02 July 2015. Members of the Open Geospatial Consortium (OGC®) request comments on the OGC® Web Coverage Service 2.0 Interface Standard – JPEG2000/JPIP Coverage Encoding Extension – abbreviated as “JPEG2000/JPIP-Coverage”. This candidate OGC Best Practice extends version 2.0 of the OGC Web Coverage Service (WCS) Interface Standard to add support for requesting and returning coverage data formatted as JPEG 2000 (JP2), both as a static image and as a JPEG 2000 Interactive Protocol (JPIP) stream, encoded using either the classic JP2 format or the OGC GML in JPEG 2000 Encoding Standard.

The OGC WCS Standard provides an interface for requesting and returning various types of geospatial coverage information, such as satellite images, regular and irregular geospatial grids, point clouds, and meshes. JPEG 2000 (an ISO/IEC standard) is an image compression standard and coding system. JPIP, also an ISO/IEC standard, is a compression streamlining protocol that works with JPEG 2000 to produce an image using as little bandwidth as necessary. JPIP enables downloading of only the requested part of a picture, saving bandwidth, computer processing on client and server, and time. JPIP allows for the relatively quick viewing of a large image in low resolution, as well as a higher resolution part of the same image.

JPEG2000/JPIP-Coverages details can be found in the candidate OGC Best Practice  document titled OGC® Web Coverage Service 2.0 Interface Standard – JPEG2000/JPIP Coverage Encoding Extension.

This OGC candidate standard is available for review and comment at http://www.opengeospatial.org/standards/requests/136.

25 June 2015. The OGC membership seeks public comment on the candidate OGC® Web Coverage Service (WCS) - Transaction operation extension, version 2.0.

The OGC Web Coverage Service (WCS) Interface Standard is an open standard widely implemented in geospatial applications around the world. The standard’s main function up until now has been to support retrieval of geospatial "coverages" data such as spatio-temporal sensor, image, simulation, and statistics data. With the new Transaction extension, the standard will support not only retrieval but also transactions such as create, update, and delete. When geographic information systems (GIS), scientific models and other geospatial systems and services implement the standard, users of those systems and services gain versatile access to geospatial information from a wide variety of sources. Such access will be useful generally in geospatial information management and use, and also in “big data” applications that involve geospatial data.

This OGC candidate standard is available for review and comment at http://www.opengeospatial.org/standards/requests/135.

29 June 2015. The Open Geospatial Consortium (OGC) membership has approved the OGC Web Processing Service (WPS) Version 2 Interface Standard.

The OGC Web Processing Service (WPS) Version 2 Interface Standard provides rules for standardizing how inputs and outputs (requests and responses) for geospatial processing services, such as polygon overlay, can be structured in a standard way. WPS also defines how a client can request the execution of a process, and how the output from the process is handled. By implementing this standard, any geospatial processing service, regardless of the source, can be “wrapped” with a standard interface and integrated into existing workflows. WPS supports both immediate processing for computational tasks that take little time and asynchronous processing for more complex and time consuming tasks. Moreover, the WPS standard defines a general process model that is designed to provide an interoperable description of processing functions. It is intended to support process cataloguing and discovery in a distributed environment.

This standard is a continuation of WPS 1.0. It incorporates a range of change requests that have been submitted since the release of WPS 1.0 and further conforms to the OGC standard for modular specifications (OGC 08-131r3). In contrast to Version 1.0, WPS 2.0 provides a core conceptual model that may be used to specify a WPS in different architectures such as REST or SOAP.

The WPS process model has been encapsulated into separate requirements and conformance classes so it may be used independently from WPS servers in process catalogs and metadata records. The expressive power of process descriptions has been enhanced by permitting structured (or nested) inputs and outputs. The concept of process profiles has been clarified and extended to support process descriptions at different levels of abstraction.

Conversely, the process model itself has been largely decoupled from the WPS protocol, allowing the use of other domain-specific descriptions of processes, e.g. those defined in OGC SensorML, and to execute them on a WPS server.  WPS 2.0 also provides a Basic WPS conformance class that comprises the synchronous and asynchronous execution protocol.

23 June 2015. Members of the Open Geospatial Consortium (OGC®) request comments on the draft charter for an OGC Hydrologic Features (HY_Features) Standards Working Group (SWG). The purpose of the proposed SWG is to progress the HY_Features hydrologic feature model to the state of an adopted OGC standard for a common and stable identification and referencing of hydrologic features.

Water information needs to be shared between many organisations. HY_Features in conjunction with the OGC WaterML2. standard provides a baseline for improving the way in which water information is organized, managed and shared.

