Description: 

The Open Geospatial Consortium (OGC®) along with the International Association of Oil & Gas Producers (OGP) through the Geomatics Committee, IPIECA (the global oil and gas industry association for environmental and social issues) and Resource Data, Inc. have issued a Request for Information (RFI) to solicit input on an Oil Spill Response (OSR) Common Operating Picture (COP) recommended practice.


This RFI is part of the OGP/IPIECA Joint Industry Project to produce a recommended practice for GIS/Mapping in support of Oil Spill Response and for the use of GIS technology and geospatial information in forming a COP for management of the response.

Organizations are encouraged to respond with recommendations for procedures, technology, and open standards that should be considered in a recommended practice for an OSR COP. The RFI seeks input on three topics:

  • Defining a COP and its use for Oil Spill Response (OSR)
  • The scope of the geospatial information which shall be part of OSR COP
  • Formats, media and methods for delivering COP information to organizations involved in OSR 

Responses to the RFI should describe technologies and open standards feasible in a distributed information environment. A series of workshops is planned to discuss submitted RFI responses. Compilation of the RFI responses and the workshop outcomes will be documented in a report that can serve as the basis for consensus adoption of a standards-based COP best practice for OSR.

Rob Cox, IPIECA Technical Director said, “I anticipate the RFI process will be a basis for creating a COP recommended practice that will contribute greatly to globally coordinated operations for oil spill response.” 
Responses to the RFI are requested by 30 October 2013. The RFI includes instructions for how organizations can respond. Please contact George Percivall at gpercivall [at] opengeospatial.org with any questions.

 

The Open Geospatial Consortium (OGC)1 is an international consortium of more than 480 companies, government agencies, research organizations, and universities participating in a consensus process to develop publicly available geospatial standards. OGC standards support interoperable solutions that "geo-enable" the Web, wireless and location-based services, and mainstream IT. OGC standards empower technology developers to make geospatial information and services accessible and useful with any application that needs to be geospatially enabled.

The International Association of Oil & Gas producers (OGP)2 is a unique global forum in which members identify and share best practices to achieve improvements in every aspect of health, safety, the environment, security, social responsibility, engineering and operations. OGP encompasses most of the world's leading publicly-traded, private and state-owned oil & gas companies, industry associations and major upstream service companies. OGP members produce more than half the world's oil and about one third of its gas.

IPIECA3 is the global oil and gas industry association for environmental and social issues. IPIECA was formed in 1974 following the launch of the United Nations Environment Programme (UNEP). IPIECA is the only global association involving both the upstream and downstream oil and gas industry on environmental and social issues. IPIECA’s membership covers over half of the world’s oil production. IPIECA is the industry’s principal channel of communication with the United Nations. When IPIECA was set up in 1974 the acronym stood for the International Petroleum Industry Environmental Conservation Association. In 2009, recognizing that this no longer accurately reflected the breadth and scope of the association’s work, IPIECA stopped using the full title. The association is now known as IPIECA, the global oil and gas industry association for environmental and social issues.
Resource Data, Inc.4 (RDI) has been supporting the oil & gas industry with information technology for spill response since 1989. RDI brings unparalleled experience to oil spill response, leading the geographic information system (GIS) and database teams for the Exxon-Valdez spill and more recently the GIS response team in the Macondo/Deepwater Horizon spill. RDI has developed numerous spill response data systems, participated in multiple drills, and developed risk analysis systems for major pipeline networks. Our depth and breadth of expertise in spill preparedness and response uniquely positions RDI to assist in the development of a Common Operating Picture for the oil & gas industry.

OGC Calls for Participation in Climatology-Hydrology Information Sharing Pilot (CHISP-1)

Status: 
Please note: This Request is closed.
Closing Date: 
Fri, 09/14/2012 - 04:00
Description: 

 

The Open Geospatial Consortium (OGC®) has issued a Request for Quotations/Call for Participation (RFQ/CFP) to solicit proposals in response to requirements for the OGC Climatology-Hydrology Information Sharing Pilot (CHISP), Phase 1 (CHISP-1).

