OGC Requests

Call for Participation in NGA “Plug Week” Pilot

Status: 
Please note: This Request is scheduled to close on 3 August 2009.
Description: 
July 13, 2009. The Open Geospatial Consortium, Inc. has issued a Request For Quotation and Call for Participation (RFQ/CFP) to solicit proposals for the NSG Profiles Plugweek Pilot, which will begin in August and end in October. (NSG is the National System for Geospatial Intelligence.) The sponsor, the National Geospatial-Intelligence Agency (NGA), will provide profiles of the OGC Web Map Service, Web Feature Service and Web Coverage Service Interface Standards.

With the help of Plugweek participants, the NGA will examine the suitability and performance of these profiles and corresponding profile compliance tests. The NGA is providing cost-sharing funds and seeks to involve as many participants as possible.

The RFQ/CFP invites prospective participants to submit proposals for providing and deploying hardware and software and contributing to the final technology suite for the test network. The sponsor will decide which submitters will be offered cost-sharing funds. Participants will use the profiles mentioned above and also schemas and data provided by the NGA.

NSG Profiles Plugweek is an opportunity for vendors, users, and other interested parties to mutually refine services, interfaces and protocols in the context of a hands-on engineering experience that is intended to shape the future of the NGA's web based information distribution systems. Another benefit is that this effort has well-defined objectives, while providing a significant opportunity to explore alternatives in a unique hands-on engineering context.

Instructions for submitting proposals are provided in the RFQ/CFP. Proposals are due by August 3, 2009. Non-member proposals will be considered if a completed application for OGC membership accompanies or precedes a letter of intent to submit a proposal.


OGC Requests: 

OGC Calls for Comment on revision to OGC Web Services Common Standard

Status: 
Please note: This Request is scheduled to closed on 20 May 2009.
Description: 
The members of the Open Geospatial Consortium, Inc. (OGC®) request comments to a revision to the OpenGIS® Web Services Common Standard. This document specifies many of the aspects that are common to multiple OGC Web Service (OWS) interface Implementation Standards. These common aspects are primarily parameters and data structures used in operation requests and responses. Examples of common usage are how to handle bounding boxes, exception processing, URL requests, URN expressions, key value encoding, and so forth.

The primary use of OWS Common is as a normative reference for other OWS standards. Those standards currently include the OpenGIS Web Map Service (WMS), Web Feature Service (WFS), and Web Coverage Service (WCS) Standards. Rather than continuing to repeat this material in each Implementation Standard, each standard normatively references each relevant part of OWS Common.

The 30 day public comment period begins April 20, 2009 and closes on May 20, 2009. Comments will be reviewed and processed by the OGC Membership. The intent is to edit the OWS Common standard and move the revised document to be an approved OGC standard. The OpenGIS® Web Services Common Standard Request for Comment document can be downloaded below.

OGC Requests: 

Request for Comments (RFC) on Candidate Specification Model Standard

Status: 
Please note: This Request is closed. The documents listed below have been adopted by the OGC Technical and Planning Committee. These specifications are under control of the specification Revision Working Group and will be released after the edits and revisions. For the most current version please check our Standards Page.
Description: 

The membership of the Open Geospatial Consortium, Inc. (OGC) is requesting comments from the public on the candidate OGC Document, "The OGC Specification Model - Writing Modular Specifications".

This document, prepared by the Policy 1.0 Standards Working Group, derives from the collective experience of members in developing and implementing OGC standards, geospatial applications, platforms and services. It provides a logical model and template for candidate standards to assure their internal logic and conformance to accepted software development procedures and the OGC's policy and rules regarding the structure of standards and the types of information that they must provide. The policy guidance will make implementation of OGC standards and the construction of compliance tests easier through enforced traceability of requirements to implementation tests, and it will make modularization of both standards and implementations more explicit and consistent across dependent standards and implementations.

