FIELD: geodesy.
SUBSTANCE: method can be used for cadastre metering of terrain with complicated shape. Massifs of digital models of terrain are achieved by aerospace means providing high spatial resolution. Array of digital models of terrain is divided to fragments to get 2x2 adjacent pixels window. Window is divided to triangles by diagonal. Shape is presented in form of array of inscribed triangles which have vertexes to be adjacent pixels of digital model of terrain. Area of any triangle is calculated by means of Pythagorean Theorem and Geron formula. Areas of all the windows are summed.
EFFECT: improved precision; improved truth of data.
