Sand Ripple Profile Scanner estimates of the bed position in cartesian coordinates.
---------------------------------------------------------------------------------------
This folder contains one .mat file per footprint of the SEDRIB campaign duration with naming convention HH:MMddmmyyy which includes three 2D matrices: x, y, and z. 
x and y show the x- and y- coordinates of the cartesian grid in meters onto which the bed level estimates are projected, referenced to the nadir position of the SRPS. 
z gives the the estimated vertical position of the bed (cylindrical coordinates) in meters distance to the SRPS's head.
