Supplementary datasets

To make the most of pDEMtools, two supplementary datasets must available locally:

ArcticDEM/REMA strip index

The first is the ArcticDEM or REMA strip index made available by the PGC (in GeoParquet format), used by the search function. Strip index GeoParquet files can be downloaded from the PGC (Greenland, Antarctica). To enable rapid searching, please download the GeoParquet file format: these files end in _gpqt.zip. Unzip them before use.

BedMachine

The second is the Greenland BedMachine (v5; Morlighem et al. 2022a) or Antarctica BedMachine (v3; Morlighem et al. 2022b), which is the default geoid/bedrock mask used by the geoid correction and coregistration functions (NB: for applications outside of the ice sheets, it is possible to use your own geoid/bedrock mask). BedMachine can be downloaded from the NSIDC (Greenland, Antarctica).
