Reply to "Ban on using paint on City streets?"

Bob Thurston can tell you about the time he had to pay a fine when he was caught painting timing points on a course in a national park in D.C. More reason to use GPS coordinates and no paint to designate points on certain courses. Of course, GPS won't work where there are nearby tall buildings, nearby hills or embankments, or overhead canopy that can all block the satellite signals.

I have noticed that it is often possible, using your recorded descriptions of points with respect to fixed objects, to locate these exact points on Google Earth. The GPS coordinates for these points as shown on Google Earth are at least as accurate as those captured on the ground,  likely more accurate by small increments. Where there is a clear sky view, these points can then be located during course layout. This is helpful not only where we aren't allowed to place paint marks, but in new development areas or where the "fixed objects" come to be less fixed than we may have supposed during the measurement.
