UdSIMsniff

From The Urban Dead Wiki

udSIMsniff is a Greasemonkey script deigned to work hand-in-hand with the website sim.urbandead.info, allowing "one click" uploading of Scent Death map information to that website. The website uses a database to create a map that combines Scent Death information collected around the city, and provides any visualization tools for this info, such as annotated maps and historical archive views. The same basic map image (found here) is used by SIM and Omnimap.
