jaue2023075: Verification of Digital Topographic Maps Accuracy in Urban Area using on Unmanned Aerial Vehicle

Abstract

A digital topographic map is a digital geographic information map that expresses various artificial features and natural terrain, such as roads, railroads, buildings, and rivers, in diagrams and three-dimensional location coordinates on a computer. It consists of transportation, water systems and oceans, buildings and facilities, culture and facilities, vegetation, topography, boundaries, cycles, etc., and is user-centered, so it can be used for necessary thematic maps and geographic information systems. In this study, the accuracy analysis and utilization potential were studied by using the geographic information system for the construction of spatial information through aerial photography based on an unmanned aerial vehicle and a digital topographic map. A total of 436 aerial photos were used to construct spatial information through automatic route flight. The accuracy of orthoimages and digital topographic maps generated using the geographic information system were compared and analyzed. Based on the results of this study in the future, it is expected that the scope of use of unmanned aerial vehicles will be expanded when making and updating digital topographic maps.
