Seems a lot of attention has being paid to information visualisation using maps recently, such as projects like GeoURL and Zipdecode. Overlaying geographic data onto a map is interesting, but I also like it when this geographic data is combined with local photography to produce a map of an area that can be viewed at different scales through photos of each section.
Seamless City - creates a small scale photo map, stitched together house by house
NYC in pictures - is a block by block photo representation of New York’s streets
Similarly, RAW uses photos to create a timeline based map, and Cinema Redux uses photos to create a map of a movie. The notion of a map as a plan of physical space is expanded upon. In a way, I suppose all data visualisation is mapamaking.
Update: More photo mapping of a city, London this time, in Street Sensation.
