ORTHOPHOTO

Digital orthophoto (DOP) is a georeferenced digital image of a part of the Earth's surface with determined dimensions, that has characteristics of orthogonal projection, obtained through the process of ortho-rectification of digital aerial photogrammetric imagery, digital satellite imagery or imagery obtained through the other methods of remote sensing.
Digital orthophoto is a digital topographic base that contains all the information registered on the image used for its production (significantly more information against the classical topographic maps), but also all measurement properties of topographic maps with the appropriate detail level.

The technology of producing orthophoto mosaic i.e. digital orthophoto represents one of the most cost-effective and efficient methods of obtaining the up-to-date topographic base maps. Digital orthophoto is the product of survey using the remote sensing method, which provides rapid and mass acquisition of geospatial data and provides presentation of topography of the surveyed area. By selecting the appropriate ground sampling distance, the level of detail and accuracy required for particular purposes is assured.

The GIS oriented environment facilitates combining orthophoto with other types of spatial data, and for that reason it is appropriate for use in spatial and statistical analysis, while representing a simple and practical solution for overcoming the lack of up-to-date base maps and rapid registration of spatial data.

Digital orthophoto is a product with the application that facilitates the adequate implementation of numerous development projects on national, regional and local levels in the field of planning and development, agriculture, environment protection, processes of privatization, establishing information systems, disaster management, for the purposes of defense and many others, while representing a foundation for every type of work for which the up-to-date spatial data are of exceptional importance.

The Republic Geodetic Authority has at its disposal the digital orthophoto data obtained from aerial photogrammetric acquisition for the territory of the Republic of Serbia (except AP KiM) from the epochs of 2007-2010 and 2011-2013, as well as for the certain location produced from aerial photogrammetric acquisitions performed in 2001, 2003 and 2007.
The latest digital orthophoto data have been produced from the high resolution satellite imagery from epochs of 2015-2016 and 2020-2021 and are available at the National Spatial Data Infrastructure portal GeoSrbija.

Issuing of the digital orthophoto data is regulated by the Law on republic administrative fees and the license agreement between the Republic Geodetic Authority and the satellite imagery distributor.
