xDEM aims at making the analysis of digital elevation models easy, modular and robust.
Announcement
xDEM v0.2 is released with support for elevation point clouds, as well as other features (see Release notes for details)!
We are finalizing a dem Xarray accessor, and refining a command-line interface to perform multi-step analysis workflows.
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.
