In Chapters 1 and 2 of Getting to Know Web GIS, I was introduced to the foundations of web GIS and how it connects with the broader digital geography ecosystem. I learned how ArcGIS Online is not only a mapping platform but a full suite of tools that supports interactive mapping, data sharing, and spatial analysis through the web. What stood out most was how easy it is becoming for non-experts to engage with spatial data through intuitive interfaces and web apps.
Chapter 1 discussed the growth and importance of Web GIS in the modern world, with examples across government, business, education, and environmental fields. Chapter 2 covered the basics of creating web maps, publishing data layers, and configuring pop-ups and symbology. I appreciated the real-world examples that showed how GIS is used to solve spatial problems and communicate stories effectively.
Application Idea Based on Chapters 1 & 2
Using the Delaware Data from Geog 291, I’d like to create a web map showing broadband access gaps across different counties. I could layer internet speed data, demographic information, and educational access points to highlight areas where underserved communities may lack reliable internet. This could be useful for policymakers or school districts trying to allocate funding for digital access programs.
