Doug McClune had a neat idea - visualize the level of crime in a geographic area by giving it an elevation on an otherwise two-dimensional map. The image below provides several different angles of where prostitution arrests are most likely to be made in San Francisco, which cast a surprisingly large shadow upon the rest of the city....
McClune notes:
... the prostitution arrests are peaking on Shotwell St. at the intersections of 19th and 17th. I’m sure the number of colorful euphemisms you can come up with that include the words “shot” and “well” are endless.
I love the way the mountain range casts a shadow over much of the city. There’s also a second peak in the Tenderloin (which I’m dubbing Mt. Loin).
McClune also provides topographical crime maps based on the locations of San Franscisco Police Department's arrests for larceny, narcotics, assault, vandalism, vehicle theft, robbery and warrants served!
