# Other static input maps

Similar as the DEM, you can reproject and resample other static model input data and convert them to PCRaster format maps using the reprojection and resampling functions in QGIS (step 1-9 from Section 5.3). Note that different data types are used for PCRaster maps. You can convert maps from one data type to another using the command line functions boolean(), nominal(), ordinal(), scalar(), directional() or ldd(). For example to convert the scalar type landuse.map to a nominal landuse.map, type:

*pcrcalc landuse\_nominal.map = nominal(landuse.map)*
