# Name: Shapefile to JSON
# Purpose: The purpose of this script is to download a zip file that
# contains a shapefile(s), unzip it, buffer where needed,
# merge all the shapefiles together into one coverage polygon,
# merge all the polygons together with a dissolve, then single
# part to multipart the results. Amounts of polygons and amounts
# of vertices will be calculated to make sure that the amounts
# are not too high, to be checked against later when scripts are
# merged.
