Digital Elevation Models : A Guidance Note on How Digital Elevation Models are Created and Used - Includes Key Definitions, Sample Terms of Reference, and How Best to Plan a DEM-Mission

Digital elevation models (DEMs) represents the elevation of the earth’s surface in the form of a digital image where each pixel contains an elevation value of the center point of the pixel. DEMs are a primary input to any modeling or process quanti...