Hydrologic features are the “unit of study” for water information, and a means is required to convey identity of such real-world water-objects through the data processing chain from observation to water information. The work undertaken in the OGC Hydrology DWG led to a series of water-related standards and best practices to manage at different levels of detail the identification, observation and representation of hydrologic features. Examples are the WaterML2.0 standard, the HY_Features common hydrologic feature model and the ongoing GroundWaterML2 work. Each standard is concerned with different aspects of hydrology and water information. In conjunction these standards support a common understanding of the Hydrology phenomenon, which provides the basis of linking application-specific concepts by referencing common semantics. This allows informations systems and Web services as well as domain-specific ontologies (such as the terms using in existing data products) to be linked using a common reference model.

The Hydrologic Feature standard will be split into 3 parts. This approach allows conceptual issues to be addressed separate from physical implementation.

  • Part 1: A HY_Features conceptual model (OGC 14-111). The normative model is a machine-readable Unified Modeling Language (UML) artefact published by the OGC.
  • Part 2: A GML implementation schema suitable for data transfer of HY_Features object instances, based on ISO 19136 Annex E encoding rules for Application Schema.
  • Part 3: OWL and RDF representation suitable for defining links between features that implement the HY_Features model, to based on ISO 19150 encoding rules (when these become an accepted standard).

The draft charter is available for review at https://portal.opengeospatial.org/files/64089. Comments should be sent via email to charter-requests [at] opengeospatial [dot] org and are due by 23 July, 2015.

18 June 2015. The OGC® membership seeks public comment on the candidate OGC SensorThings API Standard, Part 1. 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.

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 JSON encoding 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 a Sensing Profile and a Tasking Profile. The Sensing Profile, which is Part 1, provides a standard way to manage and retrieve observations and metadata from heterogeneous IoT sensor systems, similar to the OGC Sensor Observation Service (SOS) Interface Standard. The Tasking Profile, when completed as SensorThings Part 2, will provide functions similar to the OGC Sensor Planning Service (SPS) Interface Standard.

The SensorThings API RFC can be downloaded from http://www.opengeospatial.org/standards/requests/134. Comments are due by 18 July 2015.

18 June 2015. Members of the Open Geospatial Consortium (OGC®) request comments on the draft charter for an OGC Point Cloud Domain Working Group (DWG).  

The Point Cloud DWG is being established to address the gap in the OGC standards baseline with regard to interoperability issues related to sharing and processing point cloud data. The group will not create new standards but will provide a collaborative discussion forum to define and understand issues, requirements, use cases or barriers to interoperability that are of concern to the point cloud community.

The planned new DWG represents an acknowledgment of the gap in the current OGC baseline regarding standardization of point cloud data and service formats. This working group is motivated by the fast growing popularity and use of point cloud technology and data. This includes a number of formats and types such as: laser scans from aerial and terrestrial platforms (e.g., LiDAR), triangulated elevation points, dense observations from the meteorological community, and others.  Based on these considerations this charter defines the OGC Point Cloud Domain Working Group (DWG).

The OGC has a number of Working Groups in which members discuss issues relating to services, domain communities, and various data formats. However, point cloud data has often been overlooked or treated in the same buckets as images or terrain. Today the use of point clouds is growing at a rapid rate in a variety of domains including utilities, mining, 3D modeling, etc. Point cloud data is currently stored in many formats. In many cases the formats were created for particular application domains. Some of these formats are now de facto standards in domains such as multi-dimensional scientific data, LiDAR data, elevation data, seismic data, bathymetric data, meteorological data, and fixed/mobile consumer sensors (IoT). OGC members have registered concerns that without development of best practices or consensus standards, divergence will continue and interoperability will be inhibited.

As an example, LiDAR data is commonly exchanged using the ASPRS LAS standard format. However, end-user consumption of LAS content for analysis or display requires indexing, optimization and/or compression of the content, with multiple methods available ranging from vendor-specific indexing schemes to commercial and free optimization and compression toolsets.  Further, more capable LiDAR encoding formats are being developed in specialized communities, such as the Sensor Independent Point Cloud (SIPC) based on HDF5.

The OGC membership is not necessarily advocating creation of a single point cloud encoding standard. Rather the members have expressed interest in ensuring greater interoperability between point cloud datasets and identifying methods to integrate such data to interoperate with other OGC standards.

The draft charter is available for review at https://portal.opengeospatial.org/files/64097. Comments should be sent via email to charter-requests [at] opengeospatial [dot] org and are due by 18 July 2015.

4 June 2015. At the June meeting of the Open Geospatial Consortium (OGC(R)) Technical Committee in Boulder, Colorado, USA, Paul Scarponcini, PE, PhD received the OGC's prestigious Kenneth D. Gardels Award (http://www.opengeospatial.org/ogc/awards). Carl Reed, PhD, who recently retired from his position as OGC’s CTO, received an honorary Gardels Award for his many years of Technical Committee leadership. The Gardels Award is awarded each year to individuals who have made an outstanding contribution to advance OGC's vision of geospatial information fully integrated into the world's information systems.

