
position where we could sell on our value added roads, but it is not
something that we normally do.

Hope this helps

MI-L MapX run-time installation

[Tim Smith]

Hi List,
I have a MapX question that I have asked MapInfo about, but I thought I
might get a good answer here earlier...


Hi,
 
I want to distribute our MapX application. I have read the user manual
and it indicates that there are two ways to licence the run-time
libraries.
The easy way is to install MapX from the MapX install CD, the other is
to include all the dlls etc. in my own installer.
I want to do the easy way.
 
How do I supply our customers with the MapX install CD?
 
Can I copy our CD and give it to our customers and then purchase
licenses?
Or does MapInfo supply a CD with each run-time license purchased?
 
Is there a separate run-time installer CD than the main MapX development
CD?
 
Thanks for any help with this.
 
Kind regards

Tim,

What are you using to import the gml to MapInfo? Most third party
translators use the style information in the cartographictext layer to
make the text appear as expected.  There are several attributes that
relate to the text styling:

 3
1
3.000 0


The gml above shows the elements you can use to display the text.  The
attributes DescriptiveGroup and DescriptiveTerm allow you to set the
font and colour properties for your text object.  There is a standard
style guide available for download from the Ordnance Survey website that
shows what colours and fonts can be used for text.

As to doing it inside MapInfo I suspect you will need to create some
mapbasic to process each text item according to the above attributes.
Correct application of the height value will mean that text won't
overlap.

Subject: MI-L Data Extraction from a GeoTiff


I have a 1.7 Gb (yes, gigabyte!) GeoTIFF image that I open in MapInfo.
The image is an airphoto mosaic of salinity that contains areas that
have been classified as old salinity (red pixels), recent salinity
(orange pixels) and areas for possible future salinity problems (purple
pixels), in addition to the background airphoto.

How can I convert this image to meaningful MapInfo polygons (my three
categories I have noted above) as I then plan to use them in an "Erase"
operation to highlight only favourable areas?

Pointers to freeware are especially appreciated, but will also consider
commercial products.

Thanks in advance,

Bill

MI-L Route planning

[Tim Smith]

Hi list,
 
Bit of a strange one.
 
Is there any way I can calculate a route by road using MapX?
Perhaps there is a C++ library that can be used with MapX that uses
route-planning map data.
My application needs to dynamically calculate the route and highlight it
on the map.
 
Hmm..
 
 
Kind regards
 
Tim

RE: MI-L MapX Question

[Tim Smith]

Neil,

Hope this helps

Kind regards

Tim 



Differences between MapX 4.51 and MapX 5.0

In MapX 4.51 when a new table was created using a LayerInfo object of
type
miLayerInfoTypeNewTable, the coordinate system used to create the new
table was the map's current
numeric coordinate system. In MapX 5.0 the map's numeric coordinate
system is used only if you do not
specify a features collection as the "Features" LayerInfo parameter. If
you do specify a features collection
the coordinate system of the layer from which the features collection
was built is used as the new table's
coordinate system.

Bugs Fixed in MapX 5.0

23985
Cannot use miAggregationCount on a string column. The Fields.Add method
allows the user to specify
how values in the resulting Field will be aggregated. In MapX 4.51 a
user could use miAggregationCount
on a string column. This functionality did not work in MapX 5.02.19 but
is fixed in this release.

23881
MapX is not reading the "LABEL\PARALLEL" = "TRUE" key in some geosets.
This worked in MapX
4.51 but was not working properly in MapX 5.02.19. MapX misinterprets
the value of the key. The labels
display opposite of the way that they should, e.g., straight labels
display as curved, and curved labels
display as straight. This problem has been corrected.

23853
There is a new section in the MapX help entitled "MapX Field Naming
Conventions". The sections
explains what characters can and cannot be used when naming a MapX Field
object. It also explains
when these rules are enforced e.g., when an error is thrown when an
invalid Field name is used.

23840
SnapToNode now works properly with the AddFeature tools.

23781, 15291
Geosets with multiple raster layers now center properly when opened.

23745
Performance (speed) for panning, zooming and other map operations on
seamless raster layers has been
improved.

23492, 23493, 23468
Memory leaks in the OCI, DAO and XML datasets have been fixed.

23450
he Geodictionary Manager now displays the geodictionary path when you
lon on as a restricted user.
The new behavior in MapX 5.0 is described below.
GeoDictionary under a restricted user:
The geodictionary will allow restricted users to see the geodictionary
file path and registered files. No
write access to registry and geodictionary file and path is given by
default.
To allow restricted users to change the geodictionary file path and/or
additional search paths, registry
access to the \HKEY_LOCAL_MACHINE\Software\MapInfo\MapX\5.0 key must to
be granted
to that user via regedit.
To allow restricted users to register tab files to the geodictionary
file path, access has to be given to write
to that file and path in addition to the registry access.
GeosetManager under a restricted user:
Make a new dword key "NoGeosetToolsMenu" key under
\HKEY_LOCAL_MACHINE\Software\MapInfo\MapX\5.0.
The warning (not an error) that comes up "unable to update the registry"
has nothing to do with MapX. It
is an error that occurs in MFC when the application attempts to register
itself as a server. It fails under
restricted use. This is harmless.

