Development of a United Geographically-Distributed Information System as the basis of Russia ground infrastructure for Earth remote sensing from space

   United Geographycally-Distributed Information System for Earth Remote
   Sounding (UGDIS ERS) is a complex of ERS database information, information
   technologies and technical means for its registration and processing and
   installed at geographycally-distributed centers and sites of ERS data
   registration and processing of the Russian Federation executive authority
   federal bodies, Russian Federation subject executive authorities and of
   other organisations involved in ERS data registration and processing.

   UGDS ERS is functionally subdevided into the following subsystems:

   - subsystem for planning and controlling of ERS data acquisition
   processes;

   - subsystem for ERS data reception, registration and processing;

   - subsystem for ERS data storage and distribution;

   - subsystem for data exchange.

   One of the most important elements of UGDIS ERS infrastructure is a united
   geodata bank. The united data bank was created and is being developed as a
   distributed information system which unites the data of federal,
   departmental, regional and other geodata banks.

   The united geodata bank is to solve the following tasks:

   record, acquisition, systematization, long-term and operative storage of
   geodata in data bases and archives;

   formation of a United geodata catalogue;

   automatic formation and processing of requests to get geodata archives,
   requests to carry out survey and RES data processing;

   formation, storage and update of raster continuous cover of the Earth
   surface on the basis of RES data;

   operative access for the users to the data resources of the bank according
   to access rights.

   During the development of the model for metadata description in the United
   catalogue as well as to solve the tasks of unification of metadata
   acquisition and presentation, ?Metadata profile of the United geodata bank
   on the basis of ISO-19115, ISO-19115-2 and ISO-19139 standards was
   developed in the Research Institute of Precision Instruments.

   The United geodata bank includes central and regional banks. Proposals to
   organize cooperation of UGDIS ERS and RAS information systems have been
   formulated. Cooperation of UGDIS ERS and IKI RAS geoinformation system is
   already developing on the basis of service-oriented technologies.
