GEOSSThe System of Systems Approach

Where a system is a collection of components

www.meraka.org.za 20/04/23 / 4

System Overview Open Systems

Permeable Boundaries

React to Environment

Closed Systems Solid Boundaries

No External Interaction

GEOSS Systems View Systems contributing to GEOSS may be

Open or Closed GEOSS itself must be an Open System

Interoperability

React to environment (Adaptability)

Increases survivability

Open System Architecture Computer System

Interoperability within the system

Portability from one platform to another

Open standards

Sensor Web Definition

“Group of potentially muti-modal data gathering devices coupled with computational intelligence and

communication such that the overall system capabilities transcend those

provided by a group of isolated sensors” (John M. Dolan 2007)

Sensor Web Open System

Interoperable, portable and open standards

Computational Intelligence Collaborative Value beyond the individual component

Data Fusion

Sensor Web Approaches Sensor Web Agent Platform (SWAP)

Multi Agent Approach

OGC Sensor Web Enablement (SWE) Service Oriented Approach

Hourglass Peer 2 Peer Approach

OGC SWE SWE is not a Sensor Web

SWE enables the creation of a Sensor Web

Provides Open Standards Portability is available through SOA Interoperability

Across heterogeneous platforms

www.meraka.org.za 20/04/23 / 12

OGC SWE Lacks computational intelligence

AI may be built into services

Collaboration is not inherent Provides the mechanism for collaboration

Once service combined we can start to provide value beyond the individual

OGC SWE Framework Objectives

Discover sensors, observations & processes

Determination of capabilities and reliability

Retrieve real-time or time-series data

Task sensors and simulators

OGC SWE Framework Supporting Standards

Sensor Observation Service (SOS)

Sensor Alerting Service (SAS) use (WNS)

Sensor Planning Service (SPS)

GEOSS and OGC SWE GEOSS requires open system, OGC SWE is

an open architecture OGC SWE not the only option OGC SWE is an easy step in the right

direction

DA-07-04

Sensor Web Enablement for In-Situ Observing Network Facilitation

www.meraka.org.za 20/04/23 / 20

Description

Development of scenarios or use cases that demonstrate the value of Sensor Webs to the

GEOSS SBAs. Specific domains that can benefit from Sensor Web are for instance Disasters, Health, Biodiversity, Ecosystem

and Water.

www.meraka.org.za 20/04/23 / 21

ActivitiesA geospatial information infrastructure connecting heterogeneous in-situ sensors and remote sensors, shall be defined. This includes the definition and design of the Sensor Web Communication- and Information layers.

The Task should evaluate the applicable standards for the application of a Sensor Web based approach for the different GEO SBAs

To provide a mechanism to register and categorise Web services, a service registry shall be investigated.

www.meraka.org.za 20/04/23 / 22

ActivitiesCase studies shall be designed as demonstration projects for at least 3 SBAs

Coordination shall be established with the Interoperability arrangements for GEOSS through coordination with Tasks AR-07-01 and AR-07-02

Relevant synergies with other GEOSS Tasks shall be addressed