23033
The redraw issue of multiple extraneous lines appearing on the map at
certain zoom levels has been
corrected.

23029, 20599
The redraw problems caused by panning the map when there is an object in
the animation layer have been
corrected.

22475
Setting LabelProperties.LabelPartialObjects to true now produces the
expected result
whenLabelProperties.LabelAlong is set to miLabelAlongMultiSegment.

21259
MapX now creates valid geometries when editing objects in Oracle
Spatial.

11800
You can now bind data (create a dataset) on tables on read-only media,
and you can perform Layer.Search
on such tables.

RE: MI-L Coverting multiple OS MasterMap GML 'chunks' to Tab format

[Tim Smith]

Paul,

I'm dealing with large amounts of Mastermap data too.
You can only import the files one-by-one using the converter supplied in
MapInfo 7.5.
You could be a masochist and do this and then create a seamless layer,
but then you can't process a seamless layer table!
I would be interested in anyone who may have written a MapBasic program
to automate this.

I tried MapGML (see http://www.mapsbydesign.co.uk/mastermap.html)
This works well and can converts straight from the .gz files. You can
change the convertion script to split the layers how you want.
There is a demo version available on the site.

Ordnance Survey recommend MapGML for MapInfo...
http://www.ordnancesurvey.co.uk/oswebsite/products/osmastermap/systems/

Keep me updated with what you find & I'll do likewise.

Cheers

Tim

I am using MapInfo Pro 7.5 and am looking to create a OS MasterMap
datasets in Tab format.

I have requested the GML data from OS but this has been supplied in 5km
by 5km 'chunks' (or tiles). In the past I have only imported individual
GML files to Tab by using the 'Table > Import...' option, but now I have
75 GML 'chunk' files which need merging into 1 Tab file (ideally without
causing overlaps/duplication).

Does anyone know how MapInfo deals with multiple GML 'chunk' files?

Hi,

Have a look at MapX. You can write your own (Visual Basic, C++ and

May or may not be what you want.

Hello,

I am a total newcomer to MapInfo 7.0 but have programmed in VB / C++ /
Lisp etc on other 
platforms. I have just got it installed and would like to know what are
the available development 
platforms in MapInfo 7.0.

I understand that the native development tool is MapBasic. My questions
are:

1. Is Mapbasic the only platform for Mapinfo 7.0? If yes, how do I get
started with it? Where is 
the online programmers documentation etc?

2. Is VB or VBA a possible programming tool?

Let me know some answers so I can get started with your kind help.

Regards
Rakesh

Ah, the old "Drunken Salesman" problem!

But where in the world is Trægården, Denmark anyway? Since there's no other 
place near Denmark, I'm going to guess that (10E, 56N) is close enough for this 
problem. Santa can just dump the presents out of the sleigh from 10,000 meters 
and the scatter should distribute them well enough, don't you think?

RE: MI-L : Speed processing issues

[Tim Smith]

I agree with Warren. Make sure your PC is not using swap files.
I do processing on huge amounts of data (1,000,000s of files and >40GB
of data).
My PC had only 512MB and was heavily swapping memory to the hard disk. I
have optimised my algorithms to use less than 1GB and have upgraded to
1GB of RAM. This increased processing ten-fold.

Hello Bill,

I do processing that takes days even on a high performance machine so I
know how you feel. Your processing time will be influenced by a number
of factors. Let's put the software ones aside for now as you were asking
about hardware.

512Mb is a "little light" these days but it depends on what your process
does. Do a Ctrl-Alt-Del and select Task Manager > Performance. You can
see here what your system is consuming memory wise. As long as you have
physical memory available and do not dip into the virtual pool, then
your current memory is fine.

Your processing will help quite a bit if there is some number crunching
going on but I would suggest that you're fine with 2.4GHz. Unless you
are running other things too, you probably would not notice much
difference with additional processors either.

My favourite area for update is disks and I'm a huge fan of SCSI drives.
They are so much faster than EIDE and will help cut through your data
very quickly. I have no experience with SATA but am told they're very
good too.

The cheapest option is to look at your code, over and over again. There
is nearly always a potential change in there which looks so small, but
over the processing iterations can chip hours out of run times. It's a
shame that MB never had an execution profiler to help with such things.

I am doing erase, combine and disaggregate operations on 1.3 Gb files,
and needless to say, the processing times are ridiculous ... hours and
hours .. ad infinitum!

I have implemented the idea of using the MapBasic window and choosing to
bypass transaction files by the process:

set table YourTableName fastedit on undo off

Aside from the impractical option of purchasing a Sun Sparc station,
would it help if I was to increase my RAM or even processor speed? I am
currently running on a 2.4 GHz Pentium 4 with 512 Mb RAM. Or should I
maybe consider doing these operations in another product that imports
MID/MIF files?

Thanks again,

MI-L Integrating MapInfo Pro

I don't have mapbasic and I can't find an evaluation on the MI site.

What is the licensing situation when creating an application like this?
Does each application that is distributed require a full mapinfo

Hi Tim,

MapBasic includes lots of samples on how to do this (integrated
mapping). Of course these samples should have been supplied with MapInfo
itself since they do not require mapbasic.

There are also 2 mfc based samples.

