Free Digital Elevation Models

The days of data shortage are gone. More and more DEM data sets are published under free licenses or as public domain. Through INSPIRE in Europe more and more will follow. The datasets below are not complete. This project will focus on free high resolution datasets with a spatial resolution of 30 meters and below on county/state scale. Have a look at the OpenDemSearcher map client on this website.

For low resolution DEMs here is a great map client.

Other sources, catalogues and lists for high resolution open DEM data:

- OpenTOPO: Community lidar datasets
- LAZIP: Download free and lossless LiDAR compression data
- Wikipedia National Lidar Dataset
- Wikipedia National Lidar Dataset (United States)
- ArcGIS OpenData Catalog
- OpenTerrain List

Please read the license carefully. Not all versions of a dataset might be available for free usage.
