METHOD OF CONSTRUCTING MAP OF EXOGENOUS GEOLOGICAL PROCESSES OF AREA ALONG ROUTE OF MAIN OIL LINE Russian patent published in 2016 - IPC G01C11/00 

FIELD: laser engineering.

SUBSTANCE: invention relates to production of topographic data on the Earth surface relief according to aerial photography and laser scanning area from board of aircraft, particularly to monitoring of main oil pipeline route sections (MP) for detecting signs of exogenous geological processes (EGP) and fixation of boundaries thereof. In method of constructing map EGF area along route MN digital aerial photography and air laser scanning. That is combined with collecting and recording of navigation data for generating and recording coordinates of points of flight trajectory. Processing data of aircraft laser scanning and navigation data. Obtaining cloud laser reflections and on basis of their automatic classification with interactive correction of results of constructing digital elevation model (DEM) area. According to DEM formed in construction surface inclination angles derivatives map slopes area. Simultaneously with construction of DEM data is processed digital aerial photography. Using results of constructing digital elevation model, maps slopes and orthophotomap area is detection and formation of map EGP flowing on area along route MN.

EFFECT: technical result is high accuracy of detecting and determining EGP with reduction of labour intensity and duration of inspection.
