The Open Geospatial Consortium (OGC) seeks public comment on the candidate standard jointly developed by the International Organization for Standardization (ISO) and the Open Geospatial Consortium: “Geographic Information - Well-Known Text representation of coordinate reference systems” (CRS WKT).
Well-Known Text (WKT) is used as a compact machine- and human-readable representation of geometric objects and coordinate reference information, as specified two decades ago in the OGC and ISO standard “Geographic information – Simple feature access – Part 1: Common architecture.” This standard included a capability for describing coordinate reference systems as text. The original CRS WKT was subsequently extended in numerous incompatible ways, and had thus become non-interoperable.
In 2015, OGC and ISO adopted a major revision of the CRS WKT specification that allowed a rigorous description of coordinate reference systems and coordinate operations in WKT, following the data model described in OGC Abstract Specification, Topic 2, which is also published as ISO 19111:2007 - Spatial referencing by coordinates. However, OGC AS Topic 2 and ISO 19111:2007 have recently been revised. The revision of CRS WKT tracks the changes made to the CRS data model.
The new edition of the CRS WKT standard aligns with the coordinate reference system model described in ISO 19111:2018. Specifically the changes from the 2015 edition are:
Extension to describe dynamic geodetic and dynamic vertical coordinate reference systems - coordinate reference systems in which coordinate values on the surface of the earth change with time due to tectonic deformation including a time reference (coordinate epoch) for coordinates referenced to a dynamic CRS;
Extension to describe geoid-based vertical coordinate reference systems;
Extension for the description of datum ensembles, groups of realizations of one terrestrial or vertical reference system that for low accuracy purposes may be merged ignoring coordinate transformation;
A rigorous description of temporal coordinate reference systems;
The removal (deprecation) of image coordinate reference systems; and
The remodelling of scope and extent information.
This latest edition of CRS WKT cancels and replaces the 2015 version (also published as ISO 19162:2015), which has been technically revised. The candidate CRS WKT standard was prepared by the OGC CRS Standards Working Group and Technical Committee ISO/TC 211 Geographic information/Geomatics.

OGC seeks public comment on proposed Statistical Domain Working Group

Thu, 07/26/2018 (All day)
The Open Geospatial Consortium (OGC) seeks comments on the draft charter of a proposed Statistical Domain Working Group (DWG).
The Statistical DWG is proposed to identify requirements and use cases of how geospatial and statistical standards can support the integration of geospatial information into statistical systems for the purposes of broad discovery, analysis, and use.
The statistical domain is evolving to move from the traditional capture of data through surveys such as census, to a more dynamic integration of data from across a wide range of domains that can make statistics more timely, more accurate, and better understood.
Geospatial information is a key data source in transforming the way that statistics are produced as it has the potential to fit into every component of the Generic Statistical Business Process Model.
The complexity of bringing together survey, administrative, and big data with geospatial information and earth observation is driving an increased need for standardisation to support better statistical outputs. A few of the specific challenges under consideration within the proposed DWG include:
Data integration – how can semantic web technology be used to improve the integration of geospatial and statistical datasets?
Data Capture – how can geospatial data be used to include the capture and georeferencing of survey, administrative and big datasets used in the production of statistics?
Data processing – as geospatial objects do not fit within traditional database structures these are currently handled externally to the rest of the statistical process through dedicated geospatial systems.
Data exchange – given the lack of interoperability between statistical and geospatial data architectures, frameworks, metadata and standards, how can data be shared through a service orientated approach?
Data analysis – a lack of comparability between geographic datasets at a national, regional, continental and global level makes international analysis difficult.
Knowledge – there is a lack of understanding within the statistical community of the geospatial tools and standards that can support the statistical system, and a corresponding situation with the geospatial community.

OGC Seeks Public Comment on new version of OpenSearch for Earth Observation Suite of Standards
Please note: This Request is scheduled to close on 3rd August 2018.

