GEOSPATIAL TECHNOLOGIES IN THE CONCEPT OF SMART CITY: ANALYSIS AND STUDY OF EXAMPLES OF USE
The importance of geospatial modelling to support decision-making in Smart city is described. Geospatial information sources for geo-information decision support systems are being analysed. remote sensing of the Earth is a common source of geoinformation, but the speed of decision-making in this case is not high. At this very moment it is more expedient to use distributed networks of smart sensors, which also could be carried by people, as sources of geospatial information, because in this case it becomes possible to perform monitoring in real time. It is noted that sensors can also be used in building information modelling (BIM), while in conjunction with BIM it is expedient to use geoinformation systems. Geoinformation solutions based on researched sensor networks are being investigated. It is shown, that the researched geoinformation solutions can be divided into three groups: carrying out continuous control, carrying out the detection of events, and consisting of mobile network of sensors. It is noted that on the basis of the distributed network of smart geosensors and in order to process the spatio-temporal data streams in the geoinformation system of decision support in Smart city data stream management systems should be used.
