OGC-Web3D MoU

• Develop and coordinate the production of appropriate joint outreach and marketing materials

• Develop and publicly publish exemplar hybrid content, which demonstrates the practical feasibility and effective value of using Web3D and OGC standards in concert

• Keep OGC and Web3D working groups informed about on-going technical progress and standards development strategies, in order to maximize interoperability and comparability between technology sets

OGC Geography Markup Language (GML)OGC Geography Markup Language (GML)

• XML-based language for encoding geographic information to be stored and transported over the Internet

• GML serves as a modeling language for geographic systems as well as an open interchange format for geographic transactions on the Internet.

• GML defines both the 2d and 3d geometry and properties of objects that comprise geographic information.

• Used – often based on policy - in UK, US, Germany, Canada, New Zealand, Holland, Hong Kong, Google

KML Encoding StandardKML Encoding Standard

• XML for geographic visualization on 2-D & 3-D Earth browsers

• Features for display: placemarks, images, polygons, 3D models, text, etc.

• KML is not a geospatial modeling language; consider GML

CityGML

• Application independent Geospatial Information Model for virtual 3D city and landscape models– comprises different thematic areas(buildings, vegetation, water,

terrain, traffic etc.)– data model(UML)acording to ISO 191xxstandard family– exchange format results from rule-based mapping of the UML

diagrams to a GML3 application schema– ongoing standardisation process in OGC

• CityGML represents– 3D geometry, 3D topology, semantics and appearance– In 5 discrete scales (Levels of Detail, LOD)

3D city modeling…

• …is far more than the 3D visualizationof reality

– In fact, the geometry and its appearance are only one aspect of an entity

– Key issue:Semantic modeling

– However: 3D city models often seen as being identical with 3D graphics/geometry models of the respective region• Google Earth (KML/COLLADA), X3D, 3D PDF, 3D Studio Max, etc.

CityGML and X3D - Examples

• Every instance is represented by a reference to the prototype – adopted from scene graph concept

• Class X3DMaterial is adopted from the X3D

• The definition of the appearance properties is adopted from the X3D specification

• Concept of positioning textures on surfaces complies with X3D

IndoorML

– IndoorML is a data model and exchange format for the representation of the indoor navigation aspects

GML3 application schema

– IndoorML provides well-defined interfaces to connect semantic models of topographic indoor space

Complementary to existing standards like CityGML and IFC Not restricted to 3D models e.g., Open Floor Plan

– Current research Extension to outer space e.g., GDF, OpenStreetMap Mapping of IndoorML to existing systems and vice versa
