Data

You have to prepare an ascii file with extension .xyz containing the geograph­ical coordinates and level of the dune foot. The file format is three space sep­arated floats (real numbers) for the x- and y-coordinate and z-level on separate lines for each of the points. You must also select the map projection in which you have specified the geographical coordinates.

NOTE: (.xyz) input files must be provided in metric unit [m]
