THE METHODOLOGY OF FORMING A DIGITAL RELIEF MODEL OF THE TERRAIN AND THE ALGORITHM OF ITS OPERATION

At present, the most significant information products created on the basis of Earth remote sensing data are becoming digital models of terrain relief. In contrast to the methodical approach based on obtaining terrain relief data using digitized topographic maps, a methodology has been proposed for creating a reference digital model that ensures high accuracy in solving the problem of coordinate referencing of control points due to differential processing of navigation information obtained by dual-frequency geodetic receivers.
