Digital orthophoto

Abstract

A digital orthophoto map is an orthorectified photo mosaic that is a basis for a successful mapping. A digital orthophoto map is one of the basic products of today’s photogrammetry and it represents its well-known and used product, and it was created based on the map users' wish to unite the detail and expressiveness of photogrammetric images, and the accuracy and precision of cartographic products. Digital orthophoto maps are widely used and are primarily the result of a constant lack of up-to-date geodetic maps. Digital orthophoto maps can be used for the development of cadastral maps and plans, topographic maps, as a basis for various GIS systems and other purposes. A digital orthophoto is a geometrically corrected photograph in a digital record, that is, a digital image translated from a central to an orthogonal projection. A digital orthophoto is a basis for making digital orthophoto maps. After a digital orthophoto is introduced into a state coordinate system and after the coordinate network and cartographic representations of land relief are projected on it, a digital orthophoto map is obtained. The paper presents the concept of digital orthophoto, as well as high-quality examples of the orthophoto of the city part of Banja Luka.
