Using satellite data in disaster management and risk assessment

Using Satellite Data in Disaster Management and Risk Assessment

WGISS

People – Sensors – Data – Processes – Decision Support


Using satellite data in disaster management and risk assessment1

WGISS-32 – Budapest, Hungary

Using Satellite Data in Disaster Management and Risk Assessment

  • Involves coordination and linking among

    • Activities of many Independent Parties

    • Different Contexts / Communities of Practice

      • Esp. Vocabulary & Semantics

      • Also Linguistic, Cultural, Economic, Political differences

    • Decisions and Operations using Satellite Data

      • => Greater Effectiveness; Greater Efficiency

  • Requires a shared, precise understanding of

    • Disaster Management and Risk Assessment processes (decisions, operations, etc.)

    • How those processes use (or could use) complex data streams from satellites

What s an enterprise architecture

WGISS-32 – Budapest, Hungary

What's an Enterprise Architecture?

  • “A conceptual blueprint that defines the structure and operation of an organization ... to determine how [it] can most effectively achieve its current and future objectives.” (Wikipedia)

  • “A framework for understanding significant relationships among the entities of some environment, and for the development of consistent standards... based on a small number of unifying concepts … may be used as a basis for education and explaining standards to a non-specialist. (ORCHESTRA Ref. Model)

  • “A management practice for aligning resources to improve business performance and help agencies better execute their core missions” (US Federal Enterprise Architecture)

  • “A framework for ensuring IT investments enable the mission and are integrated, efficient and secure” (NASA)


Enterprise architecture vs reference model

WGISS-32 – Budapest, Hungary

Enterprise Architecturevs. Reference Model

  • An Enterprise Architecture describes the structure of an enterprise, including the business entities, their properties and behavior, and the relationships between these entities.

  • A Reference Model is a conceptual, technology-independent description of entities and relationships within a given environment. It includes a clear description of the problem to be solved, and the concerns of the stakeholders who need the problem solved.

  • These are interchangeable for our purposes – at least for now


What s an enterprise architecture1

WGISS-32 – Budapest, Hungary

What's an Enterprise Architecture?

  • An enterprise architecture (/ reference model) is:

    • Guidance, not a fully detailed plan or blueprint

    • A tool, not a policy

    • A living document – not a fixed specification

  • Provides a logical rather than a physical view

    • Articulates a shared understanding of

      • Needed functions and

      • End-to-end data flows

    • But doesn’t attempt to create inventories of deployed resources


What is the enterprise

WGISS-32 – Budapest, Hungary

What is the Enterprise?

  • One starting point: GEOSS DI-06-09 charter (Use of Satellites for Risk Management):

    • Reducing loss of life and property from natural and human-induced disasters

    • More specifically: “Define and facilitate implementation of satellite constellations for risk management from a multi-hazard perspective. Undertake the consolidation of the validated requirements and examine options for system development and implementation.”


Requirements for our enterprise architecture reference model

WGISS-32 – Budapest, Hungary

Requirements for our Enterprise Architecture / Reference Model

  • Allow for regional differences – policies, economics, language, etc.

    • Not an abstract, one-size-fits-all architecture

  • Allow for a variety of types of disasters

  • Support both disaster response and risk assessment

  • Build on / be consistent with existing architectures and semantics

    • GEOSS Architecture Implementation Pilot - AIP3

    • GEOSS 10-Year Action Plan

    • UN-SPIDER

    • International Charter; others?


Building an enterprise architecture architecture frameworks

WGISS-32 – Budapest, Hungary

Building an Enterprise Architecture: Architecture Frameworks

  • An Architecture Framework defines levels, layers, or views used in constructing an enterprise architecture or reference model

    • e.g., Business / Applications / Data / Technology


Architecture frameworks

WGISS-32 – Budapest, Hungary

Architecture Frameworks

  • ISO/IEC Reference Model for Open Distributed Processing (RM-ODP)

  • Seems like a good fit here:

    • Distributed data handling

    • Open systems approach

    • Used by related enterprise architectures:

      • GEOSS Architecture Implementation Pilot (AIP-3)

      • ORCHESTRA (European Union - Service Oriented Architecture for EU Risk Management)

      • INSPIRE (Infrastructure for Spatial Information in Europe)

Enterprise viewpoint

WGISS-32 – Budapest, Hungary

Enterprise Viewpoint

  • Enterprise questions to be addressed for GA4D:

    • What are the purpose and scope for the use of satellite data in Disaster Management and Risk Assessment?

    • What activities are involved?

    • In what organizational structures do (or must) these activities take place?

    • Who are the participants in these activities?

    • Who are the stakeholders for this architecture – who has (or should have) a say in how these activities draw on information from satellites (and elsewhere)?

    • What other enterprises are linked to this one?

    • Include Roles

    • Use cases

Scope


Information viewpoint

WGISS-32 – Budapest, Hungary

Information Viewpoint

  • Information questions to be addressed for GA4D:

    • What observations or parameters are needed when responding to different kinds of disasters (or assessing their risk)?

    • In what forms does this information best support the enterprise?

    • What metadata are needed to ensure that data can be found and appropriately used?

    • What inter-dependencies exist among these data products?

    • What data transformations, interpretations, extractions, syntheses, etc. are needed between sensors and users?


Information viewpoint1

Information Viewpoint

  • Observations types vs. Societal Benefit Areas

From GEO Task US-09-01a

Critical Earth Observation Priorities

Summary of Results • October 2010


Information viewpoint2

WGISS-32 – Budapest, Hungary

Information Viewpoint

  • Observations types vs. Disaster Types

From GEO 10-Year Implementation Plan Reference Document • February 2005


Computation viewpoint

WGISS-32 – Budapest, Hungary

Computation Viewpoint

  • Information questions to be addressed for GA4D:

    • What service types are needed to make the necessary information available to users?(e.g., data access, visualization, catalog search)

    • How will these service types effect the data transformations, interpretations, extractions, syntheses, etc. that are needed between sensors and users?

    • What requirements apply to these services and interfaces (e.g., near-real-time performance, cross-community interoperability)


Engineering viewpoint and technology viewpoint

WGISS-32 – Budapest, Hungary

Engineering Viewpointand Technology Viewpoint

  • Engineering questions to be addressed for GA4D:

    • What interface types are needed to invoke the services described in the computation viewpoint? (e.g., stateless / stateful; pull / push)

    • What interface standards are needed to support interoperation between different communities?

  • Technology questions to be addressed for GA4D:

    • What satellite data streams are available? Needed?

    • What catalogs are available? Needed?
