ALGORITHMIC SUPPORT OF THE EARTH REMOTE SENSING DATA PROCESSING COMPLEX IN TERMS OF VISUALIZATION OF REFERENCE DATA

The paper discusses protocols for accessing reference data during client-server interaction, as well as an asynchronous algorithm for visualizing the received data. Protocol descriptions and recommendations for using the most appropriate protocol for visualizing the reference raster coverage during interactive work are presented. There is also a scheme for indexing tiles in the form of a pyramid of scales. An algorithm for asynchronous query and visualization of reference data is considered and a scheme for processing reference data requests is presented. The work also takes into account possible errors during client-server interaction and their processing.
