Sand Ripple Profile Scanner estimates of the bed position in cylindrical coordinates.
---------------------------------------------------------------------------------------
This folder contains one .mat file every 15 minutes with naming convention HH:MMddmmyyy which includes two 2D matrices, xBed and zBed. 
xBed are the radial coordinates from the nadir of the Sand Ripple Profile Scanner in meters, and zBed the estimated vertical position of the bed (cylindrical coordinates) in meters distance to the SRPS's head.
Each column displays estimates from one swath, the swaths are spaced 1.8 degrees in direction. the 24th column represents shore-normal.
