Re: MI multiple raster image registration

2000-09-13 Thread brendan . a . henry



Grantley,
The "quick & dirty" way of getting two photos registered is simply to register
each individually.
You can then combine them in the map window.
You have to be careful that where the maps "overlap" must be about the same
distance from the centre of each photo, due to scale differences towards the
outside of the photo & radial displacement of trees, etc.  If necessary crop the
raster files before trying to register them.
If the photos don't align very well, you can always have two map windows (a
photo in each) and align them in the layout window.

If you are planning to use photos regularly, and save registered photos as a
single raster image, you may want to invest in ER Mapper (or similar)

Subject:  MI multiple raster image registration



List,

I am writing to ask what may be a very simple question which has me stuck
being a relatively novice user of MapInfo.  I am using MI 6 Pro, and I have
scanned two 1:100 000 maps which are both in the same projection and have
the same datum information.

I have no problems registering one of these raster images to create the
required *.TAB file to use in MapInfo, however I need to register the two
images and join the two together to select a piece of the newly created
image to use as my base map.

If anyone could tell me in a relatively simple way how to join the two
together or know of a better way to go about the whole process then I am
most interested to learn.

This is quite frustrating as I feel as though it is a relatively simple
problem which is turning into a real mountain at the moment.

Any help would be greatly appreciated.

Grantley

Re: MIF file format

2000-08-30 Thread brendan . a . henry



Preetha,
MapInfo can read directly from MIF files.  I'm just guessing that your purpose
might be to export MIF/MapInfo files to another format.  You may want to
elaborate.
In any case the mif file will have a similar header (if not exactly the same) -
certainly the same order.
However, in some cases there will be extra lines (e.g. Unique ), and the
Coordsys line may be different depending on the projection of the map.

Hope this helps!

Subject:  MIF file format



Hello,

I am trying to write a program that can read MIF files.  I have downloaded
MIF file format technical description from
http://www.mapinfo.com/community/library/interchange_file.pdf.

The MIF file header contains several clauses. Is it necessary that these
clauses should occur in the order which they have been mentioned in the
document or can there exist MIF files where the order of information in the
header is different from the one mentioned in the document.

I would appreciate any help in this regard.  Thank You in advance.

Regards
Preetha.

MI Choosing/Using alternative pen files

2000-08-30 Thread brendan . a . henry



Hello listers,
I would like to be able to choose a different .pen file from within MapInfo or
possibly in a MapBasic script.
The standard is mapinfow.pen which I can certainly change, but I would like to
have the option of doing this after having opened MapInfo.
Can this be done?
TIA,
Brendan Henry

MI Customizing linestyles

2000-07-23 Thread brendan . a . henry



I have a query regarding the creation of new linestyle patterns.  I would like
to be able to create new pattern styles.  In Appendix J of the MapInfo
Professional Users Guide, it mentions that the pen file can be modified using a
pen editor.  Has someone done this & if so can you provide further details.
