Digital Elevation modeling is widely used in GIS for studying geology, relief maps, land-based studies, flood modeling and similar. DEM data analysis is important for the aforementioned 3D mapping workflows. Additionally, DEM analysis forms part of 3D mapping workflows for land administration, mining and forestry applications. Surface and elevation information enables the precise location and mapping of objects that are below or under the earth’s surface. Now that assets are being modeled, positioned and mapped inside their spatial context, surface information is a necessary component for 3D mapping purposes.
