METHOD OF RELIEF COMPUTATION AND REPRESENTATION Russian patent published in 1998 - IPC

Abstract RU 2112923 C1

FIELD: relief computation and representation on plan with the aid of graph plotter. SUBSTANCE: interpolation of horizontal by coordinates is carried out. Coordinates of points are calculated with the use of formula , where x′,y′ are rectangular coordinates of points of horizontal; d,d′ are horizontal layings; Δx, Δy are increments of coordinates; x₁,y₁ are rectangular coordinates of start of reading. EFFECT: simplified method of computation. 3 dwg
