ПОСТРОЕНИЕ ЦИФРОВЫХ МОДЕЛЕЙ РЕЛЬЕФА ПРИ ПОМОЩИ КУБИЧЕСКИХ ПАРАБОЛ

Abstract

The method of digital elevation matrixes constructing is put forward. The method is based on a mathematic model using algebraic polynomial of power 3. The distance from current grid node to contour line is measured along the heights gradient. The analysis of comparison of different DEM-compiling methods accuracy is done and some possible applications of the method suggested are shown.