This standard has been referred to as the "core and extension model" due to the insistence on a modular structure throughout all parts of a standard and its implementation. Eventually, all OGC standards will be transitioned to the new structure. This will help standardize the manner in which OGC standards are written and implemented, making implementations easier to test for compliance, thus improving interoperability between and swap-ability between implementations.

The 30 day public comment period begins March 12, 2009 and closes on April 11, 2009. Comments will be reviewed and processed by the OGC Membership. The intent is to edit the Specification Model candidate standard and move the document to be an approved OGC standard. The Specification Model Request for Comment document can be downloaded below.

Request for Comments on Candidate Web Map Tiling Standard

Status: 
Please note: This Request is closed. The documents listed below have been adopted by the OGC Technical and Planning Committee. These specifications are under control of the specification Revision Working Group and will be released after the edits and revisions. For the most current version please check our Standards Page.
Description: 

The membership of the Open Geospatial Consortium, Inc. (OGC®) is requesting comments from the public on the candidate OpenGIS® Web Map Tiling Service (WMTS) Interface Standard.

The candidate WMTS Interface Standard is much like the OGC's popular Web Map Server (WMS) Interface Standard, but it enables better server performance in applications that involve many simultaneous requests. To improve performance, instead of creating a new image for each request, it returns small pre-generated images (e.g., PNG or JPEG) or reuses identical previous requests that follow a discrete set of tile matrices. This proposed standard provides support for multiple architectural patterns - KVP, REST and SOAP.

The 30 day public comment period for this document begins February 26, 2009. Comments are due by March 29, 2009. After the OGC's WMS Standards Working Group has addressed comments received in response to the WMTS RFC the draft documents will be submitted to the OGC Technical Committee and Planning Committee for their review and possible approval as an adopted OGC Standard.

Request for Comments (RFC) on the GeoLinking Service Standard

Status: 
Please note: This Request is closed. The documents listed below have been adopted by the OGC Technical and Planning Committee. These specifications are under control of the specification Revision Working Group and will be released after the edits and revisions. For the most current version please check our Standards Page.
Description: 

The membership of the Open Geospatial Consortium, Inc. (OGC) is requesting comments on the candidate standard OpenGIS(R) GeoLinking Service (GLS) Interface.

The candidate GLS standard defines an interface for services that provide the ability to "link" data that contain information about geographic objects, such as census tract population statistics, with data in another repository that contains the actual geometry (points, lines, polygons). For example, a table of populations of cities on one server may not contain the geometry information that describes the cities' locations and boundaries, while a second server may house the cities' geometry. The candidate GLS standard describes a set of interfaces for both servers that lets the city name be used as a "common geographic identifier" to join the population data to its geometry, so the user can create a map or perform geospatial analysis on the linked data.

OGC Web Services, Phase 6 (OWS-6) Request For Quotation and Call For Participation

Status: 
Please note:  As of October 31, this Request is CLOSED to further proposals.
Description: 
RFQ Issuance Date: 21 July 2008
OWS-6 Bidder's Conference: 8 August 2008
Proposal Due Date: 5 September 2008

 


Overview

OWS testbeds are part of OGC's Interoperability Program, a global, hands-on and collaborative prototyping program designed to rapidly develop, test and deliver proven candidate specifications into OGC's Specification Program, where they are formalized for public release. In OGC's Interoperability Initiatives, international teams of technology providers work together to solve specific geoprocessing interoperability problems posed by the Initiative's sponsoring organizations. OGC Interoperability Initiatives include test beds, pilot projects, interoperability experiments and interoperability support services - all designed to encourage rapid development, testing, validation and adoption of OGC standards.

