The Distributed Infrastructure for Operative Satellite Monitoring for the Siberian Branch of the Russian Academy of Sciences

Reporter: Shokin Y.

We describe the distributed system for storage, processing and distribution of satellite remote sensing data and results of its analytical processing. This system is being developed to support operative monitoring tasks and studies of the environment. The data and products are available through the infrastructure of the Collective Cooperative Access Center for Spatial Data Processing and Remote Sensing of the Siberian Branch of the Russian Academy of Sciences.

The architecture of the system is based on a solid foundation of unified data models that facilitate the integration of geospatial data from different sources and its provisioning in different formats depending on the requirements of specific research projects.

In the past 5 years the system passed through several stages of development. During this period the data models and application protocols proceeded through the stages of parallel iterative refinement where the capacity of the infrastructure being developed was continuously validated with test applications. Several technical issues were resolved in the process both in the areas of mapping algorithms onto contemporary distributed architectures and in the areas of environmental monitoring.

When the architectural design of the system has stabilized an effort was applied to optimize the performance of its subsystems such as the data processing framework based on the principles of stream processing. The system is fully automated and is currently operating in production mode.

The study was supported by RBRF grant 12-07-00545-а and by project #131 of the SB RAS program of the integrated basic research.
