Analysis of aerial photography data using GIS

The article considers an approach to the construction of complex distributed, implemented on the platforms of fog and edge computing, cyber-physical systems with a high level of architectural dynamics. The article discusses the issues of processing and analyzing images obtained from unmanned aerial vehicles. Orthophotomap and digital terrain model constructing model has been developed and implemented using data received from «Geoscan» LLC. As a result, 7 raster TIFF format orthophoto maps were created with accuracy of up to 0.025 meters. A geodatabase was built in the geographic information system into which the resulting orthophotomaps were imported. Based on the orthophotomaps, a raster mosaic was created, background and the color balance were adjusted. The resulting terrain image was analyzed, a slopes map, surface aspect, hillshade and a realistic image of the terrain were created. Aerial photography data analyzing algorithm, can be applied for processing any images obtained from unmanned aerial vehicles. The results obtained can be used for survey work, land management, architectural and construction design, environmental monitoring, and agriculture.
