What is Grassroots Mapping?
A grassroots map of San Ignacio Loyola in Lima, Peru, produced in January 2010
Grassroots Mapping (see main web site) is a series of participatory mapping projects involving communities in cartographic dispute. This January, Jeffrey Warren of the Public Laboratory for Open Technology and Science and the Center for Future Civic Media worked with a series of organizations and communities to produce maps with children and adults from several communities in Lima, including the Cantagallo settlement of Shipibo on the bank of the Rimac and the Juan Pablo II community in Villa El Salvador.
Seeking to invert the traditional power structure of cartography, the grassroots mappers used helium balloons and kites to loft their own “community satellites” made with inexpensive cameras. The resulting images, which are owned by the residents, are georeferenced and stitched into maps which are 100x higher resolution that those offered by Google, at extremely low cost. In some cases these maps may be used to support residents’ claims to land title. By creating open-source tools to include everyday people in exploring and defining their own geography, Warren hopes to enable a diverse set of alternative agendas and practices, and to emphasize the fundamentally narrative and subjective aspects of mapping over its use as a medium of control.
Participate/Get started
To assemble your own balloon or kite rig, check out this page:
And be sure to join the mailing list so other mappers can offer advice. A good first step is to introduce yourself and tell us where you’d like to make a map.
Looking for a tough problem? Check out the Advanced Projects page; we’re looking to try these out as improvements over our existing tools!

Projects
A variety of projects have evolved both as a followup to the Grassroots Mapping Lima project and independently - here is a list of such projects and their participants:
- Grassroots Mapping Lima - A January 2010 project with CEDRO - supported by the Center for Future Civic Media and MIT’s Legatum Center
- Grassroots Mapping Belize - Pat Coyle of Belize Open Source Sustainable Development of is looking to apply these techniques marquez vs pacquiao to detailed mapping of a 40-acre property in northwest Belize and for reverse cell phone lookup other community fort worth web development mapping initiatives.
- Nu Vu Workshop: a 2-week intensive workshop is planned in late April as part of the NuVu Studio educational program in Cambridge, MA
- Illustrated Guide - A project to develop a simple, illustrated guide to Grassroots Mapping - Pat Coyle and Jeffrey Warren
- Curriculum Development - Various efforts composter reviews to develop a youth curriculum around the practice of Grassroots Mapping
- Department Of Play - Working group at the MIT Center for Civic Media of like-minded researchers and community practitioners working toward an open source mapping and media storytelling toolkit full pacquiao vs marquez tickets of tools & pedagogy to support youth participation in their local communities
- Grassroots Coral Mapping Sumatra - Crispen Wilson of Konservasi.org is mapping coral reefs in Sumatra at high and low tide.