Hi list,

I currently use MapX and noticed some interesting statements on the
MapBasic product page on the MI web site (see below). Does this mean
that I can create a window in my Visual C++ application (as I do with
MapX) and display maps and control them using the same functions as
MapBasic, but via OLE? How does this work?

MI-L MapXtreme and C++

[Tim Smith]

So, thanks for help on the integrating MapInfo front.
Looks like we're gonna have to start using MapXtreme2004 for our future
projects.

Question(s).

As I have mentioned, we currently use MapX. Problem is, MapX is not
supported in two years, so we need to move to a new product.
MapXtreme2004 using VC.NET is the obvious choice, but I'm concerned
(apart from having no .NET experience) about performance and the effort
required to port our MapX system.
We happily run our MapX system on an embedded 133MHz, 32MB pentium
system with Win98. Unfortunately the hardware can't change, although we
can go to Win2K or XP. What sort of performance issues are going to
arise from running MapXtreme applications on such a dated system? Can it
run at all? Are there alternatives to MapXtreme?

Ta kindly.

Tim

RE: MI-L MapXtreme and C++

[Tim Smith]

Thanks Uffe,

We have a new system which replaces the old 133MHz system which could
run MapXtreme (1GHz, 256MB), we just want to support the old system, but
it's looking more like this is not possible.

I guess we have no choice but to move up to MapXtreme (and forget
supporting the old system), and given the amount of distribution we
need, the cost of MapInfo licenses for integrated mapping is just not
viable.

Are MapXtreme run-time licenses the same price as MapX?

Cheers

Tim

Hi Tim,

Integrated mapping requires, that MapInfo is installed on the computer,
so it isn't cheaper than using mapX, but offers other possiblities.
MapInfo Runtime should also be an option.

If you are truly locked into that kind of hardware, .NET is not an
option. With 32 MB RAM I don't even think W2K or XP is an option. And
Win98 isn't supported by MS either !

Your best bet is either sticking with mapX or finding some other 3rd
party mapping component that fulfills your mapping needs. There are many
available - also quite a few that will read TAB files: Cartovcl,
tatukgis, geoobjects and possibly more. If you require editing TAB
files, it could be harder.

Kind regards

MI-L Registered rater map limit

[Tim Smith]

Hi List,

Thanks for your help with my questions over the last few days.
But; another question :)

What is the limit of the amount of raster map 'tiles' that I can
register and then merge into a seamless table?

I have 1,240,000 raster map tiles and have written a tool to register
these automatically, so I have 1,240,000 tab files (haven't got a tool
for creating a seamless layer from these yet).

I can load these map tiles into the current mapper about 500 at a time
(bug in MapInfo means that if you  attempt to simultaneously load many
more than this it just ignores you). I have successfully loaded about
2000 raster tab files in this way and have created a seamless layer.

What are the implications if I loaded 1 million tiles? Can mapinfo's
database handle this?
If I could automate the creation of the seamless layer table, i.e. not
attempt to load them into MapInfo, could I use them in a MapX
application (hoping that it is intelligent enough not to try and load
the entire huge seamless table into memory).

Hmmm. I must be md!

Cheers

Tim

Ps. I can't combine the tiles into larger ones to reduce the amount; a
concurrent system uses the same raster data and requires them to be
split into these 1 million tiles.

Does anyone know where I can find a side-by-side feature comparison
chart of the various GIS SDKs?

By SDKs I mean MapX, MapXtreme, MapObjects, TatukGIS, EasyMap, WinGIS.

The sort of features I mean are map format support, map manipulation
functions, programming languages supported, best-suited application
domain etc.

Thanks and kind regards

RE: MI-L Programming language for GIS

[Tim Smith]

Hi,

You can use the native MapBasic for MapInfo. Or you could go down the
MapXtreme/MapX route which allows you to create stand-alone GIS
applications using C++, Microsoft .NET (C++ and Visual Basic) or Java
for web-client/server type applications.
If you need to distribute your application to people who don't have
MapInfo licenses then you'll prolly need to use MapXtreme or MapX as the
run-time license is a lot cheaper than MapInfo.

As far as other GIS software development kits go, I'm pretty much a
novice.

Hope his helps.

Tim

RE: MI-L Programming language for GIS

[Tim Smith]

Perhaps consideration of cost is imporant. Investing the time and
training in learning C#/C++, purchasing .NET software/development tools
and then paying for run-time MapXtreme licenses may rule it out. It is
certainly a very big decision, and one we are still making - we're even
evaluating non-MapInfo SDKs which have royalty-free development
licenses.

for C#. They produce a lot of code samples, articles etc. that are very

MI-L Street directions

[Tim Smith]

Hi List,

I am using Navteq streets and want to show the direction of roads that
are one-way. At present, if I select the 'show line direction' *all*
roads have a blue direction arrow, so I have had to chop my roads layer
into two layers; one with one-way roads and one with normal roads, and
only set the line direction option on the one-way layer. Is there any
way I could create a new layer that contains only one-way symbols? The
layers have to be loaded into a MapX geoset, but I don't think that
would change matters.

A quickie... is there any way I can have a line style that allows me to
specify both the colour of the line, and the colour of the line 'edges'?

I apologise if the answer is obvious, but I'm a beginner at manipulating
maps in mapinfo.

