005] How to Perform Viewshed Analysis in Global Mapper for 3D Visibility Studies
Identify visible areas and calculate line-of-sight from specific viewpoints using terrain and vector data. This tutorial provides a comprehensive guide to performing Viewshed Analysis in Global Mapper. You will learn how to set up observation points, configure parameters such as observer height and view angles, and leverage Global Mapper's unique ability to include building vector data as obstructions without DEM conversion. What Is Viewshed Analysis in Global Mapper? Following our previous session, today we will dive into Viewshed Analysis in Global Mapper. Viewshed Analysis is commonly used to evaluate how a project or development affects visible areas within a landscape. It is an analytical process where you select key viewpoints and look toward the project site to compare the current status with the planned state to see how much the visibility changes. (In many real-world projects, analysts evaluate only the existing...
