The purpose of this lab was to gain experience with more advanced model builder processes. Specifically inline variable substitution and model iterator.
Methods
A model iterator was used in order to perform a certain calculation on Slope, Aspect, and DEM rasters. This was also used with inline variable substitution to firstly create a buffer. Then zonal statistics were calculated for all three rasters. After these processes, the selection tool was used to extract the four different run types: beginner, intermediate, advanced, and expert. Figure 1 shows the model building process used to create the map shown in Figure 2.

These results shown in Figure 2 may be off by a bit. Throughout the process, many troubles were run in to. In the end the map looks correct, but it ultimately could be wrong.
