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)

Table 5: Data types used in SPHY.

data type	description attributes	domain	Example
boolean	boolean	0 (false), 1 (true)	suitable/unsuitable, visible/non visible
nominal	classified, no order	-231 ... 231, whole values	soil classes, land use classes, discharge stations, administrative regions
Ordinal	classified, order	-231 ... 231, whole values	succession stages, income groups
Scalar	continuous, lineair	-1037...1037, real values	elevation, temperature
directional	continuous, directional	0 to 2 pi (radians), or to 360 (degrees), and -1 (no direction), real values	aspect
Ldd	local drain direction to neighbour cell	1...9 (codes of drain directions)	drainage networks, wind directions
