#73: r.out.gdal tiff output does not work -----------------------+---------------------------------------------------- Reporter: helena | Owner: [email protected] Type: defect | Status: new Priority: critical | Milestone: 6.4.0 Component: default | Version: svn-trunk Resolution: | Keywords: r.out.gdal, tiff -----------------------+---------------------------------------------------- Changes (by mlennert):
* priority: major => critical Comment: We've been having similar problems here and I've tested a bit further with current svn. At http://geog-pc40.ulb.ac.be/grass/misc/r_out_gdal/ you can find relevant files: - test_loc.tgz: test location with one raster file - test.tif: this same raster file exported with 'r.out.gdal type=UInt16' - test_tiffinfo.txt: tiffinfo output on test.tif (note the errors at the beginning) - test _gdalinfo.txt gdalinfo output on test.tif, which shows the correct color categories and then an all-black color table from 0 - 65535. Is it normal to have both 'COLOR_TABLE_RULE_RGB_0' entries and a color table in the tiff ? The tif can be read and displayed by QGIS. SAGA gives a weird image (both with band and pixel interleave): test_saga.png. gvSIG crashes when trying to load the file. These are not some general picture viewer, but cartography/GIS programs, so I would hope that we should be able to solve this for reasons of interoperability. Final test which seems to show that there is something wrong: r.in.gdal in=test.tif out=test: import takes a very long time and creates a huge colr table file: % 0 65535 0:0 1:0 2:0 3:0 4:0 5:0 6:0 7:0 8:0 9:0 10:0 11:0 [...] 65535:0 65535:0 Whereas the original colr file only contains this: % 334 460 334:0:191:191 359.2:0:255:0 359.2:0:255:0 384.4:255:255:0 384.4:255:255:0 409.6:255:127:0 409.6:255:127:0 434.8:191:127:63 434.8:191:127:63 460:20 The display of test also takes a long time, I suppose because of this long colr table. I'm moving this up to critical as I think this is a fairly basic feature which should "just work"...
