Description: 

The membership of the Open Geospatial Consortium (OGC®) seeks public comment on the candidate OGC LandInfra Conceptual Model.

This document, the first public draft of the OGC's proposed UML conceptual model for land parcels and the built environment, communicates the proposed intent and content of a new candidate OGC standard to be called the OGC InfraGML Encoding Standard. The UML conceptual model establishes a single set of consistent concepts that could be implemented in GML (as InfraGML) or in other encoding mechanisms.

After reviewing the existing LandXML format, the OGC Land and Infrastructure Domain Working Group (LandInfraDWG) decided that a fresh start standard was warranted. The new standard would have a use case driven subset of LandXML functionality, but it would be consistent with the OGC standards baseline, implemented with the OGC Geography Markup Language (GML), and supported by a Unified Model Language (UML) conceptual model. Called InfraGML, this new standard would: be supported by a recognized Standards Developing Organization, OGC align with existing OGC (and TC211 and SQL/MM) standards, including the OGC Modular Specification benefit from functionality already supported by GML, including features, geometry, coordinate reference systems, linear referencing, and surface modeling (TIN) initially focus on alignments/roads, survey, and land parcels, the subject areas for which there are identified needs and committed resources for development using modular extensions, be able to expand into other areas (e.g., "wet" infrastructure pipe networks) as resources become available be use-case driven be based on a UML conceptual model developed prior to any encoding, such as GML have more up-to-date functionality be synchronized with the concurrent efforts by buildingSMART International in their development of Infrastructure-based Industry Foundation Classes (IFCs), and be more easily integrated with TransXML and OGC CityGML.

The document for the candidate OGC LandInfra Conceptual Model are available for review and comment below.  Comments are due by 22 February, 2015.

Description: 

The membership of the Open Geospatial Consortium (OGC®) seeks public comment on the candidate OGC KML 2.3 Standard.

KML is an XML grammar used to encode representations of places and objects for display in an earth browser, such as a 3D virtual globe, 2D web browser application, or 2D mobile application. KML can be used to accomplish various map and Earth image functions, such as: annotate places, specify icons and labels to identify geographic locations, create different camera positions to define unique views for KML features, define image overlays to attach to map views, and define the location and orientation of textured 3D objects.

The main KML enhancements provided in version 2.3 are:

  1. Addition of a new feature, KML Tour, which enables a user to specify aspects of a controlled virtual flight through a series of geographic locations, including speed, mode of flight (smooth or bounce), sound tracks and how KML features are updated throughout the tour.

  2. Addition of new geometries: Track and MultiTrack. A KML Track can capture and display the path and other aspects of  a moving object over a specified period of time.

  3. Enhancements to KML’s Extension Mechanism, allowing for the direct use of XML content from third-party schemas. KML 2.3 is now based on XML Schema 1.1 enabling Aauthors of KML Application Profile extensions are now able to experimentally add foreign element and attribute content interleaved among existing KML elements.

The documents for the candidate OGC KML 2.3 Standard are available for review and comment below.  Comments are due by 18 January, 2015.

OGC seeks public comment on the Earth Observation Metadata profile of the OGC Observations & Measurements Standard

Status: 
Please note:  This Request is scheduled to close on 17 December 2014.

Description: 

The membership of the Open Geospatial Consortium (OGC®) seeks public comment on the candidate Earth Observation Metadata Profile of the OGC Observations and Measurements (O&M) Standard.

The Earth Observation (EO) Metadata profile of Observations and Measurements is intended to provide a standard schema for encoding Earth Observation product metadata to support the description and cataloguing of products acquired by sensors aboard EO satellites.

EO products are differentiated by parameters such as the date of acquisition and the image footprint as well as characteristics pertaining to the type of sensor, the type of platform, the applied processing chain, and more. This candidate standard identifies the metadata elements that enable the robust description of general EO products and defines specialisations for specific thematic classes of EO products, such as optical, radar, atmospheric, altimetry, limb-looking and systematic/synthesized EO products. In addition, this document describes the mechanism used to extend these thematic schemas for specific EO missions.

Version 1.0 of the EO Metadata profile of O&M is an OGC Implementation Standard that was adopted in 2012. Since then the standard has been implemented by the EO ground segments of a number of EO missions. During these implementations, a number of improvements and corrections have been identified. The proposed version 1.1 addresses these corrections and improvements.

The documents for the candidate OGC Earth Observation Metadata profile of Observations & Measurements Standard are available below for review and comment.

Description: 

The Open Geospatial Consortium (OGC®) has issued a Request for Quotation/Call for Participation (RFQ/CFP) in the OGC Testbed 11 Interoperability Testbed.

