The first chapter of this book starts by explaining some of the benefits of having GIS on a web-based platform- such as increased interactions, wider access, and easy use. I also learned what HTTPS, HTML, and URL stand for (abbreviations we all use every day but probably don’t know what they actually mean). The first chapter also goes into a lot of technical explanations about the geospatial cloud capabilities- which didn’t make a ton of sense to me, but it was still interesting to see how widely available Web GIS is. It was interesting to learn about the history behind web GIS websites and how they used to be all separate before the 1990s, which made it incredibly difficult to share information with others. Once the internet and web became more sophisticated in the late 1990s, GIS applications became much easier to view, use, and share. It was also interesting to read about how Web GIS uses AI and machine learning currently. These chapters also go over some of the content involved in ArcGIS Online- most of which are similar to ArcGIS Pro, but the apps and web maps are a new concept (though we partially looked at some of these in 291). One very nice part about the GIS apps is that they don’t require any coding or programming- which makes them much more accessible to a wider range of people. The tutorials were all fairly easy- there was a bit of a learning curve finding where all of the things are located in the different toolbars since it is slightly different than what I had become so familiar with on ArcGIS Pro. I enjoyed creating the apps, and I also thought it was a good feature to have a preview of how the app would look on a phone, computer, etc. It was also fun getting to style some of the points in ways that ArcGIS Pro couldn’t.
One idea for an app based on the techniques used in chapters 1 and 2 would be an interactive app/ web map that would be directed toward road trippers or people traveling through the US. Routes could be drawn on the map, with stops in cities or landmarks that have interactive points with information on each location. Another application of these techniques would be to show the pollution data of various cities and even show how it has changed over time by comparing current pollution data to previous recordings (using the above and below feature). This would give us an idea of what cities have strived towards decreasing their pollutants and which have increased their pollution.
