Re: [gdal-dev] Trouble with GPKG and colors

Hi Even, Thanks for you prompt answer! Could you please point out a valid example on how to read/write a single byte raster dataset (preferably with a color table) in GPKG with any supported setup (tiling, format, padding etc)? GTiff also can store different band count, padding, etc, but there i

[gdal-dev] Trouble with GPKG and colors

Hello, I'm trying to save a byte raster to a geopackage. I ran into a problem that the geopackage raster driver does not behave as expected when working with bytes and color tables. I have written a python script that explains the issue (attached): The script creates 4 rasters in similar ways but

Re: [gdal-dev] Error: Unable to export GeoTIFF file with different datatypes per different bands. All bands should have the same types in TIFF.

Even, Thanks for the info. I guess in that case using the highest bit depth will have to do. Regarding the nodata value (just curius): how is this value stored (there is no such tag, AFAIK)? In the GDAL data model this value is per band and not per dataset, so that could be a possible improvement

Hi list, I just tried to convert a Cloudsat (2B-GEOPROF to be exact) to a TIFF. I try to do this using the Python bindings and creating a VRT [3] referencing the Subdatasets of the HDF 4 file. When I try to do this, I get the following error: "Unable to export GeoTIFF file with different datatyp
