APPLICATION OF TERRAIN STEREOMODELS FOR DECODING AND DETERMINING THE COORDINATES OF CHARACTERISTIC POINTS FOR REAL ESTATE OBJECTS IN COMPLEX CADASTRAL WORKS
The article considers applied aspects of using a photogrammetric method of determining the coordinates of cadastral registration objects by way of creating terrain stereomodels. The purpose of the study is to evaluate the advantages of using stereo models based on the proposed technological solutions that expand the capabilities of the photogrammetric method in complex cadastral works. The obtained results of the study justify the expediency for expanding the technological capabilities of the photogrammetric method as for collecting and processing geospatial data in the field of cadastral activity, methodological recommendations to organize production activities while the implementation of complex cadastral works and improving the quality of spatial data included to the state real estate cadastre. The solutions suggested are justified to reduce the future possible errors while decoding, due to the additional use of angles with reliable unambiguous interpretation of characteristic points. In order to improve the technology of complex cadastral works, the study determines the values of coordinates discrepancy obtained by the photogrammetric method and control measurements, as well as the types of "fixing" characteristic points calculating the most probable mean square errors in coordinates. The research also provides recommendations on the value for overlaps of images and accuracy criteria to prepare initial oriented images in complex cadastral works.
