Nina Katchadourian is an artist who does lots of stuff with maps. The map below links to pictures of moss maps. If you click the "Next Project in Maps" you'll get lots of other interesting map art she's done.
The text below is from the original posting back in May (this is actually being written in August). It now appears that the map has been taken off the web page of La Voz de Galicia. I tried searching with my non-knowledge of Spanish using the words vertederos and mapa and all links to the map seem to be gone. Too bad because it was a good one. The original text:
Way back in 1990 I participated in a project mapping and cataloging illegal dumps in Slovenia. Here's a technologically more advanced version for Galicia in northwestern Spain. You can click on any dump and get a photo. Here's the mapper's description: "The Spanish newspaper La Voz de Galicia invites readers to send in photos and descriptions of illegal garbage dumps. Photos and descriptions are plotted on an interactive map of the country. The intent seems to be embarrassing officials into cleaning it up." This page allows those of you who know Spanish to practice while giving those of us that don't the opportunity to be tolerant.
The California Coastal Project was a project where a pilot and photographer flew over the entire coastline of California taking aerial pictures every few hundred feet (except for Vandenberg Air Force Base which was off limits). They took GPS readings for each picture so you can click anywhere on the map and get the photograph for that location. Barbara Streisand unsuccessfully sued them for violating her privacy by photographing her Malibu estate. You can access details of the suit at this site if you really care.
