ILWIS -- Raster Map
This driver implements reading and writing of ILWIS raster maps and map lists. 
Select the raster fileswith the.mpr (for raster map) or the.mpl (for maplist) extensions.
Features:
 -  Support for Byte, Int16, Int32 and Float64 pixel data types.
-  Supports map lists with an associated set of ILWIS raster maps.
-  Read and write geo-reference (.grf).
     Support for geo-referencing transform is limited to north-oriented 
     GeoRefCorner only. If possible the affine transform is
     computed from the corner coordinates.
-  Read and write coordinate files (.csy).
     Support is limited to: Projection type of Projection and Lat/Lon type that
     are defined in .csy file, the rest of
     pre-defined projection types are ignored.
Limitations:
 -  Map lists with internal raster map storage (such as produced
     through Import General Raster) are not supported.
- ILWIS domain (.dom) and representation (.rpr) files are currently ignored.
NOTE: Implemented in gdal/frmts/ilwis.
