Trying to convert an old .e00 gis file collected from the us census bureau to arcView. Then from ArcView into a shape format that Google maps can plot. There is a ton of discovery involved specifically with the types of map projections the census bureau uses. There might need to be some normalization, but until I plot my data, I won’t know (their data is extremely undocumented). Anywho…. I’ll be updating my progress.

Update: Gave up on the arcView format because of it’s proprietary nature. Looks like arcview is pretty expensive, so I’m using the ascii formated data set which seems to be a space and line delimited list of coordinates (found here: http://www.census.gov/geo/www/cob/co2000.html). Here’s the general format:
2 -0.737111200944987E+02 0.447554053271605E+02
-0.740250260000000E+02 0.449800360000000E+02
-0.740274011055598E+02 0.449957651692313E+02
-0.740274011055598E+02 0.449957651692313E+02
END
Looks like the first line is the center point of the shape, where each proceeding line until the “END” represents each point in the polygon.
