资源简介：
The digital virtually seamless orthophoto of the Czech Republic in 8-bit colour. The pixel of the Orthophoto CR raster image represents 0.125 m of terrain in the mean terrain plane. The positional accuracy of the Orthophoto CR, expressed as the total root mean square error, has shown long-term improvement. Since 2021, the total root mean square error of the Orthophoto CR has stabilised in the range of approximately 0.18–0.20 m (see the Technical Report on the Orthophoto CR). The Orthophoto CR is distributed in the JPEG raster format in distribution units covering 2.5 × 2 km of terrain in the SM 5 map sheet layout. The data files are provided in JPEG format accompanied by world files (JGW) for the S-JTSK, ETRS89-TM33N, and ETRS89-TM34N coordinate systems. Files are provided in compressed format (ZIP).
