GPS

GPS information was collected for each target of interest at the Avon site by a dedicated team. This team carried a Trimble GeoXT GPS receiver and a camera with a fish eye lens to collect the locations of each measurement taken during the collect as well as context imagery in 6 directions: North, South, East, West, Up, and Down. The data, once post-processed, has an accuracy of less than 1 meter.