Kind regards

Tim

Thanks for your reply Carolyn,

I've managed to split the roads into two layers, but what I'm ideally
trying to do is create a layer of one-way symbols/features rather than
split the road layer into two. In this way I was hoping to be able to
create my own one-way indicator appearance. The default 'line direction'
arrow is blue and too big, I want to display one-way roads with a red
arrow that's smaller. This is probably tricky to do.

I've got the line editor tool, but I can't seem to get it to create the
line I'd like. I want a yellow line that's four pixels wide with
one-pixel wide grey sides.

Kind regards

Tim

Hi Tim,

Ive never used Navteq so im not sure of the dataset and what it
contains, but is there some kind of attribute that separates one way
roads to normal roads.  This will allow you to select all your one way
roads using Query --> SQL Select, where column X = "one way attribute"
and save a copy of your selection into a new layer.  

With regards to the line style, there is a tool called Line Syle Editor
that allows you to create your own line styles, ive never used it to
create complex line styles but it could do what you want.  Ive searched
the web site for a copy but cant find one.

I hope ive understood you and this helps

Carolyn

RE: MI-L Street directions

[Tim Smith]

Thanks Mark,

Is there a way to create a one-way direction indicator from this 'To'
and 'From' info in MapInfo? I extracted these records using a query and
set the 'Show line direction' option, but the arrows go in the wrong
direction - I guess it doesn't get the line direction from the
'Direction_of_Travel' field.

Is there a tool that creates a layer of one-way indicators from a
Navstreets data? I don't have mapbasic, so can't write a tool to do it.

I've also been trying to find the Navteq table specification on the web
with no joy.

Cheers

Tim

Hi Tim,

In the NavTeq street data you will find an attribute called either
DIR_TRAVEL or DIR OF TRAVEL depending on the data you are using. 

The attribute will have any of the following three entries:

B = Both
T = To
F = From

The T and the F values indicate one way links. You should be able to use
this to display the T and F links differently to the B direction links
either on the same layer or in a query to separate them out.

Hope this helps.

Mark Prestwood.

RE: MI-L Street directions

[Tim Smith]

Thanks Dave,

I have everything working more-or-less.
The Direction_of_Travel field has three possible values; 'B'oth
directions, 'T'o and 'F'rom.
I have three tables for roads now; one with all roads, one with just the
'To' roads and one with just the 'From' roads.
I have set the line style of the 'To' and 'From' layers as left and
right chevrons respectively, and they overlay the full road layer. In
this way I can specify the colour of the one-way chevrons without
affecting the colour of the underlying road.

Funnily enough, I just managed to get the road colour effect I desired,
and it's the same method as you have suggested!
I have a solid grey road that is 6-pixels wide with a 4-pixel wide copy
on top which is coloured yellow. This gives the 1-pixel wide edge I
wanted.

Next problem: how to show bridges?! I'll have to interrogate the roads
table

Thanks for your help.

Cheers

Tim

Right, MIPro won't know what that column means -- it
just shows you the order of the lines' nodes as
they're stored internally in the .MAP file.  But I
would think _one_ of the two query tables ('To' or
'From') would have the arrows in the right
direction... (?)

You should be able to set up the line style you want
by adding each query table separately to your map, and
applying a Style Override to it ('Display' button in
Layer Control).  If the arrow-to-the-right line style
gives you the wrong direction, apply the
arrow-to-the-left style instead.  (And there's a
double-ended arrow style you can use for 'Both'.)

If you want to avoid all the querying, you might try
setting up an individual-value line-style thematic on
the Direction_of_Travel column, and altering the
individual styles as described above.

Unless I'm forgetting something, line styles only ever
have one color attribute that you can change in MIPro
-- so you can have any second color you want as long
as it's grey...  Except you might be able to pull some
clever tricks with the Line Style Editor; I forget
what the limitations are exactly.

It sounds as if your best bet might be to add each
query table to the map _twice_, and apply a wider line
style (with your 'edge' color) to the lower layer in
each pair.  With the right combination of widths I
think you can get the two-color effect you're
describing.

MI-L Default .tab color

[Tim Smith]

Hi!

Where is the default color of a tab stored?
e.g. when I load the ocean.tab (supplied on the MapX 5.0 install CD)
file into MapInfo, it is blue.
I've looked at the .tab file in a text editor and can't see any color
setting?

So is it stored in the .map .dat .id ?

Cheers for any help

MapInfo doesn't support 16-colour RLE (run-length encoded) bitmaps (BMP). 
256-colour RLE bitmaps work fine.
I've got approx. 1-million map tiles that are in this format - that's gonna

Thanks for putting things more clearly than I did.. BTW, GIF isn't always 
lossless. It can do nasty things to your colors if you chose a low number of 
colors (less than there are in your maps).  But  it compress very well
if you have few colors.   Sometimes I export large Tiffs and convert them
to GIF in Photoshop. Anyway, you can't export directly from MIP, as was 
requested by the person who asked the question.

Also to be more precise :  png or tif is the way to go if you have to stay in 
raster mode. But if you have much details and fine lines in your maps, the 
vector format is always much better. It's really a pitty that MapInfo doesn't 
allow exportation in eps mode.. I wonder why it is so ?  because MIP don't want 
to be a fee to Adobe, or whoever invented that postscript
format ?   or may be it is because that would imply the translation from
rgb values in cmyk values and the implementation of a lot of new code ? who 
knows..  any way, it's a pain to be left with only the wmf format, because in 
the press world they don't like window things.. MIP should also implement CMYK 
palettes. With RGB printing to real world press print is a nightmare.

