gdaldem

gdaldem(dataset, method, options=String[]; dest="/vsimem/tmp", color=name|GMTcpt, kw...)

Tools to analyze and visualize DEMs.

Parameters

• dataset: The source dataset.

• method: the processing to apply (one of “hillshade”, “slope”, “aspect”, “color-relief”, “TRI”, “TPI”, “Roughness”).

• options: List of options (potentially including filename and open options). The accepted options are the ones of the gdaldem utility.

Keyword Arguments

• color: color file (mandatory for “color-relief” processing, should be empty otherwise). If color is just a CPT name we compute a CPT from it and the input grid.

• kw...: keyword=value arguments when method is hillshade.

Returns

A GMT grid or Image, or a GDAL dataset (or nothing if file was writen on disk).
