Equal area projections

Dear Colleagues

One of the central ideas of Community Analytics (CA) is that it is the "place" that is a core element of life and the associated metrics. In turn this means that the metrics of area are central ... and in turn how area is mapped.

For a small area, it does not matter what projection is used. It does not make much difference within the community itself ... but it matters a lot in the depiction of the world as a whole. I believe that the most widely used projection is the Mercator Projection which converts a globe into a cylindrical surface ... but I would argue that the projection developed by cartographer Dr. Arno Peters in 1974 giving more accurate area depiction would be best to use in conjunction with Community Analytics (CA). http://www.petersmap.com/

Any thoughts?
