An Application of High-Resolution Mobile Mapping in Smart Cities: Gaziosmanpasa Case Study
Keywords: Mobile Mapping, LiDAR, Smart City, 3D Point Cloud, Panorama
Abstract. In this study; with the mobile mapping of Gaziosmanpaşa district, measurements such as metric measurement, silhouette analysis, updating numbering data on surfaces, signage inventory for taxation process, digitization of traffic lights for advertising services and traffic control are easily made with a panoramic image with a resolution of 100 Megapixel (Mp) and a laser point cloud with an accuracy of ±3 cm. Since the surface calculation of the digitisations to be made for inventory extraction is important, the accuracy analysis was performed by comparing the point cloud data here with the ground measurement. In this analysis, z values were evaluated. Deviations that may occur in high-rise buildings have been observed. Since the measurements made on the building surfaces are especially important for smart city applications, the margin of error of the measurements should be taken into consideration. During the measurement, the error contained in the point cloud density taken due to traffic was evaluated with coordinate values taken at 16 points.
