[QUOTE="H3Alpha, post: 73210, member: 12955"] Can't agree with what, the typical accuracy? Take a look at any handheld GPS unit, or any GPS app on your phone that shows it's accuracy. For anything under 15' accuracy, you will need either perfect conditions (maximum # of satellites, evenly spread out across the sky, no trees/buildings, etc), or high dollar commercial surveying GPS equipment. Here's an explanation: "The United States government currently claims 4 meter RMS (7.8 meter 95% Confidence Interval) horizontal accuracy for civilian (SPS) GPS. Vertical accuracy is worse. Mind you, that's the minimum. Some devices/locations reliably (95% of the time or better) can get 3 meter accuracy. For more general GPS accuracy information, head to GPS.gov's [URL='http://www.gps.gov/systems/gps/performance/accuracy/']website[/URL]. That website also includes data and information on WAAS-enabled systems and accuracy levels depending on location. It's a great resource. Basically, you can't get 2 meter accuracy reliably without some form of correction."
