Construct basic landscape layer data for Dynamic TOPMODEL run
Given an elevation raster this function will create a basic multi-band raster that can be used to run Dynamic TOPMODEL after applying a suitable discretisation. It comprises the supplied elevations with the addition of upslope contributing area and topographic wetness index (TWI).
Elevation raster using a projected coordinate system (e.g UTM) and regular grid spacing. Should have a resolution of a least 30m for the TWI to be meaningful.
If TRUE (default) then run a sinkfill before calaculating the upslope area and TWI.
Threshold intercell slope to determine sinks (degrees).
A multi-band raster (stack) comprising, in order, the elevations, upslope area and topographic wetness index values.
