pDEMtools
Conveniently search, download, and process ArcticDEM and REMA products
pDEMtools provides a convenient set of functions to explore, download, and preprocess high-resolution DEMs of the polar regions from the ArcticDEM (Porter et al. 2022; 2023) and Reference Elevation Model of Antarctica (REMA; Howat et al. 2022a, b) products, courtesy of the Polar Geospatial Center (PGC).
The first aim of pDEMtools is to enable access to ArcticDEM and REMA mosaics and multitemporal strips using the search() function and load module:
search(): This function aims to allow users to easily query the PGC STAC API to find relevant ArcticDEM and REMA strips for their areas of interest.load: This module provides simple one-line functions to preview and download strips and mosaics from the relevant AWS bucket to anxarrayDataset.
The second aim is to provide (pre)processing functions specific to the sort of uses that ArcticDEM and REMA users might want (e.g. a focus on ice sheet and cryosphere work), as well as the particular strengths of ArcticDEM and REMA datasets (high-resolution and multitemporal). Tools include:
- Terrain attribute derivation (hillshade, slope, aspect, various curvatures) using a 5x5 polynomial fit suited for high-resolution data.
- Quick geoid correction using BedMachine source data.
- Simple coregistration for quick elevation change analysis.
- Identifying/masking sea level and icebergs.
Rather than introducing custom classes, pDEMtools will always try and return DEM data as an xarray DataArray with geospatial metadata via the rioxarray extension. The aim is to allow the user to quickly move beyond pDEMtools into their own analysis in whatever format they desire, be that xarray, numpy or dask datasets, DEM-specific Python packages such as xdem for advanced coregistration or richdem for flow analysis, or exporting to geospatial file formats for analysis beyond Python.

When using ArcticDEM and REMA products, please cite the datasets appropriately and acknowledge the PGC.
Several algorithms implemented in the library were developed by others. These will be highlighted in the documentation, and the original authors should be properly cited when used. For example:
We masked sea ice and melange following the method of Shiggins et al. (2023) as implemented in pDEMtools (Chudley and Howat, 2024).
