This lesson explains how to use the Viewshed Exploratory Analysis tool to quickly determine outward visibility from a known location using ArcGIS Pro.
Interactive viewsheds are used to determine the visible areas of a 3D view from a given viewpoint. For example, you might need to place security cameras to monitor a park, film cameras throughout a sporting event, or police officers around a political rally. In all these cases, you want to optimize their locations to avoid missed coverage and reduce areas with double coverage.
In our example, we’ll be determining visibility from ground level within an empty lot and at a neighboring mid-street crossing. The viewshed will reflect green for anything that can be seen from the observer point, magenta for anything it cannot see, or yellow for anything that is seen by more than one viewshed.
In this short video, you will learn how to:
• Interactively place one or more viewshed observers
• Resize, rotate, and reposition a viewshed using its interactive handles
• Use the C key to quickly navigate without changing active tools
After watching this lesson, you might be interested in other lessons in the series that cover other Exploratory Analysis tools in more detail.
