During lab this week, we learned how to use buffers and overlays to help define areas that met certain criteria. We had to find areas within the De Soto National Forest that were within 300m from roads, 500m from rivers and 150m from lakes, and that also do not fall within the designated conservation areas. The buffer tools helped to define the areas near roads and waterways. We had to join this data using the Union tool and then use overlay tool to exclude the areas within the conservation zones. To finish up, we split out each parcel and calculated the area for each, then visualizing these numbers using a gradient scale. I choose to show the possible camp site locations based on calculated area, using 5 different classes based on the data itself. I broke the groups down into up to 10ha, 10.01-50ha, 50.01-100ha, 100.01-300ha, and 300ha and above. I used a color scale from dark blue to yellow, with the darker colors representing the smaller parcels as this made them easier to see on the map. When I created the map layout, I created a polygon around the area of analysis to show in the inset map so viewers would know exactly where in the park the analysis took place.
