Well you'll need to translate those into addresses. That should be easy with Google or Bing.
We have the addresses, need census tract and block.
For small address batches you can use the Census Geocoder. The documentation is at
http://www.census.gov/geo/maps-data/data/geocoder.html
Basically you upload a CSV file addresses and you'll get back FIPS codes for state, county, census tract and census block for each address. Concatenate the FIPS state+county+censustract code (not the census block).
This turns out to be the least hassle, thanks to all in the group who replied. Note that although the Census website says that it will handle a CSV file of up to 1000 addresses, in reality it pukes on anything greater than about 100 at a time. -- -- Jay Hennigan - CCIE #7880 - Network Engineering - jay@impulse.net Impulse Internet Service - http://www.impulse.net/ Your local telephone and internet company - 805 884-6323 - WB6RDV
