# ILWIS -- Raster Map

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.

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`.
