Fathom - Global Digital Terrain Model sets a new standard for multi-source global terrain data, offering a seamless blend of satellite and LiDAR data to provide the best available elevation information for every location in the world. Comprising consistent elevation data and comprehensive metadata it ensures access to the most recent terrain information. Available at 1-arcsecond (~30 m) worldwide and up to 1/3-arcsecond (~10 m) in areas where we have enhanced data, its capability to provide 'bare earth' elevations makes it versatile and suitable for a wide range of use cases, including the planning of linear assets, mapping natural perils, and creating artificial digital environments. This dataset is likely the most accurate DEM ever developed for flood inundation modeling.
