Hello, I have a doubt: I have a raster loaded in PostgreSQL with gdal2wktraster, and I'm not sure of the best way to know the number of raster bands the raster has. The fields "pixel_types" and "nodata_values" from raster_columns table are arrays with one element per raster band, so, counting the number of elements of one of these arrays, I can get the number of raster bands. But it doesn't seem to be a very "elegant" way. Do we have another way to do this?
Thanks in advance. Best regards _______________________________________________ gdal-dev mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/gdal-dev
