摘要

FIELD: measuring equipment.;SUBSTANCE: at a controlled area a field-compilation survey is created by X, Y, Z coordinates of satellite binding of identification signs. An aerial photography of a given territory is performed by unmanned flying vehicle with reference to system of coordinates of the field-compilation survey. The results of the aerial photography are transmitted to the PC. By means of a computer program, processing of the aerial photography materials is carried out and a cloud of points is obtained in the form of a digital metric three-dimensional point model of the given territory. Then a digital model of the surface in the form of a triangulation model is created by means of a computer program, a matrix of heights and an orthophotoplan for subsequent update of the address plan are created, the orthophotoplan is decrypted. Then a digital address plan of the given territory is created or updated by a computer program, an interface subsystem for preparation and constant updating of the geospatial data is created and the surface digital model is transmitted thereto in the form of a triangulation model, the matrix of height, the orthophotoplan and an address plan of the given territory. In the automated mode, the classification of the surface triangulation model of the given territory is performed for detecting objects of building and infrastructure of the given territory by selecting triangles belonging to these objects. By means of the computer program, according to classification results, the triangles of the digital triangulation model of the given territory surface belonging to these objects are assigned with the corresponding attribute data. Then in the same interface subsystem for preparation and constant updating of the geospatial data a digital reference design model of the given territory is modeled consisting of said surface digital model in the form of a triangulation model of the given territory. For this purpose, maximum permissible values of spatial coordinates of ground objects are integrated into the specified digital model using thereof design values. In this interface subsystem for preparation and constant updating of the geospatial data, information is automatically entered in real-time mode in the form of attribute hydrological data on water level in controlled area in system of coordinates of the filed-compilation survey. By using the computer program, two-dimensional models are constructed based on the orthophotoplan and the three-dimensional models of flooding zones with the use of the attribute data on the water level at the controlled area in the system of coordinates of the field-compilation survey. In the same interface subsystem for preparation and constant updating of the geospatial data by combining said digital triangulation model of the given surface territory and the results of aerial photography in the form of digital aerial photographs create a digital, textured three-dimensional model of the terrain of a given territory with the possibility for visualisation of the actual or modeled flood situation at the monitored site. In the same model, the construction of isolines is virtually performed to connect the points of the textured model in accordance with the hydrological data about the water level in the controlled area in the system of the coordinates of the field-compilation survey in real-time mode. As a result, a three-dimensional and two-dimensional model of flooding zones is obtained. The administrative subsystem is used as a server of geospatial data for performing control, processing, analysis, interpretation and storage of the obtained geospatial data and transfer thereto said digital textured three-dimensional model of the terrain and three-dimensional, and two-dimensional models of flooding zones from the interface subsystem for preparation and constant updating of the geospatial data. The interface subsystem for visualization of the geospatial data is used by providing service to users based on internet technologies. The geospatial data is used in real-time mode and together with attribute data on objects and landscape of the given territory. An interface subsystem for monitoring the operative situation is used, in which a system for calculating consequences in emergency situations from flooding of territory with the possibility of interrogation is created, visualisation and generation of reports in the form of summary tables and situational maps for planning anti-flood measures or eliminating the consequences of extreme situations in controlled area by calculating in automatic mode the difference between actual values of heights of digital three-dimensional model of the flooding zone and the corresponding values of the digital reference design model of the given territory in the system of coordinates of the field-compilation survey.;EFFECT: increased efficiency monitoring due expanded functionalities.;1 dwg
