METHOD FOR UPDATING ALTITUDE-GRAVIMETRIC PARAMETERS IN THE LOCAL AREA OF MAP INFORMATION Russian patent published in 2021 - IPC G09B29/12 

FIELD: geodesy.

SUBSTANCE: invention relates to the field of geodesy, and in particular to methods for refining low-precision models of the earth's surface relief, can be used to create and update digital maps of the area using topographic tablets, topographic maps, photographic maps of the area, special maps, graphic documents and others as a source material similar materials, gravimetric maps and other geophysical materials.

EFFECT: updating low-precision models of the earth's surface relief by clarifying the altitude-gravimetric parameters at arbitrary points of the local area of ​​cartographic information, in which high-precision measurements of height, acceleration of gravity and anomalies of acceleration of gravity, deviation of the plumb line, from points with altitude-gravimetric parameters, which has additional high-precision geodetic information about the height, the acceleration of gravity, the deviation of the plumb line.
