[Qgis-user] How often is rebuilt qgis-dev in OSGeo4W?

[Junior Delaz]

Hi all,

I always thought that nightly builds in OSGeo4W were built every night.
Since the feature freeze begins, I try every day to download a new version
of qgis-dev but it's not always available. I both work with 32 and 64 bits.
"32 bits" pre-release is the same since many days (may be the beginning of
the week, if i'm not wrong), has several days of delay on "64 bits" and is
not thus really relevant to test new fixes. Last week, it was "64 bits"
that hasn't been changed for 2 or 3 days.

Can someone explain me how that works, please?
Thanks.

Re: [Qgis-user] TAB file export - Solved

[Brett Adams]

Thanks Ramon.

Removed the spaces from the field names and the export worked perfectly.
The projection shifts from EPSG:28351 to EPSG:32751

Re: The projection change EPSG:28351 (GDA94/MGA-zone51) to EPSG:32751(WGS84
UTM zone 51S). These are essentially identical projections, possibly cross
referenced in projection definitions or just copied. 

Exporting MID/MIF files or upgrading to 2.3 allows the spaces in the field
names.

Thanks everyone.

Hi Brett,

I suspect it's the spaces in the field names...

I've installed QGIS 2.2 on Win as well, there the projection is available,
but it looks some how strange, there must be any difference between both,
this has to be the DATUM
POSGAR 2007 is WGS84 EPSG 1062
POSGAR 98 is WGS84 EPSG 6190
does some one knows what's the difference on this?

The projection is available in QGIS 2.2 on Windows. Parameters are:

+proj=tmerc +lat_0=-90 +lon_0=-72 +k=1 +x_0=150 +y_0=0 +ellps=GRS80 
+towgs84=0,0,0,0,0,0,0 +units=m +no_defs


for Argentina 1. The others just have a different lon_0 and x_0.

So no problem with datums. +towgs84 is all zero, even for Posgar94 and 
Posgar 98. Posgar 98 and 2007 have identical paramaters, Posgar94 has 
WGS84 ellipsoid.

Ubuntugis currently has limited support for Ubuntu 14.04 trusty.

You need the gdal package, and that has just been added today (4 hours

Re: [Qgis-user] QGIS: Reduction of resolution via pyramids

[Rahkonen Jukka (Tike)]

Hi,

See the comments on http://hub.qgis.org/issues/10563

I recommend you to estimate how the scale 1:25000 turns into pixel size.

I was remembering that screen resolution is about 91 pixels per inch but let's 
check it.
Screen dot size=0.28 mm
One inch is 25.4 mm = 2.54 cm = 0.0254 m
25.4/0.28 = 90.71

Let's assume that the native resolution of your images is 1 m. One inch on 
screen takes 90.71 meters of your data so the scale is
90.71/0.0254 = 3582.7

Overview level 2 (2 m pixel size) would correspond to  screen scale 1:7165
level 4 (4 m) to scale 1:14330
level 8 (8 m) to scale 1:28661.

Internal overviews can be used with tiff format.  Overviews will be stored 
inside the master tiff file which is handy because the one single file contains 
all, both the native data and all the overviews. It is also using  a bit less 
disk space than if overviews are written into external file. External overviews 
in .ovr format are tiff files with the same base name than the source layer and 
with extension .ovr. External overviews in Erdas format are fundamentally same 
but stored in Erdas Imagine format, not tiff. As far as I know the speed with 
GDAL programs is the same but I can Imagine that Erdas Imagine would like its 
own format better. Because you have a virtual raster as master layer you can't 
use internal overviews.

I would say that you can feed the numbers into a spreadsheet if you want to 
play and understand how it goes, but it is not at all necessary. If you think 
that using 25% extra disk space for level 2 overview is too much, start from 
level 4, it is certainly worth the 6.25% that it costs.

If you are happy with your virtual raster collecting 875 jpegs then good. 
However, jpegs and pngs are the worst alternatives of all for this kind of 
usage because the whole file must be decompressed even if only a small part of 
it will be needed. Convert them into tiled geotiffs which are internally 
compressed with jpeg compression and you will be much more happy. Of course if 
you enjoy speed, which I do not know.

GDAL takes automatically the resolution that is closest best to the asked 
output resolution. If you ask 10 m pixel size for the output, it does not start 
from 1, 2, nor 4 meter resolution which would be waste of resources. Instead it 
takes the 8 m version and resamples it into 10 m pixel size. GDAL does not take 
16 m version because by doing that the quality would be unnecessary bad. Makes 
sense, doesn't?  How to control, I don't know. Probably in the code but of 
course by deleting the overviews you can force GDAL to start from the native 
resolution.