The RFQ/CFP is available at below.

Responses are due by 14 September, 2012.

A bidders’ teleconference was held on 15 August 2012. More information will be available below.

The Point of Contact is Lew Leinenweber (lleinenweber at opengeospatial.org).

The CHISP-1 sponsors are:

  • GeoConnections - Natural Resources Canada and Environment Canada
  • US Geological Survey (USGS)
  • US Environmental Protection Agency (EPA)

Around the world, there is a critical need for improved sharing, accessing, and integration of hydrologic and climatic data.  To meet that need, CHISP-1 will engage leaders in the hydro-climatic community to collaboratively build a duplicable system that uses existing resources – including data portals, standards, technologies, activities, and expertise. These resources are available to stakeholders in all countries.

CHISP-1 will create a virtual observatory system for water resources observations and forecasts in parts of the U.S. and Canada, building on current networks and capabilities to support:

  1. Hydrologic modeling of Milk River and Souris River for historical, current and future streamflow and inundation conditions.
  2. Modeling and assessment of nutrient flux into the Great Lakes, which requires accessing and integrating water quality data from multiple agencies

    Advantages of creating this system in an OGC Pilot Project include:

    • Management by a neutral organization
    • Use of a mature and trusted vendor-neutral process led by experienced administrative and technical project managers
    • Design and development best practices (iterative, agile approach to building a SOA-based system)
    • Inclusive process, with open, international call for participation from potential sponsors, and recruiting of industry's best and brightest to staff the development team.

      CHISP-1 will exercise OGC encoding and service standards, including the OGC WaterML 2.0 Encoding Standard, the OGC Sensor Observation Service (SOS) standard and others.

      CHISP-1 offers many benefits. In addition to leveraging the large body of existing related activities, those activities, and others like them around the world, will be enhanced by and benefit from the pilot outcomes. By pooling resources to accomplish a shared objective, the sponsors and participants in CHISP-1 reduce their development risks and leverage their investment. In addition to identifying and clarifying what is possible, the pilot will identify the key technical and non-technical barriers to continued progress in sharing and integrating hydrologic and climatic information. Because it is an international project with broad industry participation, it will promote understanding and strengthen ties within the existing hydro-climatic community.

      Overview

      The Open Geospatial Consortium (OGC®) has issued a Request for Quotations/Call for Participation (RFQ/CFP) to solicit proposals in response to requirements for the OGC Geo4NIEM Project. The Geo4NIEM Initiative will result in recommendations to enhance the geospatial capabilities within the National Information Exchange Model (NIEM). Sponsors have identified specific Information Exchange Packages (IEPs) from Department of Homeland Security (DHS), Justice/Law Enforcement domain, and the Maritime domain as representative examples for investigation in this initiative.

      The RFQ/CFP is available below. Deadline for submitting questions on the RFQ/CFP is 5pm EST on 21 February 2013. Responses are due by 5 pm EST on 4 March 2013.

      The Point of Contact is Lew Leinenweber: techdesk [at] opengeospatial.org.

      Geo4NIEM Initiative sponsors are:

      • Program Manager – Information Sharing Environment (PM-ISE)
      • National Information Exchange Model – Program Management Office (NIEM PMO)

      The focus of Geo4NIEM project will be to address requirements in the context of the following information exchange domain areas:

      Justice/Law Enforcement. The Justice/Law Enforcement domain in NIEM is defined by the Global Justice XML Data Model (Global JXDM). The Global Justice XML Data Model (Global JXDM) is an XML-based framework that enables the US justice and public safety communities to effectively share information at all levels.

      Maritime Domain Awareness. The Maritime domain supports the effective understanding of anything associated with global maritime that could impact the United States' security, safety, economy, or environment. NIEM facilitates this understanding through effective, timely sharing of vital, secure information among many key partners by representing vessels, people, cargo, and maritime locations and activities.

