Lesson 7 – Working with Terrain Data

Global Mapper offers an extensive collection of terrain or elevation analysis functionality, including contour generation, viewshed analysis, and watershed modeling. Before embarking on any of these advanced procedures, familiarity with the basic operation of Global Mapper’s 3D functionality is essential. Later in this lesson, we will explore the use of the 3D Viewer for a realistic birdseye perspective, and the Path Profile tool, which displays a cutaway view of the terrain. To begin, however, we will explore some of the options for terrain display and visualization.