Over almost two decades, Paul Scarponcini, a Senior Information Architect at Bentley Systems, has been an important OGC Technical Committee contributor. He has also done much to help OGC advance spatial information technology standards in collaboration with other standards organizations. He helped develop some of the OGC’s foundational geospatial standards, and he has also played a pioneering role in bridging the critical gap between geospatial standards and information technology standards for the built environment. His years of technical leadership and liaison work in this area are now beginning to benefit information sharing in activities such as civil engineering, urban planning, facilities management and indoor location services.

The Gardels Award is the OGC’s highest honor bestowed upon a Consortium member representative. It is given annually in memory of Kenneth Gardels, a founding director of OGC and OGC's former director of academic programs. Mr. Gardels coined the term "Open GIS," and devoted his life to the humane and democratic uses of geographic information systems. He died at the age of 44 in 1999.

27 May 2015. The OGC is pleased to announce that Ordnance Survey (OS) has raised its Open Geospatial Consortium (OGC) membership level to become the first Strategic Member outside of the USA.

OS joins the US Department of Homeland Security, US Geological Survey, US National Geospatial Intelligence Agency and NASA as strategic members, reinforcing the company’s vision to be at the forefront of open standards development.

As a strategic member OS will use their skill and expertise to drive a collective and unified approach to promoting interoperability for the geospatial industry. The new membership will also allow OS to represent Europe, at a strategic level, to improve the quality of standards globally and to enable the industry to continue to innovate and grow.

“We are very pleased to have Ordnance Survey as a Strategic Member, OGC’s highest level of membership," said Mark Reichardt, President and CEO of the OGC. "OS’s continuing commitment to OGC – they have been a member since 1998 and a Principal Member since 2014 – reflects their strong commitment to the benefits of open standards. As a Strategic Member of the Consortium and as a leader in the international geospatial community, OS is positioned to play an even greater role in the development and implementation of OGC standards and in the international coordination of geospatial technology initiatives."

An important area of focus for OS will be the development of standards in the fast growing fields of Smart Cities, BIM (Building Information Models) and the Internet of Things. Geospatial data has an important role to play in these developing areas and the need for interoperability and common standards is critical to their long-term success. In addition to these emerging areas, OS will also continue to support development of global standards around the more traditional geospatial themes including web map services and 3D mapping, with a specific focus on day-to-day usability.

Neil Ackroyd, Acting OS CEO, added: “Open Standards are key part of achieving our business goals, but we also understand that they are vital to the industry as a whole.  We expect the new level of strategic membership to deliver significant opportunities to OS and allow us to use our skills and expertise to influence and drive new standards in the ongoing and future geospatial trends. I am particularly keen to see greater interoperability in the smart cities space.”

The new OS OGC Strategic Membership was officially announced at the World Geospatial Forum on 27 May 2015.

OS, Britain’s mapping agency, makes the most up-to-date and accurate maps of Britain. OS data and services help governments, companies and individuals be more effective both in Britain and around the world.

15 May 2015 – The Open Geospatial Consortium (OGC®) announces a Water Data Summit to be held at the UCAR/NCAR Center Green in Boulder, Colorado on June 3, 2015. This event is part of the June 2015 OGC Technical Committee Meeting.

The goal of the Water Data Summit is to stimulate engagement in development of tools and policies for the U.S. Open Water Data Initiative (OWDI). The Open Water Data Initiative will integrate different sources of water information into a connected, national water data framework and leverage existing systems, infrastructure and tools to underpin innovation, modeling, data sharing, and solution development.

Similar initiatives are being pursued in Europe, Australia, New Zealand and other regions. The main objective of this particular event is to acquaint the OGC community and the broader geoscience community with recent advancements in high-resolution forecasting of precipitation, runoff, streamflow, and flooding across the continental U.S. in near-real time. These advancements represent the first time that surface water flows have been modeled and studied at the national scale. Similar data and tools from the European Center for Medium-Range Weather Forecasting (ECMWF) in UK and the Joint Research Centre (JRC) in Italy are being applied on a global scale through the GEOSS Architecture Implementation Pilot.  The integrative framework, data and models being developed are enabling a major shift in the kinds of questions and issues scientists, meteorologists, and emergency response teams can start to address.

This research and development will be of interest to geoscientists in atmospheric and hydrological domains, as well as to operational meteorologists and even local-level public safety officials such as fire and police departments responsible for emergency response. The latter are among the key beneficiaries of this work.

For an agenda, details and registration, see the Water Data Summit web page. You must register to attend but there is no registration fee.
