No problem, I do check the returned data source object. I just thought it inconsistent with GDAL. Thanks for the reply, Luke -Original Message- From: gdal-dev-boun...@lists.osgeo.org [mailto:gdal-dev-boun...@lists.osgeo.org] On Behalf Of Ari Jolma Sent: Thursday, 21 October 2010 5:00 PM T

[gdal-dev] loading a patch

2010-10-21 Thread Matt Hanneman
I noticed that gdal_translate and gdal_merge both cause the output image to be shifted by 1/2 a pixel SE. I assume this is how gdal handles the cell reference, but I am not sure. Anyways, I found a potential patch here: https://trac.osgeo.org/gdal/ticket/2637 ...but I have no idea how to apply

[gdal-dev] OCI driver supports DeleteLayer but reports otherwise

Hi everyone Just did a svn checkout https://svn.osgeo.org/gdal/trunk/gdal gdal The OGR/OCI driver seems to have a functional ::DeleteLayer but does not report this as a capability. Therefore, it will not respond to ogr2ogr -overwrite either. However the SQL command DELLAYER is understood,

For those interested in this saga, with the help of Brent, the issue has been solved and is now fixed in trunk. This was an issue when dealing with multiple georeferencing bounding boxes in Adobe style encoding and/or when the bounding box doesn't cover the whole page area. Le mardi 19 octobre

Jukka, Yes, I believe I have a workflow to do what you want. Let that your full resolution be foo.tif Put the first level of overview in foo.tif.ovr The second level of overview in foo.tif.ovr.ovr And so on You can check with gdalinfo foo.tif that the overviews are all taken into account. If yo

[gdal-dev] opening LRIT files

2010-10-21 Thread Ricardo Filipe Soares Garcia da
Hello all I'd like to know if it is possible to open LRIT[1] files using GDAL. The files I'm trying to open come from the GOES12 satellite. I investigated the MSG[2] driver, which uses a XRIT decompressor library, thinking I might be able to fool GDAL into opening my LRIT files as if they were HR

Peter, Thanks for your comments. I did not mean to suggest that GDAL produced different pixel values or statistical values than ArcGIS. In my experience, they are the same (barring this GDAL bug that I found http://trac.osgeo.org/gdal/ticket/3151 a while back, which has since been fixed). > W

thanks for that Frank, mounting a windows share folder with samba I can see the Overviews. Copying the same files into a ext4 FS, the overviews are not detected. So I renamed the .rrd and .aux files in undercapital (same name as the raster folders) and now I can see the overview also under ext4.

[gdal-dev] Query regarding results from ExecuteSQL and the OCI driver - pre OGR 1.8.n

Dear Team, I'm waiting for 1.8 to be firmed up before upgrading to it, so this relates to the old OCI driver. I'm puzzled. In order to work around the possibility that a table may not exist, and therefore require to be created, I attempted to use ExecuteSQL through the OCI driver wi
