[gdal-dev] The GeoTransform Array

The GDAL API tutorial describes this array as: adfGeoTransform[0]/* top left x */ adfGeoTransform[1]/* w-e pixel resolution */ adfGeoTransform[2]/* rotation, 0 if image is "north up" */ adfGeoTransform[3]/* top left y */ adfGeoTransform[4]/* rotation, 0 if image is "north up"

Re: [gdal-dev] building overviews and ignoring NODATA?

Hi Even thanks for the info - I created a ticket (#4904) so it's not forgotten and added sprice in CC - although he hasn't seemingly been active in gdal for a few years. Etienne On Tue, Nov 20, 2012 at 8:36 PM, Even Rouault wrote: > Le mardi 20 novembre 2012 21:14:12, Etienne Tourigny a écrit :

Re: [gdal-dev] SQLite Driver and non-spatial tables

For the record, in case anyone is interested, it appears setting SQLITE_LIST_ALL_TABLES=YES appears to allow me access to non-spatial tables. I didn't find any documentation on the format page though. On Tue, Nov 13, 2012 at 1:44 PM, Kyle Shannon wrote: > I have a Spatialite enabled SQLite file

[gdal-dev] building overviews and ignoring NODATA?

Hi all, I just noticed that GDALBuildOverViews disregards all nodata pixels. While this is useful in many cases, sometimes it can be desired to NOT overlook nodata pixels. For example, I have a raster of sparse data (many nodata pixels), that I am using gdaladdo to make down-sampled versions. The

[gdal-dev] OpenJPEG 2.0 released

Hi, Just to inform you that the OpenJPEG project has just released OpenJPEG 2.0.0. GDAL users of GDAL 1.10dev that need support for JPEG2000 can (must) now rely on a released version, and no longer on the openjpeg SVN v2 branch (which has been removed by the way) Even _

Re: [gdal-dev] gdal 1.9 path problem when I using special characters

Hi, we were running into the same issues and solved it by this workaround: use Windows 8.3 filenames and paths for ECW files: // WORKAROUND for either a GDAL issue or an issue within the ECW library used by GDAL: // when opening ECW files with unicode chars in the filename or p

[gdal-dev] which formats support subdatasets?

Hi I'd like to be able to identify which raster and vector formats support subdatasets (or multipl layers). A quick grep search (grep SUBDATASETS frmts/*/*.cpp) showed which GDAL drivers can report subdatasets. Am I missing something? I think it would be nice to include this info in the driver s