Here are the basic commands to use if you have 3-band aerial images. For raster 
maps LZW of DEFLATE compression may suit better.

gdal_translate -of gtiff -co tiled=yes -co compress=jpeg -co photometric=ycbcr 
input.tif output.tif
gdaladdo -ro --config COMPRESS_OVERVIEW JPEG --config PHOTOMETRIC_OVERVIEW 
output.tif 2 4 8 16 32 64

Dear Jukka,



thank you for your answer.

I still don't know how to build pyramids just for defined scale ranges (in my 
case: smaller then 1:25.000).

I've forgotten to tell you an -maybe important- detail: I'm working with a 
virtual raster catalogue which i built out of 875 .jpgs (4000x4000).

When building pyramids, i've always used the option "external (Erdas 
Image.aux)".

Can you shortly explain the difference between the 3 options (external .ovr, 
internal, external .aux)?

I couldn't find an advice in the handbook or via google.

The QGIS instructions say that after building pyramids QGIS automaticly takes 
the best resolution when loading raster layers. So how can I influence what 
resolution QGIS chooses?

Thanks again for further help!

Dear Jonathan,

 

thank’s for answering.

I’ve forgotten to tell you an –maybe important- detail: I’m working with a
virtual raster catalogue which i built out of 875 .jpgs (4000x4000).

 

Zoom to best scale (100%) ends in scale 1:668 (for one of the 875 tiles as
well as for the virtual raster catalogue of the 875 tiles).

So if I understand you right I have to calculate the 106x106 pyramide and
smaller ones respectively level 37,5 and higher ones, right?


Kind regards,

Hi Julian,

  You can specify at what levels pyramids are created. That's what the
"resolutions" box on the right does. The problem is, knowing which levels
you want.

 

So if your data is a 4000x4000 tiff then it'll offer to create pyramids at:

2000*2000
1000*1000
500*500
250*250
125*125
63*63

 

I'm going to guess at the answer to your question - I believe what you need
to do is the following:

 

- Find out what the scale is for "Zoom to best scale (100%)" for the raster.
For my raster it's 1:9,449 (yours will be obviously be different).

- So the 2000x2000 pyramid will have a scale of 1:18898 (i.e. double 9449).
So you wouldn't want that level. In this scenario you may want 1000*1000 -
which would be for a scale of 1: 37796 (double 1:18898).

 

So with some simple maths you can figure out which pyramid levels you want.
I suppose it would be a good feature for QGIS to show scales rather than
tile sizes in the "resolutions" box. I'll go open a feature suggestion for
that one.

 

Cheers,

Jonathan

 2. Give it a name
 3. I done a search online for POSGAR2007 and came across this page
http://spatialreference.org/ref/sr-org/posgar-2007-argentina-2/
 4. If you select PROJ4 copy the text and paste it into the Parameters

 5. You can do a test then at the bottom, inputting the WGS84

[Qgis-user] Please Help: Attribute Table crashing constantly

[someone1]

Hello,

For reference: qgis 2.2, OS X 10.9.3, 4 GB of RAM

I am editing a project that involves me populating literally thousands of
segments, but yesterday qgis started crashing after I tried to save my last
round of edits. After that initial crash, every time I tried to open the
attribute table of the shapefile I was working on, qgis would continue to
crash. Even today, after letting my computer sleep, I tried reopening the
attribute table and again -- crash.

Tried selecting by expression the fields I was working on for the past few
days -- Crash.
Tried looking at the attribute table of the original shapefile I pulled
information from (same attributes) -- Crash. 
Tried looking at the .dbf file in excel to check on my edits -- Gone.

I have no idea what's happening and I need to work on this shapefile because
it's apart of a major project for one of my professors. Has anyone here been
able to overcome this issue without having to give up on losing two days
worth of work? 

Thanks.

Re: [Qgis-user] QGIS: Reduction of resolution via pyramids

[Julian Schall]

Dear Jukka,

 

thank you for your answer.

I still don't know how to build pyramids just for defined scale ranges (in
my case: smaller then 1:25.000).

I've forgotten to tell you an -maybe important- detail: I'm working with a
virtual raster catalogue which i built out of 875 .jpgs (4000x4000).

When building pyramids, i've always used the option "external (Erdas
Image.aux)".

Can you shortly explain the difference between the 3 options (external .ovr,
internal, external .aux)?

I couldn't find an advice in the handbook or via google.

The QGIS instructions say that after building pyramids QGIS automaticly
takes the best resolution when loading raster layers. So how can I influence
what resolution QGIS chooses?


