Accuracy Analysis of Photogrammetric Digital Topographic Map Production: The Case Study of Kuruca Village in Bingöl Center

Abstract

This study examines the accuracy analysis of digital maps produced through photogrammetric methods. With the advancements in geographic information systems (GIS) and remote sensing technologies, the factors influencing the accuracy of photogrammetric maps and the methods to enhance this accuracy have gained significant importance. The research investigates the impact of factors such as the quality of the equipment used, the distribution of ground control points (GCPs), environmental conditions, and the integration of modern technologies (e.g., UAVs, kinematic GPS, LiDAR) on map accuracy. Drawing on various studies in the literature, the advantages of UAV photogrammetry in challenging terrain, its cost-effectiveness, and data collection efficiency are highlighted. Additionally, the effects of focal length, the distribution of control points, and the software utilized on accuracy are comprehensively discussed. The study emphasizes the importance of steps such as reconnaissance, flight planning, and data processing in the production process of photogrammetric maps. Accuracy analysis evaluates horizontal and vertical deviations to determine the compliance of maps with standards and their capacity to meet user needs. The findings underscore that the accuracy analysis of photogrammetric methods is critical for the reliability and currency of maps. The integration of modern technologies and the development of new methodologies are highlighted as means to enhance the precision and efficiency of photogrammetric mapping processes. Accordingly, this study advocates for continued research aimed at improving the accuracy of photogrammetric maps.
