053] How to Compare Terrain Changes Over Time in Global Mapper Using Path Profile
Visualize and analyze elevation differences between two periods using multiple DEM layers. This tutorial demonstrates how to use the Path Profile tool to compare terrain data from different dates. By overlaying multiple Digital Elevation Models (DEMs), you can easily identify topographic changes and export analysis results for civil engineering or environmental monitoring projects. In this tutorial, we will compare terrain changes using two DEM (Digital Elevation Model) datasets and the Path Profile tool. The workflow is straightforward. You just need to turn on all the DEM layers you want to compare and then run the Path Profile tool. First, prepare two DEM files. img 1 : DEM data from 2024-12-01 img 2 : DEM data from 2025-01-01 Import both files into Global Mapper. img 3 : Global Mapper Control Center showing two loaded DEM layers Preparing Multiple DEM Layers for Comparison ...