Testbed 11 sponsors have documented interoperability requirements and objectives for this testbed activity. Organizations selected to participate in Testbed 11 will develop solutions based on the sponsors’ use cases, requirements and scenarios, which are described in detail in the RFQ/CFP. Participants’ solutions will implement existing OGC standards as well as new prototype interface and encoding specifications introduced or developed in Testbed 11. Prototype specifications may ultimately become OGC standards, revisions to existing OGC standards, or best practices for using OGC standards.

Testbed 11 Sponsors include:

  • European Organization for the Safety of Air Navigation (EUROCONTROL)
  • Land Information New Zealand (LINZ)
  • National Aeronautics and Space Administration (NASA)
  • National Geospatial-Intelligence Agency (NGA)
  • UAE Ministry of Interior Abu Dhabi Police GIS Center for Security (UAE - ADP GIS CS)
  • UK Defense Science and Technology Lab (UK-DSTL)
  • US Department of Homeland Security (DHS)
  • US Geological Survey (USGS)

The RFQ/CFP and information about Testbed 11 are available below. Responses are due by 5:00 pm EST on 21 November 2014.

An IP Program and Testbed 11 Q&A Webinar will be held on 30 October 2014 at 10 am EDT ( Check your local time ). Register here: https://www4.gotomeeting.com/register/287254487.

For the most efficient use of this webinar, please send your questions in advance to techdesk [at] opengeospatial.org. You are also invited to follow us on twitter, Linkedin or Facebook to stay updated on the Q&A Webinar, clarifications to requirements, kickoff details, etc.

The OGC Testbed 11 Kickoff Workshop is planned for 12-14 January 2015 at George Mason University (GMU), Fairfax Campus in Northern Virginia. Additional details for the Kickoff Workshop will be provided later.

Testbed 11 focuses on spatial communication requirements that emerge when a population is displaced due to coastal inundation. Testbed participants addressing requirements in this scenario will attempt to meet these goals:

  • Advance OGC Architecture with respect to REST and SOAP design patterns for synchronization of geodata across data stores, as well as storage and synchronization of geodata in GeoPackages;
  • Evaluate approaches to JSON and GeoJSON encodings as well as vector data and image streaming in the OGC standards framework;
  • Integration of high-resolution simulation models into geospatial infrastructures
  • Advance use of Linked Data and Semantic Enabling of OGC Web Services, with a special focus on Hydrographic Data;
  • Advance use of OGC Catalog Services;
  • Advance use of spatially enabled Social Media data;
  • Advance use of a common symbology that can be used to share common operational pictures in an international environment;
  • Advance compliance tests for the OGC Web Feature Service and Catalog 3.0 Service interface standards;
  • In Aviation, advance a Digital NOTAM validation service and enrichment service and advance use of Aviation Feature Schema (AFX). Also develop guidance on using geometrical constraints in the Semantics of Business Vocabulary and Rules (SBVR) (an Object Management Group standard).

Those testbed goals sort into these technology threads:

  • Cross-Community Interoperability (CCI) Thread
  • Urban-Climate Resilience (UCR) Thread
  • Geospatial Enhancements for NIEM (Geo4NIEM)

This cutting edge technology work has enormous potential for testbed stakeholders – both the technology users and the technology providers – and for the world at large. The return on the shared investment in spatial standards is extraordinary, much like the return on the original shared investments in http and html. Technology providers gain market exposure, market intelligence, and a chance to quickly take advantage of the business opportunities that arise with the introduction of new standards and associated technical capabilities.

If you want to learn more about this opportunity, please contact  Lew Leinenweber , Director Interoperability Programs (techdesk [at] opengeospatial.org). See http://www.opengeospatial.org/ogc/programs/ip for more information about the 15 year old OGC Interoperability Program in which OGC testbeds, pilot projects and interoperability experiments are organized, planned and managed.

Description: 

The Open Geospatial Consortium (OGC®) membership seeks public comment on the candidate OGC Web Processing Service (WPS) Version 2.0 Interface Standard.

In many cases geospatial or location data, including data from sensors, must be processed before the information can be used effectively. The OGC Web Processing Service (WPS) Interface Standard provides a standard interface that simplifies the task of making simple or complex computational processing services accessible via web services. Such services include well-known processes found in spatial extract, transform, and load (ETL) software and GIS software as well as specialized processes such as coordinate transformation and spatial and temporal modeling and simulation. Moreover, the WPS standard supports both immediate processing for computational  tasks that take little time and asynchronous processing for more complex and time consuming tasks. While the OGC WPS standard was designed with spatial processing in mind, it can also be used to readily insert non-spatial processing tasks into a web services environment.

This WPS 2.0 candidate standard is a revision of WPS 1.0 (published in 2007). It incorporates change requests that have been submitted since the release of WPS 1.0 and provides improved support for process cataloguing and retrieval.