      The Geo4NIEM Project has been organized to address specific functional requirements to meet the following objectives:

      • Develop recommendations for the inclusion and standard use of embedded GML with NIEM IEP documents (IEPDs).
      • Develop recommendations for the standardized use of Naming and Design Rules and the use of adaptors (e.g. NIEM wrapper for GML).
      • Test and demonstrate use of a standardized embedded GML and adaptors within NIEM IEPDs.
      • Develop Architecture documentation and a fact sheet for the use of embedded GML and adaptors for use with NIEM IEPDs.
      • Develop Recommendations for the inclusion of a Geospatial Domain within NIEM.

        OGC Request for Information on "Contextual State Description" Services

        Status: 
        Please note: This Request is closed.
        Description: 

        Introduction

        With this Request for Information (RFI), The Open Geospatial Consortium Inc. (OGC) is soliciting input on technologies related to Contextual State Descriptions (CSD).  A CSD describes the "environment" or context in which a service chain executes. The objective of this request is to identify existing capabilities that can provide a robust metadata foundation for supporting agile, adaptive, autonomous processes capable of producing repeatable, predictable results with no intervention.

        In August, 2004, the Open Geospatial Consortium Inc. (OGC) issued a call for sponsors for an OGC Web Services 3 (OWS-3) interoperability initiative, a multi-threaded test bed activity to advance OGC's open framework for interoperability in the geospatial industry.  Key Components of OWS-3 will Sensor Web Enablement (SWE) and Service Chaining.  Each of these components are described below followed by some potential uses for CSD in OWS-3.

        Organizations with relevant technology regarding CSD are urged to respond to this RFI. Information on how to respond are at the end of this RFI.  The contents of the OWS-3 request for quotations (RFQ) will be based in part on the RFI response to the CSD RFI.

         

        Sensor Web Enablement and OpenGIS SensorWeb™

        A key component of OWS-3 will be Sensor Web Enablement (SWE), in which OGC members are developing standard interfaces and encodings that will enable real time integration of heterogeneous sensor webs into the information infrastructure. Developers will use these specifications in creating applications, platforms, and products involving web-connected devices such as flood gauges, air pollution monitors, stress gauges on bridges, mobile heart monitors, Webcams, and robots as well as space and airborne earth imaging devices. Several elements of SWE have already been developed and are being finalized before they are submitted to the OGC membership for adoption. CSD is a potential new element of SWE.

        OWS-3 will combine the previous work on SensorWeb with the OWS-2 Image Handling and Decision support results to provide automated workflow management to produce value-added products. SensorWeb is the source of tremendous amounts of geospatial data, e.g.,  in-situ, imagery and simulation data.  The Decision Support component of OWS-3 will continue the work of OWS-2 Service Chaining to produce value-added information products derived from SensorWeb data.

         

        Using CSD for Service Chaining

        A major thrust of OWS-2 was Image Handling for Decision Support. The Image Handling component of OWS-2 increased the ability to access and process geographic imagery into value-added products using open web services.  The Decision Support component of OWS-2 demonstrated automated service chaining of imager processing services.  This automation was achieved with an emerging open specification of workflow management: BPEL.

        This RFI seeks input on the technology related to Contextual State Descriptions (CSD).  A CSD could describe the "environment" or context in which a service chain "executes". A well-characterized service chain or workflow derives a repeatable result given equivalent sources, methods, and processing state or context.  A workflow script defines the order of service invocation in a service chain but the details of the services are hidden behind the web service interface. A CSD provides information about the distributed processing environment and resources that are hidden behind the interfaces.  A CSD is specifically designed to address environmental state descriptions, in such a manner that an equivalent state can be recreated at some future point to provide identical, repeatable results from a specified process, assuming identical sources, services and scripting are utilized.

