Tile standard for streaming 3D content

The Open Geospatial Consortium (OGC) has approved the 3D Tiles Specification 1.0 for adoption as an OGC Community Standard. The specification is designed for streaming heterogenous 3D geospatial content to clients for visualisation. Expanding beyond traditional 2D and 2.5D streaming of maps and terrain, 3D Tiles supports 3D models such as point clouds, 3D buildings (exterior and interior), trees, imagery, BIM/CAD models, and photogrammetry. It is currently implemented in more than a dozen software products. The specification defines a spatial data structure and a set of tile formats designed for 3D, and optimised for streaming and rendering. These tile formats include batched 3D models (for 3D buildings, photogrammetry, BIM/CAD models); instanced 3D models (for trees, bolts, valves); point clouds (including per-point attributes) and composite formats (for aggregation of tiles of different formats).

Updated guidelines on assessing information security controls

Developed by ISO and the International Electrotechnical Commission (IEC), ISO/IEC TS 27008, Information technology – Security techniques – Guidelines for the assessment of information security controls, provides guidance on assessing the controls in place to ensure they are fit for purpose, effective and efficient, and in line with company objectives. The technical specification has recently been updated to align with new editions of other complementary standards on information security management, namely ISO/IEC 27000 (overview and vocabulary), ISO/IEC 27001 (requirements) and ISO/IEC 27002 (code of practice for information security controls), all of which are referenced within. The technical specification can help give organisations confidence that their controls are effective, adequate and appropriate to mitigate the information risks the organization faces. It is of benefit to organizations of all types and sizes, be they public, private or not-for-profit, and complements the information security management system defined in ISO/IEC 27001.

Environmental linked features interoperability experiment

Interested parties are invited to participate in the OGC’s Second Environmental Linked Feature Interoperability Experiment. The experiment is one part of an ongoing initiative to build a web of environmental data in such a way that it is easily and reliably discovered, navigated, and used by contemporary web developers. In recent years environmental domain data models have been established, but there is no best practice or standard methodology to encode documents that link features in different domains (e.g. rivers, aquifers, or soils) with observational data about those features. A common approach to encoding such links is required to allow cross-domain and cross-system sharing and interoperability of such linked information. The new experiment will design and vet a web-resource model for APIs to follow as well as network behaviour for cross-domain linked feature data that complements and uses WFS3 as a building block. It aims to answer the question “How do we use linked data in a way that is compatible with W3C best practices and leverages OGC standards?” The kick-off will be held via telecon on 29 April 2019.

Routing and marine pilot projects

The OGC launched two pilot project in February 2019: The Maritime limits and Boundaries Pilot and the Open Routing API Pilot 2019. An active OGC membership is required to participate in both these pilot projects.

The Maritime Limits and Boundaries Pilot will advance an implementation model, architecture, and prototypes for sharing Maritime Limits and Boundaries (MLBs) while adhering to the requirements of the United Nations Convention of the Law of the Sea. The International Hydrographic Organisation (IHO) developed the S-121 Maritime Limits and Boundaries standard, which supports the digital data structure and exchange formats for maritime limits and boundaries. This interoperability pilot will help to progress the implementation of the S-121 standard. The pilot will advance the implementation of the S-121 data model and architecture, and will implement operational prototypes to support the creation, management, integration, dissemination and onward use of official data for maritime baselines, limits, zones and boundaries.

The goal of the Open Routing API Pilot 2019 is to develop an API that allows requesting routes from different providers in a coherent, standardised way via web protocols. The pilot will develop a route model and web-friendly API to be served by the latest generation of OpenAPI-based Web Processing Services. Road network data, routing and navigation algorithms, as well as implementations for route calculation, are available from many providers and sources. The pilot project aims to address interoperability issues and expand the ability of routing services to incorporate diverse data, routing algorithms, and planning parameters in a standardised way. It will generate a JSON-based route model for route exchange, comparison, and integration. The pilot will also use next generation OGC Web Service interface definitions based on OpenAPI to define an API for interacting with route services in a standard manner.

Rail-themed integrated digital built environment workshop

The OGC will host a rail-themed Integrated Digital Built Environment (IDBE) Workshop on 1 April 2019 in Switzerland, preceding the IDBE subcommittee meetings. The results of this workshop will provide input for the subcommittee to align the roadmaps of the relevant working groups within OGC and BuildingSmart International. The workshop will focus on rail-related use cases and the requirements for interoperability between applications in this industry. The workshop is organised in four sessions building the requirements, existing efforts and practices, and next steps for standardisation of railway data in both the geospatial and BIM contexts. It is intended for professionals and researchers working in infrastructure design, construction, operation, and mapping, especially those from the rail industry. Participants can share their experiences, learn of the latest developments in standardised data exchange, and influence the evolution of standards to best fit the needs of the rail domain. Registration for the event is free but mandatory. More info here.