Hi Christiane,

Please let me add a few comments on your raster formats. There are 3 kinds

of bitmap formats:

Uncompressed: TIF, BMP, PSD
Compressed, loss-less: PNG, TIF, GIF
Compressed, with loss: JPG

Main comment is PNG is not a compromise between size and quality, since quality 
is as good as in the uncompressed formats. Secondly: TIF exists both in 
compressed and uncompressed versions (both loss-less). That is called "TIFF 
LZW" in MapInfo.

But I agree, when you say PNG is the way to go :-)

Hi,

I encountered the same kind of problems one year ago while we prepared our 
atlas for print. When you chose to export your windows, there are several types 
of format which you can chose.

a) Raster format export your maps as if they were photographs. That could 
create huge files depending on your resolution and map dimension. Nowaday 
printers takes up to 1200dpi if they are good printers. But 600 dpi shold be 
good enough.. With raster format, things could go wrong in different ways; one 
important thing lies with PageMaker too : are you sure that you have chosen the 
right options in dealing with the picture ?  Sometimes it can compress pictures 
which isn't a good idea. There are two kinds of raster formats : the 
uncompressed ones : *.tif, *.bmp, *.psd;  the first is the most frequently 
used; the second is a Microsoft format and the last is a Photoshop format. Of 
the three, the tif format is probably the most frequently used. Among the 
compressed files format, you have the *.jpg and the *.png.  The frequently 
encountered jpg format, is a compressed format which creates bad artifacts with 
limits and could blurr your maps; it's made for photographic images, not for 
charts or maps which should keep clean borders. The *png format is also 
compressed but of better quality. It's the way to go if you want a good 
compromise between size and quality. If space isn't a criteria, then the Tif 
format is better. As far as compressed format goes, it would be better to have 
*.Gif format rather than *.jpg. The former is able to keep clean borders, while 
the other isn't.

Mr. VanDruten,

I have waited to comment on your note, below, until I
could comment in civil terms and make any points in a
civil and ordered manner.

Two individuals have asked what they could do to
assist in a continuing natural disaster, in effect you
told them not to bother, that the federal government
would handle it and that their platform of choice was
not of any use anyway.   Perhaps you missed the
lessons in grade school, for want of a horseshoe the
kingdom was lost .I say to anyone who wants to
see if they can help, you GO!   Do your best and see
how you can help.   I would like to assist if there is
any way to do so also.

Mr VanDruten, you do not know how they can assist, of
if whatever job they do will come up with a way to
save several or hundreds of lives, nesessity is the
mother of invention.   I congratulate you on being a
certified as a Federal GIST within ROSS, it is
certainly an accomplishment.   When it comes to being
in the right place at the right time and being able to
assist someone in need, it doesn't mean squat.

These two gentelmen can do whatever analysis they come
up with and can hand over their work to FEMA or
whoever else takes over so there will be something to
start with.   I know there are protocols and standards
to observe, but helping out in an emergency means you
do what you can with what you have where you are at.

Perhaps we might look at this differently, how can we
as a MapInfo community support the recovery effort.  
Can we work as a group on projects where there is no
coverage, but a need?   Is there something we can lend
our talents to that might make a difference to the
folks who have been so hard hit?   We are a community
who have professional talents that we can employ to
help those who have lost most, if not all, of what
they have.

Let us not let wet blankets like Mr. VanDruten dampen
our instincts to assist where we can to help others.  
Let's see what we can do.   I'm contacting MSNBC to
see what small town there are that need help and don't
have any resources.   It's a long shot, but it's
something.

MI-L Exporting a bitmap for processing

[Tim Smith]

Hi List,

An interesting one...

I want to use some mapinfo maps in our mapping display engine. Our
engine only supports raster maps, so I thought I'd export my mapinfo
vector map as a bitmap. Just a couple of problems with this:
Our engine needs the map to be projected as WGS84 UTM and the bitmap
must be the same meters-per-pixel vertically & horizontally.
I have changed the projection ok, but now I need to be able to export
the map at a given meters-per-pixel and also know the exact easting and
northing of the bottom left pixel. The exported image will be huge - at
a far greater resolution to the screen, so the meters-per-pixel
resolution will be different.

I'm sure this is possible - perhaps there's a tool to do this better
than Mapinfo's built-in exporter.

Cheers for any help with this!

RE: MI-L OFF TOPIC: What's the best GIS

[Tim Smith]

Bob Ross rules!

I *have* to use MapInfo because it has MapX - which I use to draw many
real-time features that update many times a second.
Arc gis's objects just couldn't compete performance wise - in fact the
rendering engine I use with MapX is rougly 1000x faster than the method
I can use that would integrate it with ArcGIS's developer objects.
That's the reason I use MapInfo.

ArcInfo
* Rubbish

MapInfo

[Mapinfo-l] Map rendering engines

[Tim Smith]

Hello list!

I was wondering if anyone knows of any good map rendering engines (like
MapX) that can display MapInfo maps?
I want to be able to embed the renderer in my Windows application, and
ideally it should have a C/C++ api and allow features to be drawn on the
map.

