Description: 

The Open Geospatial Consortium (OGC®) seeks comment on the candidate GML in JPEG 2000 Encoding Standard version 2. This geospatial data encoding standard defines how the Geography Markup Language (GML) is to be used within JPEG 2000 images for adding geographic content to imagery. Once approved, the revised GML in JPEG2000 version 2 candidate standard joins a suite of international open standards that provide a platform for seamless service-based publishing, discovery, assessment, ordering, access and processing of geospatial information.

Version 1.0.0 of this standard was published in January of 2006. The new candidate version 2 of the standard exploits the capabilities of the OGC GML Coverage Application Schema (GMLCOV) and the OGC Web Coverage Service (WCS) 2.0 Interface Standard that have been made available by the OGC since 2006. Version 2 eliminates other shortcomings of Version 1 and also addresses shortcomings of competing methods of using JPEG2000 in geospatial applications.

All OGC standards are free and publicly available on the OGC Standards Page. The candidate GML in JPEG 2000 Encoding Standard version 2 can be downloaded below.

The GML in JPEG 2000 Standards Working Group (GMLJP2 SWG) will consider comments on the candidate GMLJP2 Standard that have been posted through 19 March 2014

Description: 

The Open Geospatial Consortium (OGC®) is seeking comments on the candidate standard, "OGC® OpenSearch Geo and Time Extensions". This document extends the implementation of the popular OpenSearch technologies so that users can take advantage of the geospatial search capabilities enabled by OGC standards. 

Different types of content require different types of search engines. OpenSearch (http://www.opensearch.org) provides a standard way of describing search engine capabilities so that they can be leveraged by search client applications like modern Web browsers. The OGC® OpenSearch Geo and Time Extensions candidate standard provides a very simple way to configure OpenSearch for spatial and temporal queries over distributed repositories of contents having geographic and time properties, and for syndication of these search results in one large index.

Digital resources are becoming more complex and diverse, and this is especially true with respect to sensor data and Web connected sensors. Such data is increasingly becoming discoverable and usable through open interfaces that implement OGC standards (http://www.opengeospatial.org/standards), but most of this data remains undiscoverable via popular search engines. The OGC OpenSearch Geo and Time Extensions candidate standard specifies how to enhance search engines and configure them to access sensor data servers, so that users can query resource URLs through search combinations of time extents, geographic areas or location names, and likely keywords. 

The OGC® OpenSearch Geo and Time Extensions draft standard includes work undertaken within the GENESI-DR (Ground European Network for Earth Science Interoperations - Digital Repositories) project funded by the 7th Framework program of the European (EC Grant Agreement no. 212073) and the follow-up project GENESI-DEC (Ground European Network for Earth Science Interoperations - Digital Earth Community) funded by the same program (Contract nº RI-261623). The document was further supported by the ESA HMA (Heterogeneous Missions Accessibility) initiative and related projects.

OGC Calls for Participation in ECO9 OGC Pilot

Status: 
Please note: January 9, 2009 - The Open Geospatial Consortium is withdrawing the EC09 Pilot RFP-Q that was issued 22 December, 2008, due to lack of funding.

THERE IS ONE CLARIFICATION FOR THIS CALL (see below).
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 09 Pilot (EC09 OGC Pilot).

The EC09 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 for the pilot network. Responses are due by January 14, 2009 and the Pilot Kickoff Meeting will be held the week of 10-11 February 2009, in the Washington, DC area. Technology deployments will be complete by July 17, 2009, followed by a two-week demonstration phase for the remainder of July.

The EC09 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.

The OGC seeks comment on City Geography Markup Language (CityGML) V1.1

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 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 (OGC®) seeks public comment on Version 1.1 of the OGC City Geography Markup Language (CityGML) Encoding Standard (http://www.opengeospatial.org/standards/citygml).

CityGML is an open information model and XML-based encoding for the representation, storage, and exchange of virtual 3D city models. It provides a way to describe objects with respect to their geometry, topology, semantics and appearance, and it defines five different levels of detail. CityGML allows users to employ virtual 3D city models for sophisticated analysis and display tasks in different application domains such as pedestrian navigation, environmental simulations, urban data mining, facilities management, real estate appraisal, and location based marketing.

