xDEM aims at making the analysis of digital elevation models easy, modular and robust.
Announcement
xDEM v0.1 is released, with all core features envisioned at creation 4 years ago 🎉!
We are merging efforts with demcompare to combine the best of both tools into one!
We are working on adding a dem Xarray accessor with native Dask support for 2025.
xDEM is tailored to perform quantitative analysis that implicitly understands the intricacies of elevation data, both from a georeferencing viewpoint (vertical referencing, nodata values, projection, pixel interpretation) and a statistical viewpoint (outlier robustness, specificities of 3D alignment and error structure).
It exposes an intuitive object-based API to foster accessibility, and strives to be computationally scalable through Dask.
Additionally, through its sister-package GeoUtils, xDEM is built on top of core geospatial packages (Rasterio, GeoPandas, PyProj) and numerical packages (NumPy, Xarray, SciPy) to provide consistent higher-level functionalities at the interface of DEMs and elevation point cloud objects.
