ILWIS -- Raster Map

Driver short name


Driver built-in by default

This driver is built-in by default

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 ilwis.
