Chapter 7: This chapter briefly went over how to modify and edit maps. While this chapter didn’t provide super important information, it was still very helpful. It gave me background on how to scale and move polygons within the map. Essentially, this chapter helped me design my maps to be more visually appealing. I only ran into a few problems within this chapter. One of them is my inability to split the buildings. I drew my shape around the building and double-clicked as instructed, but the two buildings in 7-1 didn’t split. It was interesting to apply polygons to not just buildings, but parking lots, and other features as well. This taught me how useful creating a digital version of it on the map can be. Another issue that I ran into was my inability to find the bus stop marker. I don’t think this is a big problem at all because I was able to use another symbol to mark the bus stop, but I thought I would note it. For future reference, it was good to learn that I have to import features from a downloaded building so that I can modify them.
Chapter 4: This chapter was very helpful in learning how to label, organize, and combine data.I did have a few struggles within this chapter. My main struggles were in 4-1 and 4-2. In 4-1, the chapter told me to paste some of the data into a different folder so that it was available in multiple places. However, I was only able to paste one of the data sets into the correct folder. The other data set didn’t give me the option to paste it. Additionally, at the end of 4-1, the instructions told me to delete the tracts file from the geodatabase. This permanently deleted the information on that file. However, in 4-2, I needed the information on the file. I think that this is a part of the chapter that I might have to go back and redo to figure out if I messed that part up. Something that I thought was interesting was the use of parentheses to order attributes when selecting them. Another thing that I thought was interesting was the ability to select for specific attributes. While this can become a little confusing if it isn’t selected perfectly, it can be super useful when trying to narrow down the data on the map. I had some more struggles in 4-5. In this section, I struggled selecting the field in the attribute table for the neighborhoods in Pittsburgh. The book told me to select fields X and Y, but neither of those fields was an option, and I was not able to create them as an option. I also had struggles with the table in 4-6. In this table, the book wanted me to insert rows to assign categories to the crime types. However, the table wouldn’t allow me to insert any rows into it.
