Preface: This was pretty self introductory and self explanatory. I felt that it gave good real world examples of how GIS is used and prepared me for what to expect in the book.
Chapter 1: This was basically how to look at maps and how to turn off and on layers, as well as how to organize them for better analysis. The examples in this chapter were maps of Allegheny County, Pennsylvania with distributions of different urgent cares and medical clinics. AT the end of the first example, it shows how to export a map to a png.
By the way the images I’m inserting are mostly the your turn activities to show that I was in fact following along!
The next example shows how to select and search different attributes. It can be done by selecting them in the attributes table or on the map.
The next examples go more in depth about organizing and viewing attribute tables. It shows how to remove different features, and more about selecting with the table. It also shows different keyboard shortcuts for selecting multiple features and how to select an area.
Then, how to summarize statistics such as mean, median, and mode. The quantile part was a little bit confusing to me. I liked how you could set it up to do multiple types of summaries at once though! Finally an introduction to the fun part, which is setting up and modifying different symbols on the maps. This part was pretty intuitive. Finally, a little about making 3d layers, but I couldn’t figure out how to scroll to see the 3d-ness effectively.
Chapter 2: All about labeling and more about symbols. There were a few nifty things about determining what pops up when you click on the map and how to make labels more readable.
More about searching by attributes. Then it talks about chloropleth maps, which is not a word in the other book. There’s a lot about balancing the data so it makes sense visually.
Finally, some about manipulating dot maps, which was pretty simple and straightforward.
Chapter 3: Yeah I had technical issues here. I couldn’t get the maps to upload nor could I get the green map in the layout tutorial to show up. The online parts were easy and I’m sure having actual maps would be nice!
