    Re: How accurate is pinned lat & long on Google Earth?

    Here is some corrected information. On the Federal level,  the National Geodetic Survey @www.ngs.noaa.gov   is now responsible for the former USCGS  (US Coast and Geodetic Survey). I used an incorrect name/title . For the Sate of Massachusetts ( we are considered a Commonwealth by insiders) , but we still rate as a State on our flag....go figure.... the Mass Department of Transportation has apparently taken over “Survey Controls”.  My former bookmark did not function so I found my way to some info on survey controls via  “  MADOT Survey Controls “. I’ve never used this site so good luck! The USCGS site can give you BMS and reams of information about each. I recollect if you key in a Town (or maybe county) a list or map pops-up. Again, good luck.  If I have time tonight I ‘ll check out these sites.

    Here in Massachusetts we have a State Grid. You can go on line and find a “library” of Bench Marks . All BMs are defined via the  grid in a coordinate system and latitude and longitude
    Bruce, I am having difficulty in finding this online.  Could you point me to the proper url?
