GIS5100: Module 3 - Visibility Analysis

 

For this week's lab, we were tasked with completing learning exercises that consisted of modules and seven quizzes. Each exercise focused on different aspects and concepts concerning 2D and 3D maps and scenes. One essential new tool I learned about during this lab was Construct Sight Lines, which generates 3D lines between the observer and the target features to analyze visibility. This tool is ideal for fire tower coverage or urban planning. We also learned about the Line of Sight tool, which provides visibility along those lines. This identifies whether targets are visible or obstructed. I really liked going through the exercises and being able to learn about the software and geo-processing methods, and then being given walkthroughs on how to do things in ArcGIS simultaneously. This week's lab was a refreshing exercise that I think helped me a lot.
