Visibility Analysis Mod03

This week the assignment was to complete four ESRI courses: Introduction to 3D Visualization, Performing Line of Sight Analysis, Performing Viewshed Analysis in ArcGIS Pro, and Sharing 3D Content Using Scene Layer Packages. 

In the Introduction to 3D Visualization course introduced using 3D data visualization in GIS. You can visualize 3D data in a map view, local scene view, or a global scene view. When visualizing 2D features in a 3D scene you must determine how to draw the features in relation to the ground source. Cartographic offset and vertical exaggeration are tools used to manipulate height variables. 

The Performing Line of Sight Analysis focused on how to use the Line of Sight tool to perform an analysis. The tool determines the visibility along sight lines given terrain. This is represented by the input surface, and obstructions which are represented by the input features.

The Performing Viewshed Analysis in ArcGIS Pro covered the Viewshed tool in ArcGIS. This tool creates an output that models the areas that are visible form given vantage points. The course taught how to modify the input features to model the visibility from a known vantage point. From the fixed vantage point you can evaluate the visibility of the entire area.

The Sharing 3D Content Using Scene Layer Packages went over the benefits and requirements of sharing 3D data. You must have privileges to publish hosted scene layers, these privileges also include creating content. You must ensure the box next to publish this file as a host layer is checked or a scene layer will not be published.
