I usually us US National Atlas Equal Area - Meters (SRID 2163) Though maybe I should try the below and see how my numbers match up.

Hey All, I'm wondering if there's an official or standard projection that covers the continental US? When I first joined the list, Paul kindly provided this: INSERT INTO SPATIAL_REF_SYS VALUES (1000000,'ME',1000000,'','+proj=aea +lat_0=23 +lon_0=-96 +lat_1=29.5 +lat_2=45.5 +datum=NAD83 +ellps=GRS80'); It seems to work accurately enough, I'm just curious if there's a standard definition like those in spatial_ref_sys.sql.
