Week 9 - Vector Analysis II


Q1: To produce similar results to the steps used for the Union tool, I chose to use the Intersect tool. There were no noticibe differences in the output.
Q2: To remove areas in the Buffers_Union_single shapefile that overlay with the conservation_areas shapefile, I chose to use the Erase tool. This created a new shapefile of polygons of the possible sites required.
Q3: There are 4 features in the possible_sites shapefile. The largest area is 8.91 sq. meters with the smallest areas being 5.8575 sq meters.
