# DGPS measurements on Balgzand intertidal area, on 20 May 2012.
# These measurements were performed to verify the accuracy of the bathymetric maps,
# and to determine the height at which the pressure loggers to measure tidal
# height were deployed
#
# grid: grid identifier
# patch_id: patch identifier, corresponding to the grid patches used in the benthos sampling. In the field, it was attempted to position the DGPS at the position of this grid point, to measure the bathymetry at that location.
# RDX: x coordinate in Rijksdriehoekcoordinates (Dutch national grid), as measured with DGPS
# RDY: y coordinate in Rijksdriehoekcoordinates (Dutch national grid), as measured with DGPS
# NAP: vertical coordinate in NAP (Dutch national grid, mean sea level), as measured with DGPS (in metres).
