Integration of satellite data processing technologies of external providers into Roscosmos information system on example of the Satellite Center of the Far Eastern Branch of the Russian Academy of Sciences

Abstract

On an example of a service for merged SST charts computing, the problems of integrating a sophisticated technology of external provider into the Roscosmos State Information System for the Operational Delivery of Earth Remote Sensing Data (SIS OD ERS) are considered. The main goal of the SIS OD ERS is the implementation of a simple and uniform access to satellite data of both Russian and worldwide archives, as well as to high-level processing products in a required thematic area. External provider gets access to satellite data archives and computing resources of SIS OD ERS. The key issue is minimizing the cost of processing data from both Roscosmos and external providers. The Multiple Access Center for Regional Satellite Monitoring of the Environment of the Far East Branch of the Russian Academy of Sciences deploy its services to SIS OD ERS. The options for arranging the exchange of data and services between a provider and SIS OD ERS are proposed. A REST web services are made, with its support in the Python environment. As a result of the integration, daily merged SST charts are built that preserve the structure of thermal fronts for any water area and with the accuracy that corresponds the international standards. The service is distributed. Both the resources and data of Roscosmos and the Satellite Center of the Far Eastern Branch of the Russian Academy of Sciences, and the data from the foreign information systems are used.
