19. BUILDING OF TEXTURED MODELS OF CONSTRUCTIONS WITH IMAGING OF FACADES AND SIDEPIECES AT ORTHOPHOTOS
Information about type of a facade, sidepieces of buildings and constructions, about their height and spatial structure (niches, bows, balconies, etc.) is very useful for numerous practical applications of geoinformatics. Particularly, the information about conditions of buildings, available exits and entrances, window openings, breaches in walls, etc. is of great importance for topographic interpretation, planning operations of search and rescue services, planning the the activity of national security subdivisions. It is not always possible to get a three-dimensional, qualitative textured model of a building or construction due to technological, economic, organizational circumstances. The article describes the way of developing an oblique projection of a textured 3D model of a building, basing on aerial images, and visualize the model at an orthophoto. The work gives examples of practical implementation of the method. The developed model of a building presents exteriority, available entrances, windows, balconies on the facade of the building. Exterior outline of the building image corresponds to its real dimensions at the level of basement. The obtained image of the building on the back of an orthophoto practically gives the information, close to a 3D model of the LOD3 level of details according to CityGML (City Geography Markup Language) standard. In case of necessity, the depiction is supplied with abstracts (notations), defining the values of vertical coordinates of distinguished points of the building outline or elevations above the building basement to its construction elements.
