This paper aims to assess the geometric accuracy of large-scale digital orthophoto produced from aerial photography in the project area. Since accuracy assessment of digital orthophotos is a complicated issue some main factors and parameters that affect digital orthophoto accuracy are briefly explained and discussed throughout the study. For this aim it is investigated the accuracy of digital orthophotos produced in a project for large scale (i.e. 1/1000) digital photogrammetric map and orthophoto production in Kocaeli city. The estimated orthophoto accuracies in the project were found to be quite adequate and acceptable according to the national and international standards. The results also serve for a crucial approach for the usability and cost efficiency of digital orthophoto imagery for the production of large scale national standard maps.
