FIELD: data processing.
SUBSTANCE: invention relates to the creation of three-dimensional digital models. Method of obtaining, processing, mapping and interpretation of geospatial data for geodetic monitoring of the deformation state of an engineering one contains the steps of creating horizontal and vertical survey (HVS) in the local coordinate system by air defense support points in the controlled area, where HVS is carried out with the use of laser scanning technology, where the base GPS stations are deployed as HVS reference points of the air defense system, located in a certain circuit around the monitored engineering facility; at control points on the structural elements of the engineering object establish a geodesic control and measuring equipment (CME), with the help of which the field observations by geodetic methods are carried out for the planned high-altitude displacement of the structural elements of the engineering object, in addition, digital sensors are integrated into the said CME, with the help of which geospatial data are obtained on the coordinates of the engineering object's X, Y, Z elements.
EFFECT: increased reliability and accuracy of the obtained geospatial data by using laser scanning technologies in three-dimensional space.
