Summary. For treatment of results of radio-location of surface it is suggested 
to use the mathematical model of surface as formulas of spline- interstripation,
that uses for renewal to the surface of her image on the system of intersecting 
(in general speaking) stripes. If stripes degenerate in a line, then 
interstripation ї passes to interlineation. Interstripation also gives 
possibility to the transition from задання of mathematical model of surface 
with the use of інтерстріпації functions to other widely-used mathematical 
models of surfaces(for example, with the use of the system DEM)
