Chapter 3 mainly discussed the ArcGIS Experience Builder, which I found surprisingly easy to use even without much Web GIS experience. I was also pleasantly surprised at how easy it was to create both 2D and 3D maps and customize them using widgets to make them more interactive. The tutorials walked me through how to build multi-page apps and organize content visually, which was helpful. Chapter 4 dove into the mobile aspects of Web GIS, which I hadn’t realized was so advanced. The idea of GIS moving into the “post-PC era” stuck with me—it’s really crazy how much we rely on mobile devices now, and even more impressive that we can collect and analyze data directly from them. While I found it helpful in GEOG291 to learn how to use desktop GIS, this is definitely the future of this kind of software. Learning how to use Survey123 and Field Maps opened up a lot of possibilities for real-time data collection. I loved how you could easily make surveys to fit local needs and then access and analyze that data seamlessly. Additionally, I could see that the section on rapid data collection was particularly relevant for emergency response, environmental monitoring, or even community engagement projects. Overall, these chapters made me realize how much more accessible and action-oriented Web GIS can be, it really expands the user base. One way I thought of that Survey123 can be used in conjunction with a web map is to create a lost and stray animal reporting system where community members could submit details like location, photos, and contact info through a simple survey. The data would then appear on a real-time web map, helping users spot patterns and filter reports, with the goal of connecting lost pets with their owners quickly.
