Preparing a common raster coverage for a territory based on hierarchical compressed presentation of orthoimages

Technology for the quick viewing of georeferenced images has been developed. Principles of the organization and structure of hierarchical HGI format, which is intended to store compressed images with controlled maximal error, are presented. Additionally, a basic method of HGI format compression is described. The advantages of using the HGI format for covering a territory with orthoimages are described. Mikhail Valer’evich Gashnikov.