The 30 day public comment period for the candidate OGC Web Processing Service (WPS) Version 2.0 Interface Standard ends 25 September 2014 [ extended until 9 October 2014 ]. After the OGC’s WPS Standards Working Group has addressed comments received in response to this Request for Comments (RFC) the draft document will be submitted to the OGC Technical Committee and Planning Committee for their review and possible approval as an adopted OGC Standard.

The WPS 2.0 candidate standard doscument can be downloaded below:

OGC calls for comment on candidate Moving Feature Encoding standard

Status: 
Please note:  This Request is scheduled to close on 23 August 2014.
Open Date:

Closing Date:

Description: 

The OGC seeks public comment on a candidate OGC® Moving Feature Encoding Standard. Part I of this candidate standard provides a standard way of encoding moving feature data in an XML encoding in the form of an OGC Geography Markup Language (GML) application schema. Part II provides a standard way of encoding moving feature data in a simple CSV (comma-separated value) format.

The candidate OGC® Moving Feature Encoding Standard is available below. Comments are due by 23 August 2014.

The advance of mobile computing and internet-connected sensors (including sensors and GPS transponders in cell phones and notebook computers) brings with it a rapid rise in applications for moving feature data, typically representing vehicles or pedestrians. Many innovative moving feature applications will require the overlay and integration of moving feature data from different sources. Examples can easily be imagined for disaster risk management, traffic information services, security services, navigation for robots, aviation or maritime traffic monitoring, and wildlife tracking and conservation. Most current applications, however, are limited to single-source moving feature data.

More efficient moving feature data exchange will result in a requirement for massive data handling. The CSV style encoding provides an efficient and easily understood standard for encoding lightweight data records, which will be important for many applications involving large data volumes and real-time response. The GML application schema style encoding for Moving Features provides for the encoding of more complex spatial information.

This standard addresses only “rigid” moving features, such as vehicles, as opposed to those that deform, such as flood water, and it does not address moving features whose descriptions contain other moving features that must be updated as the feature moves, such as control surfaces on an unmanned aerial vehicle (UAV). It also is for archived Moving Feature data only, and not for live feeds from sensors.

Description: 

The Open Geospatial Consortium (OGC®) membership seeks public comment on the candidate OGC GML Application Schema - Coverages – JPEG2000 Coverage Encoding Extension (abbreviated as “GMLCOV for JPEG2000”).

GIS coverages (including the special case of Earth images) are two- (and sometimes higher-) dimensional metaphors for phenomena found on or near a portion of the Earth's surface. Coverage instances may be encoded using the OGC GML Application Schema – Coverages (GMLCOV) Encoding Standard, which is based on the Geography Markup Language (GML), an XML grammar written in XML Schema for the transport and storage of geographic information. GMLCOV for JPEG2000 specifies an encoding of GML coverages for the JPEG2000 data exchange formats for still imagery (i.e. JPC, JP2, JPX). This document is the basis for the GML in JPEG2000 encoding standard v2.0 and a future format extension for WCS.

This candidate standard can be downloaded below.

Suggested additions, changes, and comments on this candidate standard are welcomed and encouraged. Such suggestions may be submitted by 20 August 2014.

Description: 

The Open Geospatial Consortium (OGC™) membership seeks public comment on the candidate OGC Web Map Tile Service Simple Profile of the OGC Web Map Tile Service (WMTS) Interface Standard.

Current OGC WMTS Interface Standard implementations return small, pre-generated map images (e.g., PNG or JPEG) or reuse cached map requests that follow a discrete set of tile matrices. The standard defines rules for multiple request/response patterns, including KVP, REST and SOAP.

The candidate OGC WMTS Simple Profile aligns the currently implemented and more comprehensive OGC WMTS Interface Standard to other popular tile initiatives that are less flexible but widely adopted. Server implementations of this profile should share two common sets of tile matrices and have a mandatory RESTful interface, though other interfaces are allowed. The WMTS Simple Profile is designed to allow developers to more quickly implement the WMTS standard.

Description: 

The Open Geospatial Consortium (OGC®) Membership seeks public comment on a new version of the OGC Catalogue Service interface standard. This standard specifies a design pattern for defining interfaces to publish and search collections of descriptive information (metadata) about geospatial data, services and related information objects.

There are three documents being considered. The first document defines the General Model for a catalogue service. The General Model is technology neutral. Therefore, the second document describes the rules for deploying a Catalogue Service in the HTTP environment, also known as Catalogue Service for the Web, or CS-W. The third document contains a detailed Abstract Test Suite for conformance classes described in the CS-W document. The main changes from version 2.0.2 include the migration to a fully stateless model, removal/deprecation of the Z39.50 and CORBA bindings, inclusion of OpenSearch compatibility, and support for the OGC modular specification approach for specifying requirements and conformance classes.

The new version of the candidate OGC Catalogue Service interface standard is available for comment below:
