047] How to Correct DEM Elevation Values in Global Mapper (Scale, Offset & Power)
Adjust Digital Elevation Model (DEM) values using mathematical formulas to emphasize terrain features or normalize data. Although DEM elevation correction is not commonly required, it can be useful when you need to exaggerate terrain differences for visualization or design purposes. especially when maximizing elevation differences in flat contours for design purposes. This tutorial covers how to modify an entire layer using Scale Factors, Offsets, and Elevation Power, as well as how to manage valid elevation ranges and invalid data replacement. While it doesn't happen often, there are rare cases where you need to correct the elevation of DEM (Digital Elevation Model) data. This technique is especially useful when flat terrain appears visually weak and you want to emphasize elevation differences in maps or 3D terrain models. In Global Mapper, there are methods to correct DEM data by either adjusting the entire layer...