        When workflows are manually executed and interpreted, complexity can be addressed through human intuition and experience.  However, in an autonomous environment, complexity must be distilled into codified states, before business logic can be characterized to facilitate autonomous processing with any level of confidence.  Thus, a CSD is specifically designed to facilitate the autonomous processing of complex workflows in a predictable, repeatable fashion.

        The promise of complex autonomous processing is the increased productivity of end user "analysts" that presently focus an inordinate amount of their time preparing data instead of analyzing it.  Thus, the transition of data into information into knowledge into some form of decision or course of action is largely still a manual process that cannot be reliably repeated.  True autonomous processing will not determine the ultimate course of action from a workflow, but can relieve the analyst from having to manually shepherd data through this workflow process, freeing them to focus on interpreting the derived knowledge into alternative courses of action in less time than the current process requires to develop a single course of action manually.

        CSD does not describe the workflow business logic, but the contextual state that the workflow executes within.  Thus, the CSD would describe the systems configuration, the hardware configuration, the firmware used by each device, the operating system, including patches, the software configuration, including external dependencies (shared libraries), and any data.  All of this information characterizes the operational state or context of the system. Any change in this contextual state may result in discrepancies when the workflow is re-executed.

         

        Potential use for CSD in OWS3

        OWS-3 will apply service chaining to enable use of SensorWeb technologies for decision support.  This technology will allow sensor measurements and modeling predictions to be processed into higher-value information specific to a given decision making context.  CSD may be used to capture the state of the service chain including the SensorWeb components and the geo-processing services and the workflow management components.  Capturing this information in a CSD will allow for post-processing analysis of the decision support information.

        For instance, this initiative could describe each of the sensor components of the current SensorWeb, as well as a corresponding set of metadata to describe the processing chain.  Quality metrics embedded within the data stream can describe the resultant accuracies associated with any point in the stream.  However, when a degraded signal is recorded within the sensor stream, there is no context to interpret the cause and effort on the resulting value-added information.  The CSD associated with this process could describe the environmental context or state that the SensorWeb was operating within to illustrate the reason for the degraded decision support information.

        Due to the potential iterative nature of CSDs, a normalizing relationship structure must be provided to "relate" voluminous descriptive metadata references, without requiring these references to be redundantly embedded within a single CSD.  Several compelling technologies and standards currently exist to address these specific issues.  The net result of an CSD-enabled workflow would be a greater understanding of the situational context present when the SensorWeb was captured.  These concepts are not new and have often been referred to as "fusion", multi-INT/multi-Source, and/or horizontal integration.

        CSD could be applied to the OWS-2 Image Handling results including automated image orthorectification.  In OWS-2, the orthorectification was accessible by a single web service request without exposing the underlying processing hardware.  While retaining this simple web service interface, CSD could be used to capture a description of the underlying processing environment.  For example, orthorectification may be performed by a cluster-based computing task with the processing load distributed across all available nodes in the cluster.  Depending upon the load on the system, the number of nodes available during processing time, the system resources allocated to each node and the system, the methods and availability of source materials (raw imagery and control information), and the business logic applied to the process (tiling inputs, parallel vs. serial processing, types of control applied), the resultant orthorectified images will be created with varying degrees of accuracies and latencies.  Once sufficiently populated, these accuracies and latencies (CSDs) can be mined to support the development of an adaptive system, whereby an orthorectification request can be fulfilled based on the degrees of freedom provided by varying the accuracies or latency in the fulfillment of this request.

         

        Objective Requirements

        The objective of this RFI is to identify existing capabilities that can provide a robust metadata foundation for supporting agile, adaptive, autonomous processes capable of producing repeatable, predictable results with no intervention.  These objectives are purposely abstracted to describe a wide variety of processes or workflows, beyond just computer system processes.

