Note: the RTK GPS all-in-one antenna records UTC time, local time can be found by adding 1 hour. 
The pole antenna height (2.00 m) and wheel antenna height (1.485 m) are already subtracted from the datapoints.

Within the folder of the survey days are the following files:

	YYYYMMDD_INSTRUMENTS: The coordinates in RDNAP and/or orientation of the deployed instruments and poles to which they were attached. 
	
	SXX_YYYY_YY_TOP/SEN/BED/ORI_ZZ
	
	XX: station number
	YYYY_YY: type and number of instrument
	TOP: the GPS recorded the top of the instrument
	SEN: the GPS recorded at the height of the sensor
	BED: the GPS recorded at the height of the bed near the instrument
	ORI: the GPS recorded the orientation of the positive x-direction (Nortek ADV) or positive y-direction (JFE). The first points are recorded near the instrument, the second set is recorded at a reasonable distance from the instrument in the desired orientation. 
	ZZ: number of point recorded (in case several points for an instrument were recorded for increased accuracy)
	
	YYYYMMDD_TRANSECTS: The central transect for each dune. This is also the transect on which the instruments were placed.
	
	YYYYMMDD_WALK: Walking survey
	
The header of each folder is:
description, date, time, x, y, z, 2d_error, 3d_error
