What determines whether you can open an attribute table inqGIS?. I'd like to edit an attribute table for a raster in qGIS, but it won't me open the table. There's plenty in the help about editing attribute tables, but it doesn't say when you can/can't open them

Vector data types have a table of attributes - which can be opened in QGIS. Raster datasets generally do not have table of attributes A raster datatype is a grid where each cell has a value.

  • Question is about raster attribute tables. GDAL can handle them through this class http://www.gdal.org/classGDALRasterAttributeTable.html#details but I don't know if QGIS supports RATs. – user30184 Mar 22 '18 at 08:51
