Paper maps are becoming obsolete.  A talk about the lack of accuracy in our GPS.  You will want to watch this video talk: Todd Humphreys: How to fool a GPS

This is why we ALL  NEED to participate in Survey Earth in a Day 2.0.  Only the members of this network have the capability of changing the state of GPS accuracy.

Less than 18 days until we measure the planet as a community during the course of a single day.  Get involved!