The OWS-6 sponsors are organizations seeking open standards for their interoperability requirements. After analyzing their requirements, the OGC Interoperability Team recommended to the sponsors that the content of the OWS-6 initiative be organized around the following threads:

  1. Sensor Web Enablement (SWE)
  2. Geo Processing Workflow (GPW)
  3. Aeronautical Information Management (AIM)
  4. Decision Support Services (DSS)
  5. Compliance Testing (CITE)

OWS-6 Sponsors

  • U.S. National Geospatial-Intelligence Agency (NGA)
  • Joint Program Executive Office for Chemical and Biological Defense (JPEO-CBD)
  • GeoConnections - Natural Resources Canada
  • U.S. Federal Aviation Agency (FAA)
  • EUROCONTROL
  • EADS Defence and Communications Systems
  • US Geological Survey
  • Lockheed Martin
  • BAE Systems
  • ERDAS, Inc.

OWS-6 Threads

1) Sensor Web Enablement (SWE)

The OGC Sensor Web Enablement framework has achieved a degree of maturity through previous OWS interoperability initiatives and deployments worldwide. OWS-6 will focus on integrating the SWE interfaces and encodings into cross-thread scenarios and workflows to demonstrate the ability of SWE specifications to support operational needs. Emphasis for SWE during this phase of the OWS test-bed will be on:

  • CCSI-Enabled CBRN Sensors into the SWE Environment
  • Build on Georeferenceable imagery accomplishments of OWS-5
  • Harmonize SWE-related information models: SensorML, GML, UncertML, MathML
  • Apply GeoRM, Trusted Services, and security models in SWE environment
  • Events-based architecture including WNS

2) Geo Processing Workflow (GPW)

This GPW thread aims to build on the progress of previous testbeds with a focus on maturing the interoperability and capabilities of OGC web services in a service-oriented architecture with particular emphasis to address OGC web service security issues. To satisfy mission-critical goals, the architecture must not only provide for integration of a wide variety of service capabilities and resources, it must do so and ensure authenticity, integrity, quality and confidentiality of services and information. To meet these goals, the following task areas have been identified:

  • Asynchronous Workflow and Web Services Security
  • Data Security for OGC web services
  • Data Accessibility
  • WPS Profiles - Conflation; and Grid processing
  • GML Application Schema Development & ShapeChange Enhancements

3) Aeronautical Information Management (AIM)

The Aviation Information Management (AIM) subtask is a new thread within OWS to develop and demonstrate the use of the Aeronautical Information Exchange Model (AIXM) in an OGC Web Services environment. The AIM subtask shall focus on evaluating and advancing various AIXM features in a realistic trans-Atlantic aviation scenario setting by devising and prototyping a Web Services Architecture for providing valuable aeronautical information directly to flight decks, Electronic Flight Bags (EFB) and hand-held devices (such as PDAs and Blackberries) while the airplane is at the gate or en-route to its destination (for the purposes of OWS-6, the aeronautical information in the latter case does not depend on the knowledge of the airplane's location).

AIXM was developed by the Federal Aviation Administration (FAA) and Eurocontrol as a global standard for the representation and exchange of aeronautical information. It was designed as a basis for digital aeronautical information exchange and for enabling the transition to a net-centric, global aeronautical management capability. AIXM has been developed using the ISO 19100 modeling framework and has two major components: a conceptual model presented in the form of an UML class model and a data encoding specification which was developed using the OGC Geography Markup Language (GML). Both have been tailored to the specific requirements for the representation of aeronautical objects, especially the temporality feature that allows for time-dependent changes affecting AIXM features. More information about AIXM is available on www.aixm.aero. In support of the above objectives, the OWS-6 AIM thread shall perform tasks in the following areas while ensuring that the integrity of data is preserved throughout all data exchange operations:

  • Use and enhancement of Web Feature Service and Filter Encoding specifications in support of AIXM features and 4-dimensional flight trajectory queries,
  • Prototype of Aviation client for retrieval and seamless visualization of AIXM, Weather and other aviation-related data, emphasizing time and spatial filtering in order to present just the right information into a given user context anytime, anywhere,
  • Architecture of standards-based mechanism to notify users of changes to user-selected aeronautical information.

