USGS code info


Recommended Posts

Jerry Penry, a professional who frequently comes up with topics of interest, has published an article about USGS bench marks and the various datums they were on. He is building a list of codes stamped on USGS disks. He would welcome any additional codes or information relating to them.


See his post at the professional surveyors forum for the links.