Any ideas?

Cheers

RE: [MI-L] Transparency

[Tim Smith]

Jerry,

Thanks for your reply.

I was thinking of raster formats which have an 'alpha' channel. This can
be used to allow a certain amount of the underlying layer show through
(like in Photoshop).

I tried the using the layer-control, but the 'Style Override' box is
disabled - I guess this is because I have a seamless raster layer?

Tim,

What do mean by semi-transparent? Can you achieve the functionality with
translucency?

You can make a raster layer transparent in MapInfo
1.  Choose Map > Layer Control. The Layer Control dialog box
displays.
2.  Press the Display button. The Display Options dialog box
displays.
3.  Check the Style Override box
4.  Click the transparent checkbox and choose your colour
5.  Click OK.

To specify a transparent fill pattern for vector:
1.  Make the layer where the objects reside editable (Map > Layer
Control).
2.  Choose Options > Region Style. The Region Style dialog box
displays.
3.  Check the Background box to provide a background colour for a
fill pattern. Clear the box when you only want to see the pattern.


As for MapX, it should transfer over fine. Check out this link if you
are having problems

RE: MI-L Distance & Bearing Calculation

[Tim Smith]

Thanks Stefan,

What I need is a certified piece of software that can calculate the distance and 
bearing. It doesn't necessarily need to be MapInfo (or implemented in). I have found 
various on-line converters but I'm not sure which ones are reliable.

I am surprised MapInfo does not include GIS calculation tools for bearing and distance 
calculations - or have I just missed something?

I downloaded Sean Reese's application, but I need to be able to manually enter the 
lon/lat for each point.

Do you think this calculator would be a good choice?

Dear Tim,

You can try this:

section write bearing. Sean Reese wrote application which you need. 2. or if you need 
ONLY distance, you can find SQL statement for it in 
older mails on this list.
3. or if you have a huge number of the points, you can download CalcDist 
PRO (from http://www.terris.sk) which will do the job instead you.

Hope this help you.

MI-L Multimap URL construction

[Tim Smith]

Hi,

I bit of a strange one.

Does anyone know how to format the Multimap (www.multimap.com) URL to
give directions between two lat/lon points via a series of other lat/lon
points?

Here's Multimap's page for entering a directions-finding request:

http://www.multimap.com/map/routein.cgi?POINT1.PASSTHRU-SPECIFIED=1&POIN
T2.ISWAYPOINT=1&POINT3.PASSTHRU-SPECIFIED=1&CLIENT=public&ROUTEPOINTSCOU
NT=3


I'm writing a web application that ends up with a list of lat/lon
positions and I need to display the route between them. I know multimap
has the facility to do this as I've seen other applications in the past
that do it. I'm just not sure what format of the URL should be.

Thanks for any help!

We use maps at the moment that are raster renderings of vector maps.
They come from TensingSKS and they have their own mapping software that

I'm surprised that a market leading product such as mapinfo doesn't have

You can't do that with MapInfo. This surprises me too. You'd think that 
after so many years MapInfo would have added a feature such as this that

so dramatically improves the appearances of a map. 

I wrote a simple MapInfo to SVG translator that shows that when you
display a map via SVG, the anti-aliasing really improves a map's graphic
quality. If you want to try SVG, you can download the translator from
http://www.gisnet.com/notebook/SVG_mapping.htm.

MI-L Setting the Datum

[Tim Smith]

Hello!
 
Does anyone know what the datum value is for WGS84 when setting the
datum in MapX with the CoordSys.Set method?
 
The projection type is the first parameter and is defined in the mapx.h
file as miLongLat. The problem is that the
datums are not defined, you just pass a 'short' integer.
 
The mapx help only goes as far as to say...
"A Datum object or a supported datum number (such as 62 for the "NAD 27"
datum for the Continental US)."
 
Thanks for any help

RE: MI-L Setting the Datum

[Tim Smith]

I'm also having problems using CoordSys.Set and omitting parameters.

In VB you can just set the projection i.e.
objCoordSys.Set 12

But in C++ MapX requires ALL of the parameters to be filled. So I have
to know all
Of the following parameters for WGS84 ...

OBJECT.Set (Type, [Datum], [Units], [OriginLongitude], [OriginLatitude],

 [StandardParallelOne], [StandardParallelTwo], [Azimuth], [ScaleFactor],

 [FalseEasting], [FalseNorthing], [Range], [Bounds], [AffineTransform] )


Has anyone used this function in MapX and C++?

Kind regards

MI-L Static feature size

[Tim Smith]

Hi,

I'm trying to add a circle feature to a layer using MapInfo's MapX.
I want the circle's radius to be relative to the screen, i.e. it doesn't
resize when zooming in or out. I want it's position to be relative to
the map (WGS-84).

Does anyone know what styles to apply when creating such a feature?

This is the code that I have at present...


CMapXFeatureFactory featureFactory = GetFeatureFactory();
circle = featureFactory.CreateCircularRegion(miCircleTypeScreen,
 point,
 0.1, //100m
 miUnitKilometer,
 16); //16 segments to
circle
circle.SetType(miFeatureTypeLine);

CMapXStyle style;
style = circle.GetStyle();
style.SetLineColor(RGB(255,0,0));
style.SetLineWidth(3);
style.SetLineStyle(1);
circle.SetStyle(style);

// Add circle feature to the layer.
GetLayers().Item("circles").AddFeature(circle);

MI-L Dynamically updating map features

[Tim Smith]

Hi,

Is it possible to update a MapX 'UserDrawLayer' without updating the
underlying map?