Thanks again for further help!

Kind regards,


Julian Schall

There are check boxes for overview levels in the Build overviews panel.

Level 2 means double the original pizel size etc. Leave for example levels 2

and 4 unchecked. However, level 2 means 25% extra disk space but level 4

only 6.25%. Thus it may not make sense to skip other levels than 2. Remember

to compress also the overviews and test with external overviews which you

can easily delete and continue with new tests. Internal overviews can be

removed so that they are no more used but operation does not make image

files smaller.

Yes, it is Django app, which can be easily adapted to other backend. We
export required informations from QGIS project to some metadata file (by
GIS.lab Web plugin ) and send them together with QGIS project file to
GIS.lab Web. If one can produce the same metadata file, GIS.lab Web will
start app.

We use similar technologies as QWC, but it is other project.

Hi Andrea, as I have wrote in my previous response, GIS.lab is much more
than GIS.lab Web application - the goal is to build complete and integrated
infrastructure/ecosystem for systems deployment and management, GIS data
capturing, data processing, analysis or web publication. We have chosen one
tool for one task and we try to integrate them together as good as possible
(and improve chosen tools).

Re: [Qgis-user] GPS issue on android tablet

[Richard McDonnell]

In saying all that, I have just seen something which may be iv interest, 
besides the NRTK there is also Precise Point Positioning (PPP), which 
can be provided over a data connection (internet) which is called iPPP. 
This might be something worth checking out.

Re: [Qgis-user] GPS issue on android tablet

[Richard McDonnell]

Hi,
Most mobile devices now utilise this Assisted GPS or (A-GPS), its main 
use is to speed up initialisation times on mobile devices.
I am afraid though that in relation to accuracies, you are still looking 
at approximately 3-5m at best.
 As discussed previously, the only way to get sub meter accuracies (at 
present) is to utilise NRTK which is usually a subscription based 
service, requiring 3rd Party software.

Richard McDonnell

There are check boxes for overview levels in the Build overviews panel.
Level 2 means double the original pizel size etc. Leave for example levels 2
and 4 unchecked. However, level 2 means 25% extra disk space but level 4
only 6.25%. Thus it may not make sense to skip other levels than 2. Remember
to compress also the overviews and test with external overviews which you
can easily delete and continue with new tests. Internal overviews can be
removed so that they are no more used but operation does not make image
files smaller.

Re: [Qgis-user] QGIS: Reduction of resolution via pyramids only for defined scale range

[Jonathan Moules]

Hi Julian,
  You can specify at what levels pyramids are created. That's what the
"resolutions" box on the right does. The problem is, knowing which levels
you want.

So if your data is a 4000x4000 tiff then it'll offer to create pyramids at:

> 2000*2000
> 1000*1000
> 500*500
> 250*250
> 125*125
> 63*63


I'm going to guess at the answer to your question - I believe what you need
to do is the following:

- Find out what the scale is for "Zoom to best scale (100%)" for the
raster. For my raster it's 1:9,449 (yours will be obviously be different).
- So the 2000x2000 pyramid will have a scale of 1:18898 (i.e. double 9449).
So you wouldn't want that level. In this scenario you may want 1000*1000 -
which would be for a scale of 1: 37796 (double 1:18898).

So with some simple maths you can figure out which pyramid levels you want.
I suppose it would be a good feature for QGIS to show scales rather than
tile sizes in the "resolutions" box. I'll go open a feature suggestion for
that one.

Cheers,
Jonathan

[Qgis-user] QGIS: Reduction of resolution via pyramids only for defined scale range

[Julian Schall]

Hello members of the mailing list, 

 

I would appreciate help on the following problem: 

I would like to improve the performance of a raster layer. Of course I can
build pyramids for that purpose. But in the scale ranges from 1:1 to
1:25.000 I need maximum resolution and detail. In this scale range, the
performance is sufficient even without pyramids. 

Ideal would be that the pyramids respectively the reduction of the
resolution with improvement of performance is only applied to scales smaller
than 1:25,000. Is this possible in QGIS? 

 

Thanks for helpful answers! 

 

Kind regards 

 

Julian Schall

Re: [Qgis-user] GIS.lab Web 0.4 demo

[G. Allegri]

Andrea,
I haven't tested it, I've just given a loook to the web app code (which is
a Django application). It seems quite generic to be adapted to other WMS
infrastructures, but I would let Ivan confirm it or not.
What I was saying is that it's totally different from QGIS Web Client. The
same technologies, but the web client implementation doesn't share anything
with QWC. Right Ivan?

