Chapter 7
Chapter 7 opens by discussing the importance of 3D WebGIS applications. After the introduction it moves into the “Basics of 3D GIS. It emphasizes how crucial web scenes are to providing advantages with data interpretation, as well as visual interpretation of the map itself. It was really interesting to learn that 3D features include things like x-ray and radar vision, which is something that I did not even realize would be a feature. It was really cool to read about all the different tools that allow you to create and customize 3D layers like the category layer or Integrated mesh scene layers. It was also to learn that ArcGIS offers 3 suites specifically for 3D scenes. As I have a special interest in urban planning and city design the ArcGIS CityEngine was really good to know about. The inclusion of the layers that add things like trees, park benches, etc, reminded me of the final few chapters of 291. An idea that I had for an application for this chapter was mapping the population of undergraduate students by the county they live in. I would create this through a Cartographic scene, showing the population density by county.