I rapidly change what is drawn to the user-draw layer. This means that
the entire map is redrawn even if I am only changing a small amount of
the user-draw layer.

Possibly the problem is that I don't know how to get the 
'MAPX_DISPID_DRAWUSERLAYER' message to be invoked without calling
'Refresh()' on the entire map.

This is a tricky one!

Kind regards

Tim

RE: MI-L MapX features

[Tim Smith]

Thanks for your reply Katrin,

If I set my feature's key with feature.SetKeyValue(), I don't get the
same key if I do feature.GetFeatureKey().
Perhaps I have not setup my layer properly. Do you have to create your
layer in a special way to allow you to change the feature key?

Can you set your feature to have any key string? I guess you have to be
careful not to set the key the same as an existing feature.

Thanks for any help.

questions - it's better to come here. There are some people, that helped
me with MapX greatly. MapX forum in mapinfo.com  - it's rather way of
discussing problems with MapInfo techsupport

 

 

Hello MI-L gurus!

Has anyone used the 'CMapXFeature::SetKeyValue()' method in MapX?

Does anyone know if it works?

I'm interested to know if anyone on MI-L uses MapX. Is there a
forum/mailing-list just for MapX?


Kind regards

Tim

MI-L New lat/long from distance/bearing

[Tim Smith]

Hi List,

I have a latitude and longitude in WGS-84.
I want to calculate a new point based on a bearing and distance from
this position.

Difficult bit -
I want to calculate this using MapX, or alternatively I could use some
C/C++ code.

Thanks for any help with this

Kind regards

RE: MI-L New lat/long from distance/bearing

[Tim Smith]

Hi,
Thanks for people who have helped so far with this,

I want to draw a line in MapX between two points. The function in MapX
to do this takes two WGS-84 lat/long points.
I don't have two lat/long points. I have one lat/long, an angle in
degrees and a length in meters.
I need to calculate the second lat/long (unless there is a MapX function
that can draw a line - given a position, angle and distance).

A C++ algorithm to do it would be fine. I can't believe MapX doesn't
support such a calculation.

Tim

RE: MI-L New lat/long from distance/bearing

[Tim Smith]

Thanks Terry.

I'm not 100% sure, but with this approach I'd need my easting/northing
to be in the same units as the distance.
Is this correct?

My lat/long is WGS84 and my distance is in meters.

Kind regards

Tim Smith

Tim,

I don't know MapX and would need repriming on C, and I'm not sure if
there is a ready-made function to do this, but I would use trig to do
this

 N
 !
 !  w   target
-!-o
 !/
n!   /
 !b / L
 ! /
 !/ 90-b
-o-! W
w
 Start point

You have bearing, angle b, and distance, length L
Sin( b) = Opp/Hyp

So Sin( b) = w / L
So w = Sin( b) * L, giving you your distance West

Tan( b) = Opp/Adj

So Tan( b) = w / n
So n = Tan( b) * w, giving you your distance North

This works for bearings of < 90 deg so will need to be rethought for >
180, > 270 etc. but I'm sure you get the drift.  As to whether MapX has
functions to get the lat/long, given the distances N and W, I don't
know, but I hope this helps

Terry

RE: MI-L New lat/long from distance/bearing

[Tim Smith]

Hi Lars,

Thanks for your reply.

I may use some of your ideas to help me solve this.
My application is in C++ using MapX, so I have to use the functions
available in MapX. The calculation has to be done in code and quickly.

I was thinking I could use your idea of converting the point to a meter
grid point and then applying trig to get the second point and then
converting the new point back to WGS84.

The trig part is ok.

I now need to know how to convert between WGS84 lat/long and a meter
system - probably UTM.

Does anyone know how this is done?

Cheers

Tim

Hi Tim,

If you don't want to go all out on formula gymnatics, I may have an idea
for you.

By using the coordinate support in MapInfo to my advantage, I've
implemented adding meter offsets to GPS positions this way :

1. Set the coordsys to LatLong/WGS84, and obtain the coordinates of the
point (user click in my case) 2. Switch the coordsys to a meters based
stereographic projection with the lat/long point as center, i.e. as
(0,0) 3. Create a new point feature using simple 2D geometry, e.g. 300
meters east, 200 meters south, i.e. in stereographic position
(300,-200)
4. Switch back to LatLong/WGS84, and retrieve the coordinate of the
created point feature 5. Voila, you've had MapInfo calculate a flat
offset to a geographic position.

It was implemented in Pro/MapBasic, which is far better at this this
MapX. But even in MapX you can manipulate the coordinate system setting
to your advantage, and you can create point features on the fly, so it
ought to be possible even in MapX to use the above method.

And yes, it's an approximate method that deteriorates with distance, but
for smaller offsets it should be perfectly ok to use.

Good luck.

RE: MI-L New lat/long from distance/bearing

[Tim Smith]

Erik,

Thanks for your reply.

