Bing birdseye tech uses Pictometry. They have a few papers on their position accuracy. Perhaps conflicting papers. One shows the RMS error of 0.6ft. Another shows a 95% confidence level at 2.8ft. This is on 4 inch resolution imagery.
In any event, if your city uses the service, you possibly could get the planning department to provide accurate position data. http://www.pictometry.com/index.php?option=com_content&view=article&id=75&Itemid=84 _______________________________________________ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