The Open Geospatial Consortium (OGC) seeks public comment on the latest version of the OpenSearch for Earth Observation (OpenSearch-EO) Suite of Standards.
The OpenSearch specification allows syndication of search results that can then be aggregated by one large index. It provides a simple to use description of the search interface, which is called OpenSearch Description document (OSDD). A client (e.g., a browser) can use this description to check which response formats are supported and how a query/filter can be formulated.
This OGC suite of standards specifies an Earth Observation extension to OpenSearch (OpenSearch-EO) that defines query parameters to permit the filtering of search results with fields related to Earth Observation, as well as a search response model supporting different search response encodings. This revision updates the extension primarily to include additional examples for developers. Further, two new encodings of the OpenSearch-EO conceptual model have been developed as new standards: one for encoding metadata using GeoJSON or JSON-LD and one for encoding of responses to OpenSearch-EO queries in GeoJSON or JSON-LD. These standards further integrate with the OGC Standards Baseline in that the GeoJSON responses are provided as OWS Context documents.
OpenSearch-EO specifies a series of parameters that can be used to constrain search results. In short, provision is made to filter results by sensor information, acquisition, processing parameters and other information.
This specification is complementary to the OpenSearch Geo and Time Extensions (OGC 10-032 [RD.3]) and recommends its use for spatial and temporal queries especially for EO collection and EO product metadata. Further, it defines a default response encoding based on Atom 1.0/XML [RD.22].

OGC Seeks Public Comment on 3D Tiles Candidate Community Standard
Please note: This Request is scheduled to close on 1 August 2018.
3D Tiles is a publicly available open specification for streaming massive heterogeneous 3D geospatial datasets for visualization. To expand beyond existing 2D and 2.5D streaming of map tiles and terrain, 3D Tiles support 3D models such as point clouds, 3D buildings (exterior and interior), trees, imagery, BIM/CAD models, and terrain. 3D Tiles is currently implemented in more than a dozen software products.
Batched 3D Models – for 3D buildings, terrain, BIM/CAD models, etc.
A Community standard is an official standard of the OGC that is developed and maintained external to the OGC. The originator of the standard brings to OGC a “snapshot” of their work that is then endorsed by OGC membership as a stable, widely implemented standard that becomes part of the OGC Standards Baseline. In 2016, OGC approved a work item on endorsing 3D Tiles as an OGC Community Standard, and now this effort is ready for consideration for approval by OGC members.

OGC seeks public comment on Part 1 of the Features and Geometries Candidate Standard
Please note: This Request is scheduled to close on 27 July 2018.
The Open Geospatial Consortium (OGC) seeks public comment on Part 1 of the Features and Geometry candidate standard.
The Features and Geometries candidate standard provides the requirements for defining and representing geographic features in geographic information systems, applications, databases, and data formats. This standard is being developed in multiple parts in conjunction with ISO / TC 211 and will impact or replace ISO 19107, ISO 19109, and ISO 19125. The major advantage to the approach taken with the multi-part Feature and Geometries standard is that the parts are each relatively small and focused in content and ease the burden of implementation of the standard.
The Implementation Standard Geographic information — Features and geometry – Part 1: Feature models describes how geographic information held in datasets and databases using a ‘feature model’ are structured, created, stored, queried, and manipulated.
Part 1: Feature models updates the General Feature Model with various representations, as well as how it determines the basic form of geographic information. This is derived from and extends ISO 19109, which, in its current form, only addresses schema-based data storage defined in UML, but leaves possibilities open for other non-schematic design systems.
The data structures described in the candidate standard have been made more flexible than in earlier versions of this and supporting standards. The Features and Geometry standard describes semantically-structured data sets aimed to represent reality, not the specific needs of a single application. This shifts the support of interoperability from creating transfer formats, to creating inclusive, flexible - and thereby interoperable - data stores that are usable by a wide range of applications.
Further parts will describe the distinction between planar and geodetic/ellipsoidal geometry, simple geometries, other geometry, and topology structures, while a set of parallel standards will define WKT (well-known text) and JSON (JavaScript Object Notation) for both features and geometry.

The Open Geospatial Consortium (OGC) seeks comments on the draft charter of a proposed Earth Observation Exploitation Platform Domain Working Group (DWG).
For example, a scientist assessing climate changes may need data across several providers - from vegetation indexes, to predictive rainfall models and more - in order to answer a research question. Standardized elements of EO Exploitation Platforms could provide a single interface for this climate scientist where each ‘cloud’ talks to each other in the background, sharing the data, applications, tools and services between the platforms to generate a final ‘picture’ for the scientist.

OGC seeks public comment on new Interoperable Simulation and Gaming Domain Working Group
Please note: This Request is scheduled to close on 28 May 2018.
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
