Digital Elevation Model
A Digital Elevation Model (DEM) is a raster data set that describes the terrain elevation of the survey area. A terrain-following drone can collect highly accurate data about the topography of the survey area. This raw data can then, in turn, be used to create a detailed 3D raster dataset of the survey area elevations. We can apply a number of post-processing techniques to enhance the DEM, depending on what you want to use it for, providing many ways to visualize the elevation of the features of the terrain.
