Chap 5
Chapter 4 is about learning how to work with spatial databases and databases. For 4.1, I could not put YouthPopulation.gdb as an Output Feature Class. It told me that the folder was empty, so I could not include it or change the name. But when I ran the geoprocessing, I still ended up with the same result that the GIS tutorial textbook showed. 4.1 also wanted me to change the outline for MaricopaCounty and Tracts. But when I found the option for outline width, a big grey shape covered up my screen.
I wasn’t able to complete all of 4.2; it was hard to modify the tables. And my validate join was invalid, so I could not get Pop youth to join the Tracts feature class.
I am unable to save the expression “qryDateRange”. I could not find an option for expression under the Select by Attributes tool. So this means I was not able to then reuse a saved query to create a definition query.
Building the commands for the queries was slightly tedious, but rewarding.
5.1 explored how to use geographic coordinates. Some things I had to troubleshoot, like under “Projected Coordinate System,” when I double-clicked the folder, nothing happened, so I was not able to click “Hammer-Aitoff (world)”. But then when I saved the project, exited and then opened it again I was able to double-click.
5.2 was about US map projections. Changing the coordinate system was fun and very easy to follow!
5.3 explained how to set projected coordinate systems
Chap 6
For 6.2, I don’t have the option for “UpperWestSideStreetsForGeocoding” when using the Pairwise Clip tool for this section.
I found that sometimes it was very difficult to find and navigate through certain tools.
Chapter 6 mainly helped me become more familiar with the Pairwise tools, streets, study areas, and data within different boundaries.
