Chapter 7 covered creating and navigating 3D web scenes. I learned about photorealistic scenes, which recreate real-world textures, and cartographic scenes, which turn 2D data into 3D thematic maps. It was interesting to see how different scene layers, like 3D objects and building layers, can be combined for detailed visualizations. I also explored tools like VR, AR, and indoor GIS for immersive mapping. A question I had was how large 3D scenes perform on mobile devices. Managing detail without slowing down seems important for real-world use.
For my application, I would create a 3D web scene of land use and ownership in Delaware County. Using parcel and zoning data, I would extrude parcels and color-code them by type, helping visualize patterns for planning.
