Module 3: Visibility Analysis

Until reasonably the data used and map produced have been 2-dimensional, here in module 3 we explored data in a 3-dimensional space. Assigned four Esri web course, 

• Introduction to 3D Data
• Performing Line of Sight Analysis
• Performing Viewshed Analysis in ArcGIS Pro
• Sharing 3D Content Using Layer Packages

The first lesson, Introduction to 3D Data, explored the basics of 3-dimentional data with an overview of vertical coordinate system. The next two web course provided step by step instructions on performing line-of-sight and viewshed analysis with ArcGIS Pro and finally wrapping up with a course on sharing 3D content. 

Some best practices when authoring a 3d scene:

• Be sure to have all source data and scene in the same coordinate system.
• Structure the content and decide what needs to be seen
• Define and area-of-interest (AOI) for the scene
• Set the required 3D symbology for the feature layers being publish
