Washingtonpost.com is running a great map comparing agricultural funding levels in counties across the U.S. (Via Derek). In each county the map lists the top recipients in 2005 as well as the amount they received. That means you can find all sorts of outrageous gems like Dublin Farms in Corcoran, CA, which got paid $1,828,994 by the federal government last year.
The Post map is not built on one of the big mapping APIs. I imagine that’s because the APIs from Google, Yahoo! and MSN are designed for mapping points, not areas. It is possible to use the APIs to map areas (here’s one example), but for most it’s not practical.
Since the GYM troika is developing their APIs with a singular focus on local advertising, and area mapping doesn't seem useful for local businesses, I doubt we’ll we see area mapping added to any of the APIs any time soon.
Of course, it would be great if I was wrong. As much as I like the Post map, it seems a little clunky. I want to zoom in and see exactly what this Dublin Farms outfit is doing with all its cash …
