ABSTRACT:
Numerous applications of Earth observation (EO) data for Earth resource exploration both for land use management purposes and
for fundamental research goals require as much as possible independent EO data sets provided for a number of data consumers, i.e.
for collective (shared) data usage. In addition data distribution procedures should be accompanied with sophisticated information
services enabling correct interpretation and application of provided data. As a result data providers should be able to convert data
in a lot of consumer-proper formats and in some cases it should require additional data processing before data shipping. Presented
work proposes basic infrastructure for collective (shared) EO data usage that enables above mentioned integration of information
resources contained in typical Russian EO centers. Paper reveals architecture design, description of basic infrastructure elements,
and examples of real implementations.
1. INTRODUCTION
Numerous applications of Earth observation (EO) data for
Earth resource exploration both for land use management
purposes and for fundamental research goals require as much
as possible independent EO data sets provided for a number of
data consumers, i.e. for collective (shared) data usage. In
addition data distribution procedures should be accompanied
with sophisticated information services enabling correct
interpretation and application of provided data. As a result data
providers should be able to convert data in a lot of consumer-
proper formats and in some cases it should require additional
data processing before data shipping.
Main object of presented work is to design and implement
basic infrastructure of collective (shared) EO data usage that
enables integration of information resources contained in
typical Russian EO centers. The principal approach in
infrastructure development is based on data exchanges via
wide use of unified integrated data sets (UIDS) which describe
explored natural physical object or geographic zone, including
observation data, products of data processing, metadata,
browse images, and guides (glossaries, directories,
descriptions, user manuals).
Basic element of developed infrastructure that should manage
UIDS is Information Resource Integration Block (IRIB). IRIB
should solve the following fundamental tasks in supporting
distributed system functionality:
1) for each distributed system node that stores EO data IRIB
should support all stack of services necessary to manage UIDS,

i.e. data search and localization, data conversion, UIDS
assembling, and data shipment,
2) IRIB should enable simultaneous access to several
distributed system nodes which contain information describing
the single natural physical object, so IRIB provides complex,
i.e. multi-sources, UIDS,
3) IRIB should posses ability to transform data set to UIDS
allows to build up unified interfaces of shared (collective)
access for visualization of EO information resources as well for
their on-line processing and analysis.
To integrate resources of distributed system along with IRIB
the unified interface for collective (shared) usage (UICU)
should be developed. UICU should enable the simultaneous
receiving EO data and products as well their descriptive
information metadata, browses, and guides. In addition, EO
UICU allows to perform on-line reconfiguration of finalizing
data processing by user request via special interface.
Paper describes architecture design supporting required service
stack, shows details of basic infrastructure element (IRIB and
UICU) functionality, and reveals results of real implementation
of proposed approach in IKI GEOSMIS technology developed
by Space Research Institute team.
