In Chapters 3 and 4, we cover sophisticated Web GIS features and uses. These increase spatial data analysis and visualization skills. Chapter 3 covers the ArcGIS Experience Builder, its features, and how to use them. It was difficult to combine and analyze the data at first, but the class taught me how to construct dynamic and interactive maps. Storytelling with 2D and 3D maps and animations adds depth and simplifies spatial information sharing. Mastering these techniques can be complex, but it allows you many choices for developing unique and useful spatial apps. Chapter 4 discusses mobile apps and AR integration and how they might improve the user experience. The course explains how easy it is to add data-collection functionality to the app by creating a survey. However, certain parts of the training were hard to navigate, possibly due to a broken software interface or a lack of directions. Despite these issues, designing mobile apps and integrating AR can help us make geographical information more accessible. Delaware Data inventory can teach us about school areas, condominium polygons, and more. This hands-on lesson teaches us about geographical data layers and their practical applications. Making a Columbus region map of car accident hotspots for the end-of-semester assignment allows us to apply what we’ve studied. We may create a robust road safety tool by integrating dynamic mapping and mobile app development from Chapters 3 and 4. To conclude, Chapters 3 and 4 explain Web GIS’s advanced capabilities and usage, which enable dynamic and interactive spatial experiences. Despite challenges, real-life research and experimentation lead to new ideas and crucial geographical data analysis and visualization initiatives.
