Pushpin and a grant from a nonprofit, The Reinvestment Fund, have
resulted in PolicyMap, which looks very useful for us:
"PolicyMap is a new website that offers more than 4,000 points of data
about any location in the United States, including demographics, real
estate markets, crime, schools, housing affordability, employment
type, energy consumption, and public investments. It's powered by a
new Application Programming Interface (API) from commercial mapping
service PushPin.
That means that outside developers can access the same data that
PolicyMap does and integrate it dynamically into other services on the
web. Making this kind of information easily accessible could lead to
some very interesting location-aware mashups.
Standard use of PolicyMap is free, but subscribers get access to
proprietary data and projections, custom regions, more reports, and
the ability to upload your own data."
