Technical Committee

Chair(s):

Reed III, Carl (Reed, Carl)
Simmons, Scott (Open Geospatial Consortium, Inc.)

Group Description:

The OGC membership process is operationally organized into groups and subgroups, each group having a specified role and level of responsibility. There are three major groups, called Committees: The Technical, the Planning and the Strategic Management Advisory Committees.

The Technical Committee is responsible for all aspects of the formal consensus OGC specification process. This includes:

Planning Committee

Chair(s):

Simmons, Scott (Open Geospatial Consortium, Inc.)

Group Description:

The OGC Planning Committee is granted authority to operate by the OGC Bylaws. Principal Membership is provided for organizations that wish to participate in the planning and management of the Consortium's technology development process.

The Planning Committee has ultimate responsibility for approving Technical Committee recommendations for the adoption and release of OGC standards, and for Specification Program planning.

Strategic Member Advisory Committee

Chair(s):

No Chairs Identified

Group Description:

The Strategic Member Advisory Committee is conceived to be a permanent committee within the OGC organization, designed specifically to provide Strategic Members the opportunity to participate in the strategic planning processes of the Consortium, and to support Consortium operations aimed at achieving the corporation's mission as defined in the bylaws.

Climate-Hydrologic Information Sharing Pilot Sponsors

 
What is it?  An inter-disciplinary, inter-agency and international virtual observatory system for water resources information from observations and forecasts in the U.S. and Canada, building on current networks and capabilities, designed to support these functions:

  • Hydrologic modeling for historical and current stream flow and groundwater conditions.  Requires the integration of trans-boundary stream flow and groundwater well data, as well as national river networks (US NHD and Canada NHN) from multiple agencies.  Emphasis on time series data and real-time flood monitoring.
  • Modeling and assessment of nutrient load into the lakes.  Requires accessing water-quality data from multiple agencies and integrating with stream flow information for calculating loads.  Emphasis on discrete sampled water quality observations, linking those to specific NHD stream reaches and catchments, and additional metadata for sampled data. 
  • Collection and preservation of provenance, uncertainty measures, and other metadata throughout processing workflows.

Key objectives of these use cases are:

  1. To link observations data to the stream network, enabling queries of conditions upstream from a given location to return all relevant gages and well locations. This is currently not practical with the data sources available.
  2. To bridge differences in semantics across information models and processes used by the various data producers, to improve the hydrologic and water quality modeling capabilities.

 
Why do it now?  Improved capabilities for sharing, accessing, and integrating hydrologic and climatic data have been identified as a critical need for some time.  We are at a point in time at which an opportunity exists to make large steps forward by leveraging existing resources – including data portals, standards, technologies, activities, and expertise – to develop an initial operational capability for the system described above.  
 
Expected Benefits

  • Leverage a large body of existing data holdings and related activities of multiple agencies in the US and Canada.
  • Influence data and metadata standards used internationally for web-based information sharing, through multiple agency cooperation and OGC standards setting process.
  • Reduction of procurement risk through partnership-based development of an initial operating capability verses ~10x the cost for building a fully operational system using a traditional “waterfall approach”.
  • Identification and clarification of what is possible, and of the key technical and non-technical barriers to continued progress in sharing and integrating hydrologic and climatic information.
  • Promote understanding and strengthen ties within the hydro-climatic community. This is anticipated to be the first phase of a multi-phase project, with future work on forecasting the hydrologic consequences of extreme weather events, and enabling more sophisticated water quality modeling.

 
Plan

  • Release Request for Quotation / Call for Participation (RFQ/CFP)
  • Proposals due
  • Project Kickoff Meeting, Washington DC area
  • Completion of development and engineering reports

 
 

OGC® Open Modelling Interface (OpenMI) Interface Standard

The purpose of the Open Modelling Interface (OpenMI) is to enable the runtime exchange of data between process simulation models and also between models and other modelling tools such as databases and analytical and visualization applications. Its creation has been driven by the need to understand how processes interact and to predict the likely outcomes of those interactions under given conditions. A key design aim has been to bring about interoperability between independently developed modelling components, where those components may originate from any discipline or supplier. The ultimate...
