  1. Is it possible to either A) note on a site's data page whether the coordinates are are are not WAAS corrected or ;) notify the owner of the site with more accurate coordinates. I'm getting frustrated finding cahces that are 50 feet away from their coordinates!


    What do you think?

  2. Even with WAAS, sport grade GPS doesn't come close to professional grade GPS. I have a unit that is +- 10" that cost over $8,000 ... the units that get centimeter accuracy required for land surveying cost over $20,000.


    If you are interested in the process that surveyors go through to recover benchmarks, check this on-line magazine:



    It very often has articles on rectifying older surveys with new technology.
