A Digital Elevation Model (DEM) is a digital model or three dimensional (3D) representation of a terrain's surface created from elevation data. The term DEM was introduced in the 1970s with the purpose of distinguishing the simplest form of terrain relief modelling from more complex types of digital surface representation The models come in two formats: Digital Surface Model (DSM; a model of the ground that includes both ground and above ground features as buildings, vegetation, etc.) or Digital Terrain Model (DTM; representing the bare Earth elevation, vegetation and man-made objects removed) Our planet is a busy place—full of peaks, valleys, natural habitats, and human-made objects. When navigating Earth's varied terrain, digital elevation data brings these highs, lows, and features into view. By providing you with a visualization of the landscape in question with elevation data, you can estimate areas most vulnerable to sea-level rise, spot vegetation encroachment, and avoid.

The resolution of DEMs varies depending on the area the pixels represent. DEMs are typically used to represent terrain relief DTD - Digital Terrain Data DEM - Digital Elevation Model DTM - Digital Terrain Model DTED - Digital Terrain Elevation Data. All of these terms are synonymous with DEM being the most commonly utilized term. DEMs stored elevation value in regularly spaced intervals. Each value represents the elevation value of that cell

ASTER data is a digital surface model produced from paris of ALSO satellite images. Whilst of reasonably high spatial resolution, 30 meter pixel size, is has a fairly low earth surface elevation accuracy which can make hydrological analysis in built-up and forested terrain problematic.

The digital elevation model is basically a 3D representation of the earth's surface or any terrain's surface, it is well known as DEM which is mainly created from elevation data. A terrain is mathematically modeled as a function z = f ( x , y ) which maps each point ( x , y ) in a planar domain D into an elevation value f ( x , y ) Digital Elevation Model (DEM) is the terminology adopted by the USGS to describe terrain elevation data sets in a digital raster form. 7.5-minute DEM (10-meter x 10-meter data spacing, cast on Universal Transverse Mercator (UTM) projection) were merged and resampled at 100-meter x 100-meter for this data set Download the Digital Elevation Model (DEM) quads file in KMZ format, then open it in Google Earth or other geographic browsers to find out what DEM files you need to download for your project.