Re: [Qgis-user] Problem updating qgis-dev

[Alexandre Neto]

Hello,

I have regular internet connection problems, therefore incomplete downloads
were  making my qgis-dev daily update process miserable...

I found out a workaround tho.

I use wget do directly download the qgis-dev package (that preforms resumes
in case of internet connection is lost):

http://download.osgeo.org/osgeo4w/x86_64/release/qgis/qgis-dev/

And copy it to my temporary files instalation folder (normally with a name
like http%3a%2f%2fdownload.osgeo.org%2fosgeo4w), inside the respective
subfolder

After that I run osgeo4w-setup.exe choosing install from internet. Since
the package is already there the installer just checks it's integrity and
install it.

Hope this helps,

Alexandre Neto

>Many clients, deeply different from each other, adopt this technology stack...

If this is true this mean that this portal is usable ONLY wth qgis-servers ?
So no chance to use it with other products rather than QS ?

This also mean that this product is unuseful (exactly as the other)
for who has in its infrastructure product differents from qgis-server.

Of course , one could choose to change its infrastructure and move its
WMS/WFS server  to a QGIS-Server product.

Thx GioHappy,

Andrea.

Re: [Qgis-user] TAB file export

[Zoltan Szecsei]

Hi Brett,
If you can create MID/MIF, just open the mid file in a text editor and 
check that the number of lines is the same as the number of features in 
your shapefile.

If yes, then you should have all your elements.
Then simply convert the MID/MIF to TAB

It's a 2-step solution, but it should get the job done.

On the other post regarding the changing EPSG code, check the beginning 
of your MIF file to see if it is "wrong" there already (MIF is also a 
text file)

If so, it may be BUG-reporting time.

I am assuming that your shapefile has a PRJ file, or in QGIS you have 
set the correct projection/CRS


HTH,
Zoltan

AFAICS the technological stack is the same as QWC: Openlayers, Extjs,
Geoext., but it's a quite generic common denominator. Many clients, deeply
different from each other, adopt this technology stack...

Re: [Qgis-user] TAB file export

[Brett Adams]

Thanks Bo,

 

Interesting outcome.  I'll have to watch out for the projection change.

 

Looks like I'll have to accept that it's time to update.  2.4 is soon to be
released. Time to make the jump.

 

Thanks for your feedback.

Brett -

I've opened your shape file in QGIS and afterwards saved it as a tab file -
without a hitch. I'm using a newish version 2.3 of QGIS. 
I've opened the new tab file in MapInfo and it works. The only strange thing
is, that the projection shifts from EPSG:28351 to EPSG:32751 

Tabfile attached

Re: [Qgis-user] Error with QGIS Server on Debian wheezy

[Andrea Peri]

My bad
I do a rapid test and on windows it seem to work.

I surely had some troubles when move a qgis project from a windows
machine to a linux server.
The relative paths seem don't work correctly.
This was experienced in the qgis 2.0 version.

I don't explore more and choose the rapid and easy solution to change
manually the
paths in the file (with a script obviously).

From that time I do no more tests.

I see now it seem to work, but I donnot any test moving the project on
server side.
So perhaps the problem is on Linux..
I do some other test.

Regards.

Re: [Qgis-user] Error with QGIS Server on Debian wheezy

[Marco Hugentobler]

Hi

The server normally detects the relative path and expands it to an 
absolute one internally.
I just tested a project with relative pathes containing a shape and a 
spatialite layer and it worked fine here (tested with QGIS 2.2 / current 
master / Enterprise worked in all cases).



Regards,
Marco

Hi,

I have found an explanation for my problem:

Although in my project the path to Shape-File is stored relative, QGIS 
Server interpreted the path as an absolute path.


Example out of the project file:

./TestShape.shp

Therefore the shape file is not found.

With an symbolic link in root-directory, everything works.

Is this problem known?

Is there any better workaround?

Thanks,

J. Zedler

*Betreff:* [Qgis-user] Error with QGIS Server on Debian wheezy

Hi,

I need some help, running QGIS Server 2.2.0 on Debian wheezy.

Using QGIS-Projects with Datasource Postgres works fine.

Using QGIS-Projects with Datasource Shape-File didn't work.

The same Project on Windows (also QGIS Server 2.2.0) works.

GetCapabilities-Request gives all but no info for Shape-Layers

Output on stderr: ERROR 10: Pointer 'hDS' is NULL in 'OGR_DS_Destroy'

GetMap-Request crashes with Segmentation fault

The Debian-Server is installed without X-Server Packages.

Is there any idea, what's going wrong?

Regards

J. Zedler
