Ulteri considerazioni sulla correzione topografica nei rilievi gravimelrici geominerari



In t h e present paper we are dealing with residual error
occurring when considering surfaces of cylindrical compartment in gravimetric
topographic correction, horizontal.
I t is shown how residual error variations in a compartment depend
on the average level, average slope and slope o r i e n t a t i o n of topographic
surface in t h e compartment.
The residual error of a zone or a n ensemble of zones may be positive
or negative according to s t a t i s t i c a l distribution of slope orientations. As
a n example, the results of a gravimetric survey are related.
Rapid methods to value t h e residual error and to eliminate it in some
cases are suggested.
