Module 3- LIDAR Visibility Analysis

 In this week we had to take a course on ESRI for Visibility Analysis. We took four courses within the activity: Introduction to 3D visualization, Performing Line Sight Analysis, Performing Viewshed Analysis in ArcGIS Pro, Sharing 3D Content Using Scene Layer Packages. 

In the first course, Intro to 3D visualization we learned how z values can represent elevation adn will allow us to see a 3D image. We used the provided data to navigate and investigate a 3d scene of Crater Lake in Oregon.

In Performing Line Sight Analysis we learned about line of sight. We used the Construct Sight Lines tool to create sight lines from an observer point. After we used the Line of Sight tool that tells you the visibility along the sight lines we just created. 

In Performing Viewshed Analysis in Arcpro we used the Viewshed tool to see waved based items by adjusting refractivity coefficients. This tools let us see streetlight cover, and how buildings can be effected by terrain. 

In Sharing 3d content we learned how we can upload our data to AGOL to share with the public, or organizations
