ALS-data: Airborne lidar data obtained from RWS, The Netherlands (RWS (Rijkswaterstaat, Ministry of Public Works), data obtainable via download.rijkswaterstaat.nl (Square 24HZ1, 30EN2 and 30FN1))
-ALS_Points_YYYY.xyz: pointclouds obtained from RWS in year YYYY. Data before 2012 has been obtained as geotiff files and been converted to pointclouds. X-Y-Z coordinates are in RD-NAP 
(Bruijne, A. de, Buren,J. van, Ksters, A. & Marel, H. van der, Geodetic reference frames in the Netherlands; Definition and specification of ETRS89, RD and NAP, and their mutual relationships, Netherlands Geodetic Commission 43, Delft, 132, (2005) , ISBN 90 6132291 X.)
and can be converted to local PLS coordinates with the provided global transformation matrixes. Add the height of the laserscanner (5.5795000e+01 m) to get the height in RD-NAP in PLS coordinates

Dune-Beach_pavilion-data: Dune and beach pavilion propeties. Coordintes in either X-Y or Y coordinates of the PLS data. To be used in conjuction with data in PLS_TLS-data map.
-Noordwijk_Duneheel.xy : X-Y Location of the duneheel in local PLS coordinates (m).
-Noordwijk_Dunetoe.xy  : X-Y Location of the dunetoe in local PLS coordinates (m).
-Noordwijk_Dunetop.xy  : X-Y Location of the dunetop in local PLS coordinates (m).
-Noordwijk_locations_beach pavilions.y : Y location of the beachpavilions in local PLS coordinates (m). The location indicate the southern edge of the beach pavilions. No X location is provided, but in general beach pavilions are located about 10 meters west of the dunetoe.
-
Global transformation matrixes: Global transformation matrixes from local PLS coordinates to global RD-NAP coordinates. Data consist of a 4*4 transformation matrix. Inverse transformations can be obtained by inversing the matrix.
-Global_transformation_matrix_Noordwijk_after_2dec2020.dat : transformation matrix first period.
-Global_transformation_matrix_Noordwijk_before_2dec2020.dat: transformation matrix second period.

PLS_TLS-data
-YYMMDD_hhmmss.xyz: Grid (provided as X-Y-Z file) of the beach-dune system in local PLS coordinates (m) and RD-NAP heights (m). YY,MM,DD indicate the year,month and day of the measurement while the time, indicated with hh,mm,ss as hour, minute and seconds, indicate the time of the PLS measurement nearest to the TLS surveys. PLS and TLS measurements per time epoch are combined in the grid.
PLS_TLS-data can be converted to global coordinates by subtracting the height of the laserscanner (5.5795000e+01 meter) and using the global transformation matrices to convert to RD-NAP coordinates.
