The New York City Open Accessible Space Information System Cooperative (OASIS) is an online, interactive mapping and data analysis application that gives an incredibly detailed view of New York City's open spaces and how they are used. The map enables overlays of information like: transit; parks, playgrounds and open space; zoning and landmarks; current and historical land use; social services; demographics; and environmental characteristics.(via The Ministry of Type, who like OASIS mainly for its pretty map possibilities.)

The ThreeRing Web Mapping project adds a dot to a blank canvas showing your geographic location (or that of your ISP, as best it can guess based on your IP address). They've also got a code snippet to put on your own site that automagically adds your visitors to the map. The US is already clearly defined, Europe is getting there, and Oceania is coming into view. (They've also got one of them Tag-Board thingies, which is painful to read for any length of time.)
