     84== Provide improved handling for Large Raster Attribute Tables ==
     85
     86The current GetDefaultRAT/SetDefaultRAT implementation is not suitable for large RAT's - the whole RAT must be read and held in memory. A solution would be to create a new method to return a derived class that handles the actual reading and writing much like GetRasterBand. This derived class could have methods for reading/writing parts of specified columns from/to application managed memory and handling data type conversion much like RasterIO.
