Week9_Buffering & Overlay


This map utilized buffering and overlay to determine potential campsite areas in a state forest. It was a fun lab using the different tools. Straight forward as always. Usually get sidestepped by "user error"!

Q1. I used Intersect tool and found no differences in the results.

Q2. I used Erase to remove the conservation areas falling within the buffers_union.

Q3. There are 79 features in the possible campsite areas layer. Square meters created huge numbers and who can relate? In kilometers the largest feature is 7.765 km2 and the smallest is .00075 km2 (also hard to relate). So, I also chose to look at the areas in acres. The largest feature is 1918.774 acres and the smallest is 0.185 acres.
