I am looking for projection information for your Mexican Municipios data. I need to reproject the data and I need to know what the original projection was for the coverage.

The projection of the data you are interested in is as follows:

Projection: LAMBERT (Lambert conformal conic)
Units: METERS
Spheroid: CLARKE1866

Parameters:
1st standard parallel 17 30 0.000
2nd standard parallel 29 30 0.000
central meridian -102 0 0.00
latitude of projection’s origin 0 0 0.000
false easting (meters) 0.00000
false northing (meters) 0.00000

There is also an updated version of the Municipios coverage (with fewer attributes) available in the geographic projection at: http://sedac.ciesin.columbia.edu/data/set/geo-mex-mexico-states-municipalities-islands-gis
