Berkeley sound elevation data from DGPS

The dataset is a list of points (id, lat, long, height) taken at 6 sites in Berkeley sound (Diamond Cove, Magellan Cove, near Green Patch, Long Island, Strike off point and Kidney Island) from the water mark up to about 200 metres inland. The points were taken using a differential GPS device (DGPS) in order to be able to map the profile of the coastline and provide accurate height of the terrain at fixed locations.

Lineage	A DGPS device, Leica CS25 GNSS plus, was used to capture points from the water mark level to approximately 200 metres inland. Overall all transects have been taken perpendicular to the coast following the steepness gradient, nevertheless some of them were taken following an oblique line. The results from the DGPS should prove very useful to enhance the quality of the stereoscopic image that will be used to extract and elevation model for the surveyed areas. The DGPS uses a fixed, ground-based reference station, which for the Falkland Islands is located near SURE's earth station, to broadcast the difference between the positions indicated by the GPS satellite systems and the known fixed position. A reference station calculates differential corrections for its own location and time. Generally the accuracy of DGPS decreases with distance from the reference station. Nevertheless the distance range from the surveyed sites and the Stanley ground-based reference station was acceptable and should not decrease the accuracy of the DGPS.