CityGML has been implemented in many software solutions and is in use in many projects around the world. Developed for Urban Information Modeling applications, CityGML plays an important role in bridging Urban Information Models with Building Information Models (BIM) to improve interoperability among the information systems used in the many areas of activity that involve design, construction, ownership and operation of buildings and capital projects.

CityGML is implemented as an application schema of the OGC Geography Markup Language 3 (GML3) Encoding Standard (http://www.opengeospatial.org/standards/gml), an international standard for spatial data exchange and encoding approved by the OGC and the International Organization for Standardization (ISO).

The current version 1.0 of CityGML was adopted as an official OGC Standard in August 2008 and has come to wide use since then. The OGC Technical Committee's CityGML Working Group has received input from the wider community in the form of change requests, proposed additions and suggestions. With this guidance, the Working Group developed the draft CityGML Version 1.1, a minor revision of the current CityGML version 1.0 that maintains backwards compatibility with version 1.0. Version 1.1 includes new thematic modules for tunnels and bridges, the ability to model footprint and roof edge representations for buildings in the coarsest level of detail, and generic attribute sets, as well as a number of additional properties and other enhancements.

 The candidate CityGML Version 1.1 standard documents are available for review and comment below. Comments are due by 14 September 2011.

OWS-5 Testbed Addendum Released

Status: 
Please note: This Request is closed.
Description: 
RFQ Issuance Date: 7 September, 2007
Clarifications Posted: 17 September, 2007
Proposal Due Date: 5 October, 2007

 


Overview

This document is an addendum to the previously issued OWS-5 RFQ/CFP and includes new requirements to be included in the Agile Geography thread of the ongoing OWS-5 testbed. The requirements within this addendum should be addressed within the overall context of the original OWS-5 RFQ/CFP. It should be noted that schedule information contained within this document supercedes that which was found in the original OWS-5 RFQ/CFP.

The content within this RFQ covers two topics and are described in further detail below:

  1. GeoSynchronization
  2. OWS Core and Extension Experiment

1) GeoSynchronization

GeoSynchronization targets a federated environment comprised of loosely affiliated parties who desire to collaborate on the development and maintenance of a shared geospatial data set. Additionally, technology is enabling new online markets for information sharing and processing to emerge. These too can achieve cost and time benefits from leveraging loosely coupled, industry standards for sharing and synchronization. Solving this interoperability issue is of critical importance to ongoing Spatial Data Infrastructure (SDI) initiatives across the globe, as parties with differing software infrastructures, organizational goals, and legal mandates seek to increase the availability of geospatial information across society without incurring prohibitive costs. While existing OGC technologies have made it easier to publish information in an interoperable manner, creating the potential for effective sharing and collaboration, another level of interoperability technology is required to manage the intricacies of cross-organizational data sharing, which may include acceptance, validation, rejection, and description of operations on information streams.

In this testbed participants will be funded to experiment with solutions that leverage GML-based information models, such as the GML profiles being developed for US framework data sets and the Canadian Geospatial Data Infrastructure. Mass market information models, such as Atom+GeoRSS GML and KML may be considered as well. It is expected that investigations in this area will likely extend the WFS Transactional architecture to accommodate a more loosely coupled approach. However, alternative architectures will be considered as well.

 

2) OWS Core and Extension Experiment

The OGC in general, and the OGC Architecture Board (OAB) in particular, is considering a more formal, modular approach to standards that is described in "OGC Abstract Specification - The Model Specification - Structuring an OGC specification to encourage implementation, version 07-056r2". In support of this effort, this OWS-5 task uses the guidance from this document and applies it to the "OpenGIS® Web Feature Service (WFS) Implementation Specification", "Gazetteer Service - Application Profile of the Web Feature Service Implementation Specification", and the Web Processing Service.

The OGC requests comment on the Interpolation Extension to the OGC Web Coverage Service Interface Standard

Status: 
Please note: This call is now closed.
Closing Date: 
Sun, 09/22/2013 - 04:00
Description: 

The Open Geospatial Consortium (OGC®) is seeking comments on the candidate OGC Web Coverage Service (WCS) Interface Standard Interpolation Extension.