I am also working over small spaces (< 100km area), so I could use
normal trig as you mention. But I must first convert the lat/long to a
meter grid because my distance is in meters. This is because X2= x1 + L
* sin(ang) will mean nothing if x1 is in decimal degrees and L is in
meters.

Kind regards

Tim

The further the distance, the less accurate it needs to be.
So +/- 1 degree is probably the best way to represent the accuracy I
need.
e.g. roughly +/- 1.7km @ 100km and 1.7m @ 100m etc.

RE: MI-L New lat/long from distance/bearing

[Tim Smith]

Hi Erik,

I understand what you're saying. I still need to be able to convert from
my lat/long to meters before I can use the trig.

E.g.
My latitude is 50.9051 degrees and longitude is -1.0649 degrees. My
angle is 45 degrees and my distance is 500m.

If I use the trig as it stands I would get a target of.
Latitude X2 = 50.9051 + 500 * sin(45) = 404.46

This is incorrect.

What I need to do is convert my lat/long into a meter grid - lets say
UTM.
I now have 636056 easting and 5641055 northing

Now the trig works

X2 = 5641055 + 500 * sin(45) = 5641409

Now convert back to degrees.

50.9083

What I need to be able to do is convert from my position in degrees to a
meter system.


Cheers

Tim

Tim,
Here's an idea.
Can you just create a line of any odd length but pointing in the right
direction 
( that's my X2= x1 + L * sin(ang) which as you point out isn't making a
lot of sense (but use Deg_2_RAD conversion and it will)) Now get the
length MeterL of this object in meters (that should be possible even
with MapX) Now you wil have a L to meter conversion in the part of the
globe where you are (L/MeterL) You can now create a new line with the
right L and the right Direction.)

Is this an idea you can use?
Best regards
Erik

RE: MI-L New lat/long from distance/bearing

[Tim Smith]

Thanks Uffe,

The example was a great help.
I will probably use the way you mention, although I did find another way
to do it, but which only works over small areas.

lat = latitude of first point
long = longitude of firat point
angle = angle in degrees or radians
dist = distance to go from lat/long in meters

lat1 = lat + (dist * sin(angle) / 94.6123
long1 = long + (length * cos(angle)) / (94.6123 * cos((lat + lat1) /
2))

It seems to work

Either way looks good.

Cheers

Tim

What I need to be able to do is convert from my position in degrees to a
meter system. 

If you want to do that, you will find the formulas here
(http://www.gpsy.com/gpsinfo/geotoutm/), but it is much more complicated
than doing the calculations, I suggested:

lat1 = 50.9051 degrees = 50.9051 / 180 * pi radians = 0.88846 radians
lon1 = -1.0649 degrees = -0.018586 radians tc = 45 degrees = 0.785398
radians d = 500m = 500 m / 6378130 m = 0.78392 radians

lat=asin(sin(lat1)*cos(d)+cos(lat1)*sin(d)*cos(tc))
IF (cos(lat)=0)
  lon=lon1  // endpoint a pole
ELSE
  lon=mod(lon1-asin(sin(tc)*sin(d)/cos(lat))+pi,2*pi)-pi
ENDIF

I get these values as result:
lat = 50.908275919285
lon = -1.06993680690127

Now I entered these 2 points into a TAB file and measured the distance
and get 500 meter as expected.

Kind regards

Hi Nola,

Just a hack, but...
You could press the 'Print Screen' key on your keyboard, paste the image
into Photoshop(etc.), crop and print.

I'm using MI v7.5
Have created a beautiful 3DMap with my raster layer (Satellite image)
draper over the DEM. Unfortunately what I can see on my screen won't
convert to either a layout window or PDF.  I have tried Save Window As-
jpg, tiff & bmp still no success. No matter what I try I cannot get the
raster layer to print with the 3D map all I get is the DEM. 
The Raster layer seems to be invisible to the Layout window also. The
PDF ignores it as well. Please help with any suggestions if you have had
success creating a PDF or a print from a 3Dmap window which has a Raster
image draped over the DEM. Cheers, Nola

Hi List,
 
How can I save my map which uses British National Grid projection to use
WGS84 lat/long?
I have some third-party software which doesn't like OSGB mapinfo maps.
 
Cheers for help

Doh, worked it out - was a case of RTFM.
 
Sorry to bother everyone.
 
(Save-As & then choose projection)

[MI-L] MapXtreme 2004 and ActiveX

[Tim Smith]

Hi List,

Is anyone using MapXtreme 2004 in an unmanaged-code environment?
Does anyone know if this is possible?

I have an old MapX application and I'm trying to replace it with
MapXtreme2004 without having to re-write the application in .NET

I know it is possible to 'wrap' most .NET controls as an ActiveX
control, but for some reason the MapXtreme 2004 MapControl does not like
being treated like this (it won't initialise).

Any ideas?

Cheers!

Tim

[MI-L] MapXtreme2004 methods

[Tim Smith]

Hi,

Does anyone know the MapXtreme equivalent of these two MapX methods.

This method sets the distance units used - like Nautical-Mile/Kilometers
etc.
I have found the enum MapInfo.Geometry.DistanceUnit, but don't know how
to set the units 
SetMapUnit(...)

This returns the width of the map window in units specified by the
SetMapUnit() method
GetMapScreenWidth();


Cheers

Tim
