| Video Discription | #Digitalelevationmodel #DEM #USMANGEO #earthscience A digital elevation model (DEM) is a 3D computer graphics representation of elevation data to represent terrain, commonly of a planet (e.g. Earth), moon, or asteroid. A "global DEM" refers to a discrete global grid. DEMs are used often in geographic information systems, and are the most common basis for digitally produced relief maps. While a digital surface model (DSM) may be useful for landscape modeling, city modeling and visualization applications, a digital terrain model (DTM) is often required for flood or drainage modeling, land-use studies,[1] geological applications, and other applications,[2] and in planetary science. #GIS GIS Open Course Ware | Geographic Information System https://www.youtube.com/watch?v=brUtxEeiuwE&list=PLM5_LnEDOfT48iE5A9rmI8cCTAuG-ZTpQ&index=1 Geological Orientation Data From Surfaces in ArcGIS |GIS analysis of geological surfaces orientation https://www.youtube.com/watch?v=ZRr0BwOuUlk&list=PLM5_LnEDOfT48iE5A9rmI8cCTAuG-ZTpQ&index=2 |
