Description: 

 

The Open Geospatial Consortium (OGC) seeks comments on the draft charter of a proposed Interoperable Simulation and Gaming Domain Working Group (DWG).

Gaming systems and technologies, while originally developed for entertainment, are increasingly being used as an interoperable mechanism for simulation of real world activities. Such gaming systems traditionally relied upon fictitious or highly-simplified representations of the world. However, recent years have seen widespread use of realistic depictions of environments and capabilities that can represent large areas of the Earth.

Considerable innovation and enhancements in virtual environment fidelity, as well as reductions in system costs, are expected to result from increased use of cloud, mobile, and immersive technologies. However, most computer-based gaming systems have technical architectures that are different from traditional simulation systems. This DWG will assess how gaming systems might be leveraged for geospatial use cases, including how existing individual vehicle and system operations may be significantly enhanced by interoperation with game-based simulations.

Additionally, the DWG will examine how geospatial data can fit into standard formats and conceptual models compatible with the fast and deterministic storing, retrieval, and rendering of high-quality 3D virtual environments that is required by simulations.

This DWG will provide a forum for the discussion of requirements and use cases for standards and the registration of implementations related to use and re-use of geospatial data within the Interoperable Simulation and Gaming (ISG) community, as well as broader discussion of ISG topics and research activities.

Further, the DWG will aim to increase awareness of the advantages of ISG in general, to define the qualities of ISG systems, to enhance their interoperability, and to support activities to standardize operations within and among them related to the use and re-use of geospatial data

OGC Seeks Public Comment on update to Abstract Specification Topic 2: Referencing By Coordinates

Description: 

 

Third edition of this Abstract Specification describes the requirements for creating coordinate systems referencing locations in space and time.

The Open Geospatial Consortium (OGC) seeks public comment on the third edition of the Abstract Specification Topic 2: Referencing By Coordinates.

Aligned with the draft third edition (2018) of ISO 19111, Geographic Information - Referencing by coordinates, the Abstract Specification describes the data elements, relationships, and associated metadata required for spatial referencing by coordinates, expanded from a strictly spatial context to include time. The document was prepared by the OGC Coordinate Reference Systems Standards Working Group in close collaboration with ISO Technical Committee ISO/TC 211, Geographic information/Geomatics.

In addition to describing a coordinate reference system, the Abstract Specification provides for the description of a coordinate operation between two different coordinate reference systems, or a coordinate operation to account for crustal motion over time. With such information, spatial data referenced to different coordinate reference systems can be referenced to one specified coordinate reference system at one specified time. This facilitates spatial data integration. Alternatively, an audit trail of coordinate manipulations can be maintained.

This third edition cancels and replaces the second edition (OGC Topic 2 of 2008), which has been technically revised. This document also incorporates the provisions of OGC Topic 2.1 of 2010, which is to be cancelled.

The changes in this edition compared to the previous edition are:

  • inclusion of applicable modern geodetic terminology;
  • extension to describe dynamic geodetic reference frames;
  • extension to describe geoid-based vertical coordinate reference systems;
  • extension to allow triaxial ellipsoid for planetary applications;
  • extension to describe three-dimensional projected coordinate reference systems;
  • addition of 'datum ensembles' to allow grouping of related realizations of a reference frame where for lower accuracy applications the differences are insignificant;
  • clarification in the modelling of derived coordinate reference systems;
  • remodelling of the metadata elements scope and extent;
  • addition of requirements to describe coordinate metadata and the relationship between spatial coordinates.
  • additional modelling of temporal coordinate reference system components sufficient for spatio-temporal coordinate referencing;
  • consolidation of the provisions of OGC Abstract Specification Topic 2.1 (Spatial referencing by coordinates - Extension for parametric values) into this document;
  • change in name from 'Spatial referencing by coordinates' to 'Referencing by coordinates', due to the inclusion of the non-spatial coordinate reference system subtypes of parametric (from Abstract Specification topic 2.1) and temporal.
  • the correction of minor errors.

