003] How to Create DEMs and Perform Terrain Analysis in Global Mapper
Transform raw contour data into actionable Digital Elevation Models and perform detailed statistical terrain analysis. This tutorial covers the complete workflow for GIS professionals using Global Mapper, from importing topographic maps and generating DEMs to performing raster reclassification for area-based statistics and slope analysis. Today, we will learn how to create a DEM (Digital Elevation Model) and perform terrain analysis in Global Mapper using contour data. If you are accustomed to ESRI products or Q-GIS, you might find Global Mapper's output slightly different at first, but its intuitive workflow is incredibly powerful once you get used to it. 1. Importing Contour Data into Global Mapper The first step in terrain analysis is generating a Digital Elevation Model (DEM) from contour data. You can use your own data or any standard digital topographic map files. Download: Terrain_data.zip (Verified and...
