FIELD: physics.
SUBSTANCE: invention relates to methods of correcting an elevation map. Technical result is achieved by performing the following steps of the method: receiving a satellite image with one or more roads; fixed GPS system data corresponding to one or more roads are received; determining a pixel on the satellite image corresponding to one or more roads; determining whether the pixel location corresponds to the GPS system data; if it is determined that the pixel location does not correspond to the GPS system data, a set of digital elevation model (DEM) pixels surrounding said pixel is determined; height of each pixel from the set of DEM pixels is corrected so that the location of the pixel on the satellite image corresponds to one or more roads.
EFFECT: reduced error when constructing a digital elevation map.
