OGC seeks public comment on candidate 3D Portrayal Service Standard

Description: 

In the last decade, progress in airborne and mobile laser scanning and photogrammetric methods has brought an explosion of terrain data and detailed 3D models of the built environment. The 3d models are often maintained in proprietary environments. The Open Geospatial Consortium (OGC) and the Web3D Consortium have both been working to address the need for interoperability, as well as the content challenges of volume, access speed, and diversity of devices. The Web3D Consortium has focused on open standards for real-time 3D visualization, including streaming, and their members developed a Geospatial Component extension for X3D. The OGC has focused on developing a service interface to provide interoperable access to 3D geospatial data servers. In 2012, a group of OGC members, building on work done in both organizations, completed the 3D Portrayal Interoperability Experiment (3DPIE) to develop and evaluate best practices for 3D portrayal services.

OGC seeks public comment on LandInfra Conceptual Model

Description: 

The membership of the Open Geospatial Consortium (OGC®) seeks public comment on the candidate OGC LandInfra Conceptual Model.

This document, the first public draft of the OGC's proposed UML conceptual model for land parcels and the built environment, communicates the proposed intent and content of a new candidate OGC standard to be called the OGC InfraGML Encoding Standard. The UML conceptual model establishes a single set of consistent concepts that could be implemented in GML (as InfraGML) or in other encoding mechanisms.

After reviewing the existing LandXML format, the OGC Land and Infrastructure Domain Working Group (LandInfraDWG) decided that a fresh start standard was warranted. The new standard would have a use case driven subset of LandXML functionality, but it would be consistent with the OGC standards baseline, implemented with the OGC Geography Markup Language (GML), and supported by a Unified Model Language (UML) conceptual model. Called InfraGML, this new standard would: be supported by a recognized Standards Developing Organization, OGC align with existing OGC (and TC211 and SQL/MM) standards, including the OGC Modular Specification benefit from functionality already supported by GML, including features, geometry, coordinate reference systems, linear referencing, and surface modeling (TIN) initially focus on alignments/roads, survey, and land parcels, the subject areas for which there are identified needs and committed resources for development using modular extensions, be able to expand into other areas (e.g., "wet" infrastructure pipe networks) as resources become available be use-case driven be based on a UML conceptual model developed prior to any encoding, such as GML have more up-to-date functionality be synchronized with the concurrent efforts by buildingSMART International in their development of Infrastructure-based Industry Foundation Classes (IFCs), and be more easily integrated with TransXML and OGC CityGML.

The document for the candidate OGC LandInfra Conceptual Model are available for review and comment below.  Comments are due by 22 February, 2015.

OGC seeks public comment on KML 2.3 standard

Description: 

The membership of the Open Geospatial Consortium (OGC®) seeks public comment on the candidate OGC KML 2.3 Standard.

KML is an XML grammar used to encode representations of places and objects for display in an earth browser, such as a 3D virtual globe, 2D web browser application, or 2D mobile application. KML can be used to accomplish various map and Earth image functions, such as: annotate places, specify icons and labels to identify geographic locations, create different camera positions to define unique views for KML features, define image overlays to attach to map views, and define the location and orientation of textured 3D objects.

The main KML enhancements provided in version 2.3 are:

  1. Addition of a new feature, KML Tour, which enables a user to specify aspects of a controlled virtual flight through a series of geographic locations, including speed, mode of flight (smooth or bounce), sound tracks and how KML features are updated throughout the tour.

  2. Addition of new geometries: Track and MultiTrack. A KML Track can capture and display the path and other aspects of  a moving object over a specified period of time.

  3. Enhancements to KML’s Extension Mechanism, allowing for the direct use of XML content from third-party schemas. KML 2.3 is now based on XML Schema 1.1 enabling Aauthors of KML Application Profile extensions are now able to experimentally add foreign element and attribute content interleaved among existing KML elements.

The documents for the candidate OGC KML 2.3 Standard are available for review and comment below.  Comments are due by 18 January, 2015.