The various OGC Abstract Specifications provide the conceptual foundation for most OGC standards development activities. Open interfaces and protocols are built and referenced against Abstract Specifications, thus enabling interoperability between different brands and different kinds of spatial processing systems. The Abstract Specification provides a reference model for the development of OGC Implementation Standards.

Description: 

OGC seeks public comment on version 1.1 of CDB standard

Minor update to CDB standard brings guidance on metadata, vector network priority, and more.

The Open Geospatial Consortium (OGC) seeks comments on the candidate CDB version 1.1 standard. CDB version 1.1 is a minor revision and is fully backwards compatible with Version 1.0.

The CDB standard defines a conceptual model, as well as rules for implementing the model, for the storage, access, and modification of a synthetic environment data store as required in high-fidelity simulation and mission rehearsal, such as for battlefield simulation. The standard addresses the challenge of full plug-and-play interoperability and reuse of geospatial data in a modeling and simulation environment. CDB data stores can also be exposed by OGC web services, such as a Web Map Service (WMS) or Web Feature Service (WFS) to permit visualization of the content outside of the traditional simulator hardware environment.

The main revisions for this version of the CDB standard are:

  • Detailed guidance on how to implement geospatial metadata in a CDB data store. This guidance is independent from the metadata standard that an organization wishes to use;
  • Incorporation of additional guidance requested by the CDB user community on such topics as vector network priority and significant size;
  • Updates to the CDB schema to add additional lights and feature types as well as spelling corrections and changes to support geospatial metadata;
  • Numerous minor changes to correct ambiguous wording, incorrectly formatted tables, spelling errors and so forth.

​​​​​​​

A detailed description of the changes to the CDB standard can be found in the CDB 1.1 release notes.

OGC seeks public comment on Web Services Security Candidate Standard

Status: 
Please note:  This Request is scheduled to close on 2 April 2018.

Description: 

The Open Geospatial Consortium (OGC) seeks public comment on the OGC Web Services Security Candidate Standard.

For years various implementations of OGC Web Services have integrated some degree of security through Information Assurance (IA) controls . However, these implementations break interoperability, as they each extend the functionality of OGC Web Service (OWS) standards differently. As such, interoperability between secured OGC Web Services and clients is limited to systems custom-built to work with an IA implementation.

The objective of the OGC Web Services Security Standard is to allow the hosting of OWS on HTTPS, the implementation of IA controls and to advertise its existence in an interoperable way with no impact to existing implementations using a backwards-compatible approach. No changes to existing OGC Web Services standards are required. The approach used in this candidate standard is based on existing functionality in the OGC Web Services Capabilities document in a consistent manner.

Uptake of the standardized approach as a build-in to new OGC Web Services standards will ensure security interoperability.

This standard has come as a result of research undertaken during OGC Testbeds 11, 12, and 13, part of OGC’s Innovation Program.

Description: 

The Open Geospatial Consortium (OGC) seeks public comment on the GML in JPEG 2000 (GMLJP2) v2.1 Candidate Encoding Standard.

The GMLJP2 Candidate Encoding Standard defines how the Geography Markup Language (GML) is to be used within JPEG 2000 images and other gridded coverage data for adding geospatial content to imagery, such as the geographic coordinates of the image, annotations, or references to features.

This revised version 2.1 adds support for referenceable grid coverages via a recently published Coverage Implementation Schema (CIS) extension GMLCOVRGRID, which provides additional capabilities for this standard such as support for a wide range of sensor models described with SensorML 2.0 or with GML-based application profiles.

Sensor models envisioned for use with this standard include mathematical descriptions of imaging systems located on satellite and airborne platforms. A full example closely based on the Community Sensor Model for frame cameras is available here.

The standard will appeal to: developers intending to implement geospatially enabled JPEG 2000 encoders and readers; developers of both WFS and WCS who wish to provide support for JPEG 2000 formats; and developers who wish to use GML to give imagery a geospatial context.

