Migrating from GDAL 1.7.2 to GDAL 1.8.0, I noticed that GDALDataset::GetProjectionRef() now returns an empty string "" on some cases where it previously returned an informative WKT string. The file I initially noticed this on was a 10Jan2009 Worldview image in NITF format. The image has 2 subdatasets, one of which (NITF_IM:1) is a 90x87 thumbnail, the other (NITF_IM:0) is an ~35k x 34k single band image.
In GDAL 1.7.2, GetProjectionRef Produced an identical string for both NITF_IM:0 and NITF_IM:1. In GDAL 1.8.0, GetProjectionRef Produces an empty string for NITF_IM:0 and the same string produced by 1.7.2 for NITF_IM:1. Any ideas as to whether this is a design change or a bug? If design change, what is the new best practice to retreive the projection for NITF_IM:0? -- View this message in context: http://osgeo-org.1803224.n2.nabble.com/GetProjectionRef-difference-1-8-vs-1-7-2-tp6024512p6024512.html Sent from the GDAL - Dev mailing list archive at Nabble.com. _______________________________________________ gdal-dev mailing list gdal-dev@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/gdal-dev
