There are 3 sets of USA maps contained within this data set. 1) A map of the USA with the NAD 1983 Albers Projection from the USGS that was originally part of 'USGSstates2k' which has been archived and is no longer maintained.

This map comes from the USGS National Map which has been discontinued. 3) A WGS84 datum map of the USA which includes all State boundaries & also includes Puerto Rico and the U.S. Virgin Islands.
