Republic geodetic authority published on national geoportal “GeoSrbija” true-orthophoto for urban area of Novi Sad and area “Belgrade Waterfront”.
On the 25th of July 2014, true-orthophoto of 10 cm resolution produced for the urban area of Novi Sad with total area 108 km2, as well as true-orthophoto of 10 cm resolution produced for the area of “Belgrade Waterfront” with total area of 5 km2 , have been published on national geoportal “GeoSrbija” at the Orthophoto category.
True-orthophoto of the urban area of Novi Sad and area of “Belgrade Waterfront” are produced on the basis of the aerial image acquisition realized in 2011 within framework of IGIS project. Aerial image acquisition has been performed by digital, multispectral, photogrammetric camera UltraCamXp of 6 mm resolution, and with the side and long lap between images of 80%. Geo-referencing parameters of produced true-orthophoto are defined by the parameters of SRB_ETRS89/UTM reference system at the projection plane, while the mean square error of positional coordinates is ± 20 cm.
The main advantage of true-orthophoto, if compared to a classic digital orthophoto, is that the effects of objects image radial displacements are removed, meaning on true-orthophoto objects are converted to the orthogonal projection which is why its use in the process of spatial and urban planning and maintenance of a spatial registers is extremely important bearing in mind the quantity and quality of spatial information provided.