4) Decision Support Services (DSS)

Decision Support Services having an emphasis on applications of geospatial and temporal information has been a recurring thread in previous OWS testbeds. This thread focuses on presenting and interacting with data obtained from the sensor web and geoprocessing workflows in the most effective ways to support analysis and decision making. The focus for DSS in OWS-6 builds on portrayal, WMS Tiling, and integrated client work from OWS-4, with additional work on 3D visualization and integration of the built environment and landscape. This thread will encompass these capabilities and task areas:

  • ISO 19117 and OGC SLD Portrayal
  • 3D Portrayal of GML with Fly-through
  • Hosting CityGML data with WFS
  • Outdoor and indoor 3D route and tracking services
  • WMS performance (tiling)
  • Integrated Client for multiple OWS services

5) Compliance Testing (CITE)

Validating compliance with an OGC specification means verifying that a software product has implemented the specification correctly by testing the software interface for response and behavior that is outlined in the specification. Verifying compliance to the standard is necessary in order to achieve interoperability. As a result, geospatial application vendors desire to provide their potential costumers a means to verify adherence to OGC standards as a measurable discriminator for the interoperability of software products. Similarly, users desire assurance that acquired software components will interoperate with their existing investments in OGC-compliant technology. The Conformance and Interoperability Test and Evaluation (CITE) thread is intended to provide the geospatial industry (consumers and vendors) a methodology and tools that will test compliance with OGC web services.

The OGC Interoperability Program and the OGC Specification Program have achieved a great deal of momentum as a result of the multiple OGC web service specifications that have recently been published. Key consumers in the geospatial industry are modernizing their enterprises based on the applicability and interoperability of OGC web services. The major geospatial industry consumers require verifiable proof of compliance with OGC specifications in order to reach the desirable outcome of interoperability. Furthermore, as the OGC technology stack has matured, a group of interfaces has emerged that represents a baseline of technology needed to implement a fully interoperable, end-to-end spatial data infrastructure. The CITE threads in previous OWS projects have made significant progress towards having a complete suite of compliance tests for this baseline of interfaces.

A major focus of OWS-5 was on achieving consensus on the format and content of an Abstract Test Suite (ATS). The OWS-5 CITE participants agreed to follow the ISO guidance for writing Abstract Test Suites. The ATS are used to develop Executable Test Suites which are the scripts that the TEAM Engine runs to conduct an automated compliance test. A major focus of OWS-6 CITE will be in clearly documenting the approach to defining Abstract Test Suites. This will be a great benefit to the OGC community as the OGC Architecture Board (OAB) requires that new specifications be published with an accompanying ATS. In addition, a focus of OWS-6 CITE will be to expand the usability of the existing OGC compliance tests by "tailoring" these tests for specific schema profiles and/or data.

WCS 1.1.2 Processing extension Request for Comment

Status: 
Please note: This Request is closed. The documents listed below have been adopted by the OGC Technical and Planning Committee. These specifications are under control of the specification Standards Working Group and will be released after the edits and revisions. For the most current version please check our Standards Page.
Description: 
The Open Geospatial Consortium, Inc. (OGC) membership approved a 30 day public comment period for a revision to the OpenGIS® Web Coverage Service (WCS) Interface Standard. The revision includes two extensions to WCS: the WCS 1.1 Transaction Extension and the Web Coverage Processing Service Processing (WCPS) Extension.

The WCS Interface Standard (http://www.opengeospatial.org/standards/wcs) specifies an application programming interface (API) for requesting coverage data, such as imagery, from one or more distributed sources.

The WCS 1.1 Transaction Extension defines how WCS clients can request that a WCS server import one or more new coverages into that server, update existing coverages, and/or delete existing coverages.

The WCPS Extension adds a raster expression language to WCS which allows analysis and processing of multi-dimensional grid coverage data over the World Wide Web. Resulting coverages can be transmitted directly or made available for download by URLs communicated to the client.
