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.

OGC Seeks Comments on Ordering Service Candidate Standard

Status: 
Please note: This Request is scheduled to close on 23 February 2011.
Description: 

The Open Geospatial Consortium (OGC®) seeks public comment on the candidate OGC Ordering Services for Earth Observation Products Interface Standard. This candidate interface standard defines interfaces for ordering products derived from Earth observation satellites. In particular it provides interfaces for:

Getting the processing and delivery options available for specific Earth observation products

Getting the price quotation for an order to be submitted

Submitting the order

Monitoring the status of the submitted orders and optionally cancelling them

Retrieving the products (on-line, if supported by the server)

 

 

This candidate standard has been prepared by the OGC Technical Committee Ordering Standards Working Group and it is based on an existing specification prepared and implemented in several ESA (European Space Agency) projects. Currently, implementations are available from at least the following space agencies:

• ESA

• Eumetsat

• DLR

Other implementations are being developed, including those being developed in GMES-related activities.

 

This candidate standard is designed to work with the OGC Sensor Web Enablement (SWE) suite of standards: For the modelling of ordering options the SWE Common specification has been selected and some elements are shared with the OGC Sensor Planning Service Interface Standard (SPS).

 

The candidate OGC Ordering Services for Earth Observation Products Interface Standard can be found below. The period for issuing comments expires on 23 February 2011.

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.

OGC Requests: 

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

OGC Calls for Comment on Table Joining Service Standard

Status: 
Please note: This Request is scheduled to close on 14 April 2010.
Description: 

The Open Geospatial Consortium, Inc. (OGC®) seeks public comment on the draft OGC Table Joining Service (TJS) Interface Standard. This standard defines an interface for services that provide the ability to join attribute data stored in one database on a network with the corresponding geometry (points, lines, or polygons) stored in another network accessible database.

 

For example, a table on one server may indicate the population of various cities, while a second server may contain the geometry that describes the cities' locations and boundaries. The TJS standard describes a set of interfaces for both servers that would allow the city name to be used as the "common geographic identifier" in order to join the population data to its geometry, thus enabling the user to create a map or perform geospatial analysis on the tabular data. An earlier draft of this specification was called the “Geographic Linkage Service”.

 

The proposed OGC TJS 1.0 standard and information on submitting comments on this document are available below.  The public comment period closes on 14 April, 2010.

The OGC seeks comment on SensorML 2.0 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 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 the candidate OGC SensorML 2.0 Encoding Standard.

SensorML is a machine-readable language for describing sensors, actuators, and processes surrounding measurement. SensorML is a key component of the OGC Sensor Web Enablement (SWE) suite of standards.

SensorML 2.0 includes the following changes to the previous version 1.0.1, which was approved in 2007:

  •  Separation of SWE Common Data as a separate standard
  •  More tightly defined rules
  •  Conformance classes allowing for incremental support of SensorML in software and derived encodings
  •  A host of examples provided at initial release of the specification.

 

In addition, SensorML 2.0 includes the following new or improved features:

  •  Support for property extension using external schema
  •  Better-defined support for positions and dynamic state (e.g. location, orientation, velocity, and acceleration)
  •  Better support for inheritance allowing for compact descriptions of deployed devices and processes
  •  Direct access to real-time values and data streams
  •  Better support for multiplexed data streaming (i.e. streams with disparate messages).

SensorML 2.0 supports the descriptions of things within the Internet of Things (IoT) and Web of Things (WoT) by providing a common standard for sensors ("things the measure"), actuators ("things that act"), and processors ("things that calculate"). Efforts are also underway to take advantage of the complementary role that SensorML 2.0 can play with the OGC City Geography Markup Language (CityGML) Encoding Standard and the candidate OGC standard IndoorGML.

The OGC SensorML 2.0 Encoding Standard Evaluation Package is free and can be downloaded below.

This document describes TML and how it captures necessary information to both understand and process transducer data. Descriptions of how TML captures the actual data and also descriptions of necessary information such as system calibration, transducer behavior, conditions of operation and data collection parameters critical to logical data structure model are all captured within TML. This document specifically describes the TML transducer behavior models and TML data models. It does not describe a service for delivering TML-structured data, but there is a brief discussion of SOA and streaming platform considerations.
