The shared Python tool appears to generate a *.grid file which the SARndbox accepts, yet what is resolved is the software signaling the construction of a level sand surface.
The currently modified *.asc elevation file has approx. min./max. of -107/-75 respectively in an attempt to reflect the box configuration range of -114 to -105.
The original elevations were 116 to 165 (MASL).
Should the *.asc inputs elevations be associated with the sandbox elevation plane distance from the kinect, or is perhaps some other normalization necessary?
