This week's module involved completing select courses from the "Get Started with Visibility Analysis" Esri Learning Plan. I learned the difference between the different elevation types (on ground, relative to ground, and absolute height) from the "Introduction to 3D Visualization" course. The course also offered examples of extrusion types for 3D symbology, such as polygon features being extruded vertically to represent buildings.
The "Performing Line of Sight Analysis" course listed the inputs required for performing a line of sight analysis, and described the workflow for doing so. The image below is one of the example images used in the course, where the green lines represent areas that are visible, and the red lines represent areas not visible. The course also described how to use the Construct Sight Lines and Line of Sight tools.
The "Performing Viewshed Analysis in ArcGIS Pro" course describes how to create an output raster that represents the visible area from an observer point, similar to the previous course. The main difference between the two analyses is that the Line of Sight analysis determines obstructed and unobstructed view along a line, and the Viewshed analysis symbolizes an area as visible or not visible. This course instructed me on how to use the Viewshed tool.
The final course, "Sharing 3D Content Using Scene Layer Packages" mainly taught me how to create and use Scene Layer Packages.