OGC seeks public comment on ‘SensorThings API Part 2 – Tasking Core’ Candidate Standard

Status: 
Please note:  This Request is scheduled to close on 22 March 2018.
Open Date: 
Tue, 02/20/2018
Closing Date: 
Thu, 03/22/2018 (All day)
Description: 

The Open Geospatial Consortium (OGC) seeks public comment on the OGC SensorThings API, Part 2 - Tasking Core Candidate Standard. The OGC SensorThings API is a free and non-proprietary lightweight interface specification that simplifies and accelerates the development of Web-based Internet of Things (IoT) applications.

The OGC SensorThings API provides an open, geospatial-enabled, and unified way to interconnect the IoT devices, data, and applications over the Web. Part 1 was released in 2016 and allowed management and reception of observations or measurements made by IoT sensors. Part 2 provides a mechanism to tell the sensor/actuator what to do

Application developers can use this open standard to connect to various IoT devices and create innovative applications without needing to individually integrate the heterogeneous protocols of the different IoT devices, gateways, and services. System manufacturers can embed the OGC SensorThings API in their IoT hardware and software platforms so that the different platforms’ IoT devices can effortlessly connect with other servers that implement the standard. Because device location communication is useful in almost every IoT application, an open, lightweight, widely used standards-based location encoding is part of the SensorThings API.

This new standard is designed specifically for resource-constrained IoT devices and the Web developer community. The candidate standard follows REST principles and uses an efficient MQTT transport and the flexible OASIS OData URL conventions.

The candidate OGC SensorThings API Standard was designed to be compatible with a rich set of proven and widely-adopted open standards, such as the Web protocols and the OGC Sensor Web Enablement (SWE) standards, including the ISO/OGC Observation and Measurement Encoding Standard. Thus, the OGC SensorThings API is extensible and can be applied in both simple and complex use cases.

At a high level, the OGC SensorThings API provides two main functionalities: Sensing, and Tasking. Each function is handled by a part. The Sensing part, an official OGC standard since 2016, provides a standard way to manage and retrieve observations and metadata from heterogeneous IoT sensor systems.

This, the Tasking part, provides a standard way for parameterizing - also called tasking of - task-able IoT devices, such as sensors, actuators, drones, or even satellites.

OGC seeks public comment on Web Coverage Service (WCS) 2.1 Candidate Standard

Description: 

The Open Geospatial Consortium (OGC) seeks public comment on the Web Coverage Service (WCS) 2.1 candidate standard.

The OGC Web Coverage Service (WCS) standards suite defines methodology to access coverages (regular and irregular grids, including spatio-temporal datacubes, point clouds, and general meshes) from the Web. OGC has offered WCS standards since 2005, reflecting the importance and maturity of providing such data to Web clients.

The definition of a coverage is given by the OGC Coverage Implementation Schema (CIS). In 2017, CIS 1.1 was released as a backwards-compatible extension of coverages to CIS 1.0, with a unified grid model supporting any kind of spatio-temporal sensor, image (timeseries), simulation, and/or statistics data.

WCS 2.1 allows CIS 1.1 coverages to be served in addition to CIS 1.0 coverages. Hence, WCS 2.1 is backwards compatible with WCS 2.0: any service passing the WCS 2.1 conformance tests will also pass the WCS 2.0 tests. Further, all WCS 2.0 extensions remain applicable in the context of WCS 2.1.

By supporting the more general datacube model of CIS 1.1, the WCS 2.1 standard will simplify access to spatio-temporal ‘big datacubes’, with an operation spectrum ranging from simple subsetting in space and time up to complex spatio-temporal analytics through Web Coverage Processing Services (WCPS).

Bidders' Q&A Webinar

A Bidders Q&A Webinar was held on Friday, 12 January 2018 at noon US Eastern Standard Time. 

