Publicly available spatial data as a source of coordinates for ground control points

Popis výsledku v původním jazyce

Nowadays, direct georeferencing methods, utilizing GNSS receivers and Inertial Measurement Units (IMUs) on aircraft carriers, are commonly employed to generate products from aerial imagery, including orthophotos and digital elevation models. However, certain scenarios necessitate the utilization of signalized ground control points, such as when higher accuracy is required, large areas need coverage, or GNSS correction data is unavailable. This paper explores leveraging publicly available data, such as orthophotos and digital elevation models, for photogrammetric projects. The methodology involves identifying identical points suitable for embedding from both publicly available data and acquired aerial photographs, retrieving X, Y coordinates from orthophotos, and Z coordinates from elevation (LiDAR) data. Evaluation using advanced geostatistical methods in urban areas and application to landscape documentation in Bohemian Switzerland National Park with diverse photogrammetric sensors demonstrate that the resulting data falls within the accuracy class, meeting standards possibly sufficient even for cadaster needs (based on the national decrees). This approach accelerates photogrammetric imaging preparation and implementation, particularly when aerial vehicles with IMUs are impractical. Moreover, it contributes to reducing the carbon footprint of aerial imaging by limiting motor vehicle movement within the area of interest.
