I have a raster file (.tif) of different ecosystem types (from natureserve). Each value corresponds to a different type. I'm trying to get a table of those attributes and colors. The file includes (what looks like) an attribute table with a color map in a .tif.aux.xml file.
Opening the xml file in a text editor shows entries such as: GDALRasterAttributeTable tableType="thematic". and then rows and rows of the different raster values and their attributes.
How can I open this in QGIS or convert it to a format I can use?
