Awesome-DEM

This repository offers a curated list of Digital Elevation Model (DEM) datasets and related resources. It begins with an introduction that clarifies the distinctions between DEM, Digital Surface Model (DSM), and Digital Terrain Model (DTM), which is crucial for understanding elevation data types.

The core of the resource is its extensive list of data, categorized by scope and accessibility. Users can find global open-source DEMs like ASTER GDEM, SRTM DEM, NASADEM, ALOS World 3D-30m, Copernicus DEM, MERIT, FABDEM, and TanDEM-X. There are also sections for global proprietary DEMs, global open bathymetric data (e.g., ETOPO1, GMRT, GEBCO, SRTM15+), and local open datasets covering regions such as Europe (EU-DEM, EU-DTM), the US (3DEP), the Arctic (ArcticDEM, REMA), Australia (Elvis), and France (Litto3D, RGE ALTI).

Beyond data, the repository includes valuable links to papers, portals, and discussions related to DEMs, making it a central hub for researchers and practitioners seeking elevation data and information. This structured approach helps users efficiently navigate the diverse landscape of available DEM resources.