        A CSD shall describe the contextual state of a process or workflow. The structure of a CSD shall be such that a subsequent re-execution of a specified process will generate equivalent results, assuming the state from which the original process executed can be faithfully replicated.  A CSD shall be capable of relating or referencing other external processes, services, or data as part of a contextual state.  External references embedded within a CSD should not require the inclusion of the full reference, but rather a form of relation that will support normalized, iterative references.  CSD shall not be explicitly tied to computer system processes or workflows, but must support a much broader, abstracted description of a process and/or workflow.

        CSD is information, i.e., metadata, about the processing environment. OGC has adopted and implemented ISO 19115:2003, Geographic Information - Metadata in OGC Abstract Specification, Topic 11 - Metadata. While ISO 19115 is primarily for the description of datasets, it includes metadata to describe the processing history of a dataset.  While the objectives of CSD exceed the elements in ISO 19115, CSD implementations must utilize elements of ISO 19115 when appropriate in lieu of defining new terms for the same concept.

        Methodologies need to be developed to couple CSDs with processes and workflows as logical metadata structures.  Methodologies need to be provided to extract the contextual state from a system, process or workflow and codify that state within a specified CSD. Additional methodologies need to be provided to extract a contextual state from a CSD to reconfigure (to the extent physically possible) a described system capable of re-executing the process or workflow associated with the CSD.  Methods need to be developed that can identify and codify the differences between two CSDs, forming the basis for determining whether two CSDs are essentially equivalent.  A CSD shall be capable of being described in a service context that will facilitate autonomous processing of CSD attributed processes and workflows.

        OGC Request for Quotation for Empire Challenge 08 Pilot

        Status: 

         

        Slides for the Bidders Conference on 16 January are now available.

        Description: 

        The Open Geospatial Consortium, Inc. (OGC) has issued a Request For Quotations and Call for Participation (RFQ/CFP) to solicit proposals in response to requirements for the Empire Challenge 08 Pilot (EC08 OGC Pilot).

        The EC08 OGC Pilot is sponsored by a US agency which will provide cost-sharing funds to offset expenses associated with the initiative. The sponsor and the OGC intend to involve as many participants in the initiative as possible and thus are soliciting proposals that will enhance and/or make use of the initiative outcomes. This RFQ/CFP is soliciting partners to provide and deploy hardware / software and to collaborate on the final technology design for the pilot network. Personnel without clearances will be able to install and maintain software on the network. Responses are due by January 24, 2008 and the Pilot Kickoff Meeting will be held the week of February 26-28, 2008, in the Washington, DC area. Technology deployments will be complete by June 27, 2008, followed by a four-week demonstration phase in July.

        The EC08 OGC Pilot will examine the suitability and performance of OGC Sensor Web Enablement (SWE) and OGC Web Services (OWS) standards for providing open management of and access to sensors of varied types and Web service access by analysts to the resulting data and products. Several use cases and supporting workflows are provided to enable understanding of the design of the pilot. The use cases involve both sensor management and exploitation by a targeting analyst.

        Description: 

        The Open Geospatial Consortium (OGC®) seeks public comment on the candidate Earth Observation profile for the OGC Web Coverage Service (WCS) 2.0 standard. This profile will facilitate on-line data access to Earth Observation data products.

        The OGC WCS 2.0 standard defines a general interface and operations that enable interoperable access to geospatial coverages, such as sensor data, satellite imagery, digital elevation models, and climate/ocean data. The candidate OGC Web Coverage Service Application Profile for Earth Observation products (EO-WCS) defines an interface for interoperable access to Earth Observation data.

        The rapid increase of computer power and network accessibility, along with implementations of the OGC WCS standard, make it possible for applications to deliver user selected sensor, image, and statistics data, including human modifications of the Earth's surface and atmosphere. As use of the standard increases, an increasingly wide variety of data will conveniently be brought together in applications such as environment, natural resources, planning, disaster management and public security.

        The candidate Earth Observation profile for the OGC Web Coverage Service (WCS) 2.0 standard documents are available for review and comment below.
