Notes This image product consists of AxelGlobe Cells, 5 km x 5 km per tile. This product is intended for applications that require accurate location information and map projection images. The image product is processed with sensor correction, geometric correction, and map projection. In addition to extracting the Ground Control Points (GCP) from the reference base map using proprietary technology, geographic correction is applied by combining conventional methods for areas where automatic GCP extraction is difficult. The location accuracy of the image product depends on the GCP used and may vary from region to region.
