Notes de l'éditeur
- DIB Applications - External Tasking, Mission Management, Distributed Sensor Planner Sensor Planning Service Provides a standard interface for planning and tasking sensors. SPS interface operations include: DescribeCollectionRequest() GetFeasibility() SubmitRequest() UpdateRequest() CancelRequest() GetStatus() ACTM – Airborne Common Tasking Message Created to reflect the tasking information used by all DoD and IC platforms. Provided as input to OWS-3 in support of the SPS maturation. Sensor Alert Service Under development in an OGC Interoperability Experiment
- SWE web services: Sensor Observation Service – Access to sensor or simulated data Sensor Planning Service – Sensor System or Simulator Control Interface Sensor Alert Service – Subscribe to specific alerts usually derived from sensor/simulator data Catalog Service – Discover other services, sensors, providers and data sets SWE Steps: Services are first registered in one or several catalogs also accessible through a standard interface. Client can discover services, provider, sensors and datasets by using the catalog Client can then access data from SOS, control sensors and simulators using SPS and receive alerts from SAS
- 8 October 2010 Beware: these are simply hilights. The illustration is not really correct for the baseline, and possibly too simple for final pilot!
- This slide shows an OGC system framework being used for Satellite and Field Integration. We have tested an interoperability connection to Rain Gauge SOS from GIS.FCU Taiwan. The GSMaP (Global Rainfall Map) which is a near real-time hourly rainfall map will be accessed via WMS connection from GEO Grid, AIST, Japan. The validation process will be done by WPS.
- As geographic content (geodata) and services become more widely available in digital form over ubiquitous networks, data becomes easier to distribute, share, copy and alter. While this is generally a good thing, many organizations involved in the production and trading of geodata find the need to protect their Intellectual Property (IP) assets through the digital distribution value chain. Organizations want to specify, manage, control and track geodata distribution within secure, open and trusted environments. A system of operating agreements and interoperable technologies are needed to enable broader distribution and use of geodata while protecting the rights of producers and users. In or e-commerce models for dissemination and use of Intellectual Property (IP) assets, geodata are treated as commodities to be priced, ordered, traded and licensed. Direct monetary reward, however, is often not the motivation or is only secondary behind the desire for more rigorous control of IP assets. Harlan Onsrud of the GeoData Alliance argues that the incentive structures implicit in “library systems” are an appropriate model for motivating data producers, collectors and traders to document, share and otherwise disseminate their geodata. Onsrud observes that the library system is a “chaordic” framework of seemingly ad hoc agreements among stakeholders that strikes a balance supporting “…strong public goods, access and equity principles while fully protecting the intellectual property rights of authors and publishers.” http://portal.opengeospatial.org/files/?artifact_id=14085
