Chapter 7 mainly talks about 3D web maps, and how they can be used to create more immersive and interactive data visualizations. There are two main types of web scenes, photorealistic which is exactly what it sounds like, 3D maps that are very similar to the real world feel of an area. Conversely, there are cartographic 3D maps which are used to make a better visualization of more traditional map elements. In either case, textures, surfaces, and features of 3D web scenes can be used to help users have a better understanding of the area through more evident spatial relations and scale. I also learned about Lidar, which is a laser technology that is used for sensing and the creation of 3D maps, and how it can specifically be used to map elevations and man-made structures. Additionally, tools within Web GIS like Web AppBuilder give everyday users the ability to build web apps with widgets like Query and Filter without the requirement of coding knowledge, making data visualization and map creation much more accessible. Finally, chapter 7 discussed the growing role of more immersive technologies such as virtual reality (VR), augmented reality (AR), and extended reality (XR), as well as indoor GIS and the concept of the metaverse, this highlights how GIS is growing into more engaging, game-like digital environments. One application of a web scene environmentally could be to create a forest canopy web scene for Delaware County. Using Lidar elevation data and time-enabled layer, this type of app could help to visualize forests and green spaces in our community and their shift due to urbanization. This resource would be useful for awareness of our impact and to help with further planning.
