CUBIZEN: Global Mapper, CityEngine & Creative Tech

Identify high-visibility zones by overlapping multiple viewshed results to determine Viewshed frequency across a project site. This tutorial covers the concept and execution of Viewshed Frequency Analysis (Viewshed Frequency) in Global Mapper. Unlike standard viewshed analysis that looks out from one point, this method identifies how many different viewpoints can see specific parts of your site, helping planners minimize landscape impact through data-driven design. Today’s topic is Viewshed Frequency Analysis (also known as Viewshed Frequency). As the name suggests, it refers to how frequently a certain area is visible from multiple viewpoints. While standard Viewshed Analysis identifies the area visible from a specific viewpoint, Viewshed Frequency Analysis determines how many viewpoints can observe each part of the project site. Essentially, it overlays multiple viewshed layers and counts the Viewshed frequency for...

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...
