ILWIS – Raster Map

Driver short name


This driver implements reading and writing of ILWIS raster maps and map lists. Select the raster files with the.mpr (for raster map) or the.mpl (for maplist) extensions.


  • 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.


  • 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.
