Some notes.
Reading geography and maps as sites of power, deconstructing assumptions and political implications of maps. See http://en.wikipedia.org/wiki/Critical_cartography, Siam Mapped, Spaces of Capital
Using and creating maps to challenge power and facilitate social change, often characterized by an oppositional, anti-authoritarian politics. See An Atlas of Radical Cartography, NYC Guide to War Profiteers, Million Dollar Blocks.
Producing maps that challenge the dominant, mainstream narrative of a site or history, often from an explicitly political or activist perspective or from the point of view of historically marginalized communities. See DisOrientation Guide, CrashStat, A Threat to Peace, Notes for a People’s Atlas of Chicago.
Maps produced collaboratively by a geographically local community, often used to promote a social agenda. See Green Map Systems, Asset Mapping, Aboriginal Mapping Network.