The OGC Web Coverage Service (WCS) Interface Standard defines an open standard interface to access multi-dimensional spatio-temporal coverages, such as sensor data, satellite imagery, image time series, point clouds, and meshes. The candidate WCS Interpolation Extension document specifies parameters to the WCS GetCoverage request that provide control over interpolation of a coverage during its server-side processing. WCS has a core mission to preserve data quality, and by default always delivers original, unaltered data. Whenever interpolation – which may impact accuracy – is necessary, this extension allows clients to specify the interpolation method that the server shall apply. This can even be indicated individually per axis, such as “perform linear interpolation along latitude and longitude, but perform nearest-neighbor interpolation along time.”

An overview of the complete WCS suite is available at http://external.opengeospatial.org/twiki_public/CoveragesDWG/CoveragesBigPicture.

All OGC standards are free and publicly available. Download the candidate OGC WCS Interface Standard Interpolation Extension below. Comments are due by 22 September, 2013.

OGC Seeks Comments on Candidate XML Standard for Encoding Observations & Measurements

Status: 
Please note: This Request is scheduled to close on August 7th, 2010.
Description: 

The Open Geospatial Consortium, Inc. (OGC®) Members are seeking comments on the “Observations and Measurements – XML Implementation” candidate standard. This candidate standard specifies an XML encoding for the Observations and Measurements conceptual model.

 The Observations and Measurements (O&M) conceptual model, a joint OGC and ISO standard, provides the theoretical basis for an abstract model encoding for observations and provides support for common sampling strategies. O&M also provides a general framework for systems that deal in technical measurements in science and engineering.

 The candidate OMXML standard and other standards that have resulted from the OGC's Sensor Web Enablement (SWE) effort (http://www.opengeospatial.org/ogc/markets-technologies/swe) enable developers to make all types of sensors, transducers and sensor data repositories discoverable, accessible and useable via the Web.

 The candidate OGC Observations and Measurements – XML Implementation Encoding Standard and information on submitting comments on this document are available at http://www.opengeospatial.org/standards/requests/68. The public comment period closes on August 7th, 2010.

The OGC calls for comments on the Open Modelling Interface (OpenMI) standard

Status: 
Please note: This Request closed on 1 June 2013.
Closing Date: 
Sat, 06/01/2013 - 04:00
Description: 

The Open Geospatial Consortium (OGC®) and the OpenMI Association (OA) have announced a call for public comment on the Open Modelling Interface Version 2 (OpenMI) and its accompanying reference manual. This standard defines a means by which independently developed computer models of environmental processes, or indeed any processes, can exchange data as they run and hence facilitates the modelling of interacting processes.

The original driver for the standard was the European Water Framework Directive and its requirement for an integrated approach to water management. It was foreseen that implementing the Directive would be very challenging and that there would be a need to provide help, in the form of decision support systems (DSS), to environmental managers. As Earth systems are complex and interrelated, these DSS would need to bring together many models in order to better understand and predict the environmental impacts of events and policies. To make it feasible to link together models of different processes from different suppliers and hence simulate process interaction, the European Commission therefore co-funded the research and development of a generic model interface, the outcome of which is the OpenMI.

Roger Moore, chairman of the OpenMI Association, said, “The OpenMI Association sees huge opportunities ahead for many stakeholder groups if the linking of models of different processes as they run can be made simple and reliable. Our immediate goal is to facilitate the integrated modelling needed to understand Earth system processes and hence help scientists, policy makers and managers find sustainable solutions to environmental challenges. By publishing the OpenMI as an adopted OGC standard, we seek to make the OpenMI standard available and accessible to the worldwide modelling community.”

Environmental modelling is not the only application of integrated modelling. For example, a possible shorter term application will simply be in enabling developers to convert their existing large, and often unmanageable, applications into sets of linkable components. This could change the modelling market from one for complete systems into one for components and services. It could make it much easier for products to be brought to market, widen participation and dramatically drive up the rate of innovation.

The documents being released for comment have been specially prepared so that the description of the OpenMI matches the OGC style. They can be viewed and downloaded
