Re: [gdal-dev] GDAL Python bindings disables setting a non-zero exit code
2012/9/27 Luke Pinner pinner.l...@gmail.com Thanks Jason, it's definitely GDAL. The order doesn't matter and I've checked ERRORLEVEL v. %ERRORLEVEL% (see below). I don't think it's related to the batch file which is just a minimal test script. The issue occurs with every Windows python script I've written that imports gdal - i.e sys.exit(anything 0) will always set an exit code of 0 if gdal is imported. Running python from the command prompt does the same thing. set pycmd=python -c from osgeo import gdal;import sys;sys.exit(1) echo %pycmd% %pycmd% if ERRORLEVEL 1 ( echo ERROR LEVEL is 1 or greater ) ELSE ( echo ERROR LEVEL is incorrect ) echo ERROR LEVEL=%ERRORLEVEL% Interestingly, one of the users of my code who originally reported the issue to me found that that ERRORLEVEL is set correctly in Windows XP. Yes Luke I made another check exluding MetaGETA imports, the software using GDAL python bindings, an it really seems related to GDAl, at least the GDAL release shipped with MetaGETA.

[gdal-dev] Gdaltindex with -t_srs and Mapserver
Hi, I had a try with gdaltindex and the new -t_srs option that is discussed in http://trac.osgeo.org/gdal/ticket/4773. It seems to be as Even was thinking in the very beginning and Mapserver does not work with tileindex which is containing reprojected bounding boxes. Images with BBOX in the native projection are shown but not the others. This line appears into Mapserver log: msDrawRasterLayerGDAL(): Error in overlap calculation. It might indeed be good to emit a warning about Mapserver incompability. It would be very nice if Mapserver supports this kind of tileindeces. -Jukka Rahkonen- ___ gdal-dev mailing list gdal-dev@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/gdal-dev

This would imply that MapServer takes into account the SRS of each GDAL dataset, which AFAIK it ignores right now to use only the SRS indicated in the LAYER (but it has been quite a long time since I configured a MapServer mapfile, so I might be wrong), to do the needed on-the-fly reprojection -Jukka Rahkonen- ___ gdal-dev mailing list gdal-dev@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/gdal-dev ___ gdal-dev mailing list gdal-dev@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/gdal-dev

Jukka, nice that you noticed this new feature I added - was about to advertise it here! The goal of adding this feature was not to make it available in mapserver, but for using in desktop applications as a reference for multiple files with different projections (e.g. landsat archives). cheers Etienne On Thu, Sep 27, 2012 at 6:07 AM, Jukka Rahkonen jukka.rahko...@mmmtike.fi wrote: Hi, I had a try with gdaltindex and the new -t_srs option that is discussed in http://trac.osgeo.org/gdal/ticket/4773.

Re: [gdal-dev] Gdaltindex with -t_srs and Mapserver
Hi, I did not meant to underestimate this little but extremely useful improvement. However, you made me hungry: if you can see so simply the image footprints, why not also the images? I am already publishing in our WMS also the tileindex shapefiles so people can see the image boundaries and make GetFeatureInfo queries from the image metadata that we have added to the shapefile as a few extra fields. In order to make it works we have reprojected images from their original projection zones into one common zone. Now I wonder if it could be possible to make Mapserver to support tileindex layers containing source images with mixed projections. As a non-programmer I have a strong belief that if I can say what I want, someone can program it. I believe that Mapserver already gets the correct image list from the mixed-projection shapefile. I guess also that Mapserver does not read image metadata from the geotiff image files for getting the projection but it relies on the LAYER level PROJECTION setting. In my simple test case with two images, one in EPSG:2393 and another in EPSG:2392 this means that Mapserver thinks that images are 1000 kilometers apart and sharing the EPSG:2393 system that I used in the PROJECTION block. Perhaps there could be an optional setting for LAYER level PROJECTION, both for individual images and tileindex layers, something like init:internal_metadata. It would mean that Mapserver would do first a query in a same manner than gdalinfo and ogrinfo for reading the native projection of the dataset. Ok, once written this long I started to think about using PROJECTION AUTO and then I found this three-year-old RFC http://mapserver.org/development/rfc/ms-rfc-37.html +1 for implementing it. By the way, woudn't it be nice if desktop GIS like QGIS would show you also your Landsat archive images and not only the footprints in some pretty automatic way, let's say, after ticking a check box and setting the maximum scale denominator value? -Jukka Rahkonen- -Alkuperäinen viesti- Lähettäjä: Etienne Tourigny [mailto:etourigny@gmail.com] Lähetetty: 27. syyskuuta 2012 15:27 Vastaanottaja: Rahkonen Jukka Kopio: gdal-dev@lists.osgeo.org Aihe: Re: [gdal-dev] Gdaltindex with -t_srs and Mapserver Jukka, nice that you noticed this new feature I added - was about to advertise it here!

[gdal-dev] SetColorTable() issues on GTiff with python bindings
Hello,
I would like to add a Colortable to a GeoTiff. Running the SetColorTable()
function, python returns 3. GetColorTable() returns empty, no colortable
is attached.
After browsing the internet for a solution, I tried to run the procedure on
a newly created GTiff (which was often suggested). Probably any issues with
the colortable?
The file is not Write-protected or problematic otherwise, WriteArray() for
example works without any problem.
ds2=dr.Create('C:\\testfolder\\X.tif',ds.RasterXSize,ds.RasterYSize,1,gdal.GDT_Int16)
ct=gdal.ColorTable()
ct.CreateColorRamp(0,(178,223,138),5,(255,127,0))
outband=ds2.GetRasterBand(1)
outband.SetColorTable(ct) # returns 3
Versions:
python 2.7
gdal 1.9.1
Any Suggestions?
Thanks for your help

You should have seen the following error emitted in the console :
SetColorTable() only supported for Byte or UInt16 bands in TIFF format. . The
data type asked in Create() is Int16, not Byte or UInt16.
