Intro to GIS: Week 10 - Vector Analysis Part 2

In this week's lab, we learned how to utilize the buffer and overlay tools in ArcMap by narrowing down our search parameters for potential campground sites. We learned how to use ArcPy which we used to create a script to run the buffer analysis tool once or multiple times. We used spatial queries to help us analyze the vector data presence. There are six different overlay operations that can be used to combine or erase data features from analysis. Along with learning about the overlay tool, we leaned about the difference between multipart layers and singlepart layers. 

This lab was a pretty straightforward with its instructions this week. I had some fun playing with the buffer tool when creating the different buffer distances of the roads feature on the map. The six types of overlay operations made things kind of interesting as well. The union operation and the update operation highlighted different areas of the map; however, both of the operations' areas fit together like a jigsaw puzzle. Overall, this week's lab was pretty fun to work on for class.
