OGC Membership Distribution
By Region• An International Voluntary Consensus
Standards Organization, founded in 1994.
• 400 members and growing: industry, government, research, university
• 28 implementation standards
• Hundreds of product implementations in the market
• Alliances and collaborative activities with many other SDO’s

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 geometry and properties of objects that comprise geographic information.
• Used in UK, US, Germany, Canada, New Zealand, Holland, Hong Kong, Google

GML and IETF PIDF Location Object (LO)GML and IETF PIDF Location Object (LO)
• Presence Information Data Format (RFC 4119)– The PIDF LO RFC extends PIDF to allow the encapsulation of location
information within a presence document.
– (PIDF) is a common presence data format for CPP-compliant presence protocols, allowing presence information to be transferred across CPP-compliant protocol boundaries without modification, with attendant benefits for security and performance.
• Why?– Without this standard, cannot provide sufficient Presence Service
• GeoPriv Working Group in IETF developing a GML GeoShape Application Schema for use in internet standards.– Approved as OGC Best Practices paper, December 2006
• Now a mandatory requirement for expressing location in a variety of internet standards

Use of GML by OASISUse of GML by OASIS
• There is now a GML Oasis Application Schema for use in a variety of OASIS standards. This application schema was developed by OGC staff and members and submitted to OASIS.– Is now being used in HAVE– Is now being used in EDXL-RM– Both CAP and EDXL-DE revisions will incorporate this
work.

GeoRSS GMLGeoRSS GML
• GeoRSS – Simple encoding for location for RSS feeds
• GeoRSS GML – Points, lines, polygons, and rectangles.
• Broadly implemented, including support in MS LiveLocal, Google Earth and Google Maps API
• Consideration to bring this GML schema into the OGC for approval.

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

Web Map Context Web Map Context
• Captures state information of Web Map Service request so the information can be shared for collaboration– XML document includes: server URLs, window size and
placement, bounding box, and other details– OGC standard now
• OWS Context for more general contents– Sharing of state for services beyond WMS– Under development in OWS-7 Testbed– Engineering Report in June 2010

GeoPDFGeoPDF
• GeoPDF specifies “map frames” associated with a PDF page– Map frame describes relationship between a coordinate reference
system and an area on the PDF page. – Three types of coordinate reference systems supported:
geodetic, projected and unregistered Cartesian (Engineering)
• GeoPDF is an OGC Best Practice – BP publish “as is” to support the large number of GeoPDFs that
have been published to date.– Working with community to develop standard

Open Location Services (OpenLS)Open Location Services (OpenLS)
• OpenGIS Location Services (OpenLS) An open (middleware) platform for location-based application services for
mobile assets and terminals. The primary goal of the OpenLS initiative series is to define the specifications
for the “Core Services and Abstract Data Types (ADT)” that comprise this platform.
• OpenLS : Core Services Standard– Part 1-Directory Service – Part 2-Gateway Service– Part 3-Location Utility Service(Geocoder/Reverse Geocoder)– Part 4-Presentation Service– Part 5-Route Service

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
