Chapter 1
Chapter 1 introduced me to the fundamentals of ArcGIS Online and how Web GIS allows data, maps and applications to be shared and accessed by any individual around the world. I was able to learn how to create a feature layer from a CSV file, add attachments and even build a web app using the Attachment Viewer template. Web GIS is powerful because it makes mapping both interactive and collaborative, with advantages like easy access, cross-platform compatibility and low maintenance. I have also learned about the key components of a web map that are basemaps, operational layers, and tools, which work together, making information functional, clear and visually appealing. 
Chapter 2
Chapter 2 was all about smart mapping and storytelling. I learned how to publish feature layers using geocoding, style them using smart mapping, and enhance pop-ups with Arcade expressions, charts, and images. This chapter also presented ArcGIS StoryMaps which integrate maps, text and multimedia for telling spatial stories. The use of sidecar and swipe blocks enables users to explore relationships and change over time making data easier to understand. I liked how smart mapping can reveal patterns like population changes or housing trends without needing to analyze each data point manually.
Application Idea
One potential application I’d like to do is a StoryMap called Hilliard Growth and Green Spaces. It would showcase how Hilliard, Ohio, which is where I am from has grown over the years by highlighting new housing areas, schools and parks. This would include photos of local parks and pop-ups with graphs showing population growth. I could also do a section on Ohio Wesleyan University where I can map out key campus buildings and green spaces and using a swipe block to compare how the layout of campus has changed with time. This would help in visualizing community development and environmental balance here in Central Ohio.