The Webinar recording is available at:  https://portal.opengeospatial.org/files/77559

The Slide deck used for the Webinar is available at:  https://portal.opengeospatial.org/files/77558

Clarification questions and answers will continue to be made available in the CFP Clarifications document at https://proposal.opengeospatial.org/clarification.php.


General Information

The Open Geospatial Consortium (OGC®) has issued a Call for Participation (CFP) in the OGC Testbed 14 Interoperability Testbed.

Testbed 14 sponsors have completed and documented interoperability requirements and objectives for this testbed initiative. Organizations selected to participate in Testbed 14 will develop prototype solutions based on the sponsors’ use cases, requirements and scenarios. These are described in detail in the CFP. Participants’ prototype solutions will implement existing OGC standards as well as new prototype interface and encoding specifications introduced or developed in Testbed 14. Prototype specifications may ultimately become official, member approved OGC standards, revisions to existing OGC standards, or best practices for using OGC standards.

Bidders responding to this CFP must be OGC members and must be familiar with the OGC mission, organization, and process. Proposals from non-members will be considered provided that a completed application for OGC membership (or a letter of intent to become a member) is submitted prior to (or with) the proposal.

The list of Testbed 14 Sponsors can be found on the main Testbed 14 web page: www.opengeospatial.org/projects/initiatives/testbed14

Sponsor requirements have been organized into the following technical threads:

  • CITE: Compliance
  • EOC: Earth Observation & Clouds
  • MoPoQ: Modeling, Portrayal, and Quality of Service
  • NextGen: Next Generation Services

 

Two-Part Solicitation

The Testbed 14 solicitation is being issued in two parts due to specialized sponsor procurement requirements:

  • Part 1 - the CFP document being issued directly by OGC on December 8  and referred to as the "Part 1 CFP" or just "CFP"
  • Part 2 - an Invitation To Tender pack ("Part 2 ITT" or just "ITT"). Please visit the European Space Agency EMITS site for this Invitation to Tender pack. Each solicitation stands on its own, and there is no need to refer to the Part 1 CFP part in order to formulate a response to the Part 2 ITT.

The Part 2 ITT is described separately from this document and has distinct response requirements. So any Bidder wishing to respond to both Part 2 ITT and the Part 1 CFP should deliver two separate proposals, one for each set of response requirements. A Bidder wishing to respond to one or the other (but not both) would submit only one proposal.

The Part 2 ITT was released on 14 December, 2017. To provide a complete description of Testbed-14 scope, this CFP documentation was extended through Corrigenda to combine all deliverables from both parts (Part 1 CFP and Part 2 ITT). All work items marked as belonging to Part 2 ITT have distinct response requirements that are provided as part of the ITT. Bidding on these ITT requirements and work items requires an independent proposal! ITT requirements and work items are only copied into the Part 1 CFP solicitation documents for completeness.

Description: 

 

The Open Geospatial Consortium (OGC) is seeking public comment on its candidate CDB Multi-spectral Imagery Extension standard.

The "Multi-Spectral Imagery" extension defines how to encode and store reflected electromagnetic radiation from the infrared wavelengths into a CDB data store. This extension is limited to only adding this new data type and does not change any existing requirements or structure defined in the CDB standard. This extension also attempts to harmonize with the existing component selectors used in the CDB standard in the visual spectrum.

OGC’s CDB standard defines datasets that represent the visual appearance of objects - from the terrain to buildings and trees - in the electromagnetic spectrum visible to the human eye. CDB also contains material datasets that can help create representations of other wavelengths that can be detected, such as passively emitted heat in the Mid- or Long-Wavelength Infrared (MWIR or LWIR) or reflected Radar (radio wavelengths).

Image sensors that can detect wavelengths between the visible spectrum and Mid-Wavelength Infrared - specifically Near Infrared (NIR) and Short-Wave Infrared (SWIR) - are becoming more prevalent, as is data on these wavelengths. The CDB Multi-spectral Imagery Extension seeks to enable the storage of this data in a CDB data store.
