CUBIZEN: Global Mapper, CityEngine & Creative Tech

In this tutorial, you will learn how to use the built-in Viewshed Creation tool in CityEngine. We will move beyond traditional 2D line-of-sight mapping to perform highly accurate 3D visibility analysis, taking into account terrain, building heights, and precise camera angles. In landscape review reports or environmental impact assessments, viewshed analysis is a methodology you will frequently encounter. Originally used in telecommunications to identify radio wave shadow areas, it has been widely adopted in landscape architecture to evaluate changes in visual obstruction before and after a construction project. Let's look at a common visual example of how viewshed analysis is typically presented. [img 1 : Traditional 2D viewshed analysis example showing red visible areas] This is a viewshed analysis conducted from position 1, where the red areas indicate the regions that are visible from that specific point. ...

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...

Learn how to incorporate 3D building data into visibility calculations for realistic urban line-of-sight mapping. This tutorial covers the essential workflow for preparing vector building data, calculating floor-based heights using attribute math, and configuring the Viewshed tool to recognize buildings as physical obstructions on top of a terrain model. Introduction to 3D Building Viewshed Analysis 🎥 Video Tutorial: Viewshed Analysis with 3D Buildings For a clearer understanding, check out the video tutorial below. It walks you through the entire process—from calculating building heights using attribute data to generating an accurate Line of Sight (Viewshed) map with urban obstructions. Follow along with the video to master this advanced technique! Video walkthrough of Viewshed Analysis with 3D Building Obstructions To follow along, please open the Workspace we worked on in the previous ...

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...
