DREAM

DREAM Project

Executive Summary

This technology development project will address the architecture and Payload Data Ground Segment  interfaces needed to streamline the feasibility analysis, planning, ordering and access to ESA and third party missions Earth Observation (EO) products for two European institutions: the European Maritime Safety Agency - EMSA tasked to contribute to the enhancement of the overall maritime safety system within the European Union and the European Union Satellite Centre – EUSC whose mission is to support the decision-making of the European Union by providing analysis of satellite imagery and collateral data. EUSC operates in the framework of the Common Security and Defence Policy. Furthermore A task is also dedicated to the technological development of a regional server for the EO service industry.

The project aims at supporting all the issues which arise when a decision process on the side of the (institutional) user, needs to exploit information based on EO data from multiple missions including high resolution commercial optical ones. One major project activity will focus on the feedback information on future satellite acquisitions, needed by planners on the institution side, for their routine operations. The need to act on specific events will also be addressed. Candidate technologies , architecture and interface control documents to the multi-mission ground segment and possibly the Sentinel one will be proposed.

Another large project activity will address the technologies and tools for the generation of up-to date cloud free coverage to be used as background information by EUSC.

The project will as well identify  and  collect desirable requirements over sensor, missions and data provision such as additional radar data for EMSA and in particular optical high resolution data for EUSC. On the basis of collected requirements, the project will be able to define the end-to-end scenarios for  assessing EO missions capabilities, ordering and retrieving EO products including from optical high resolution commercial missions. It will also prototype an end-to-end solution supporting relevant use-cases and requirements, taking into account available infrastructure within EUSC, EMSA and ESA. The project will demonstrate possible interfaces and components within the multi mission ground segment infrastructure in support the end-to-end scenarios.  Finally the project will identify gaps, and prototype improvements or evolutions in the above technologies components and interfaces.

Objectives

The objectives of the "Decision Support and Real Time EO Data Managements" (DREAM) project are to:

  • Collect and identify current and future requirements from EMSA and EUSC including needs in terms of sensors, missions and data provision and missions including ESA, TPM, or commercial.
  • Address technology, architecture and G/S interfaces needed to streamline:

    • planning, ordering and online data access to ESA and TPM
    • for two identified institutions: i.e. EMSA and EUSC
  • Exploit results of HMA standardisation activities.
  • Identify technology gaps and support evolution of technology and standards, e.g. by contributing specifications, implementations or participation to SWG and OGC Testbeds.

The DREAM project is organised in two phases.

Main Expected Results

The project expects to implement a prototype that:

  • Supports EUSC and the EMSA CleanSeaNet business scenarios
  • Demonstrates dynamic data transfer of EO data from PDGS to institutions decision support systems
  • Defines technical interfaces between components
  • Proposes interface to be exposed by the Sentinel 1 and 2 mission planning components to ensure future compatibility and “pluggability”
  • Ensures data integrity and traceability of quality and accuracy metadata throughout data transfer process
  • Takes into account available infrastructure and its future evolution including Sentinel PDGS-related projects ngEO and PDGS Evolution Framecontract
  • Includes candidate multi-mission PDGS services.

 
In addition, the project intends to contribute to HMA standardisation in the following areas:

  • Open-source implementation of Online Data Access Server.
  • Update of TEAM Engine.
  • Update of Conformance Test Language (CTL) Best Practice - OGC 06-126r2
  • Updated specifications related to on-line data access (EO WCS) and WCPS including:

    • WCS extension on band subsetting draft (OGC specification)
    • WCS extension on scaling draft (OGC specification)
    • WCS extension on interpolation draft (OGC specification)
    • WCS time series support draft (OGC specification)
    • revised GML Application Schema for Coverages standard draft (OGC specification)
    • revised WCS Core standard draft (OGC specification)
    • GeoTIFF, JPEG2000, CF-NetCDF encodings for coverages (contribution to OGC specification)
    • WCPS next-generation standard draft (OGC specification)
  • Updates to ESA EO CFI.
