location and geospatial topics across multiple SDOs
– Geopriv, IEEE, ISO, OASIS
• OGC support of emergency service architectures
– OGC Web Services

What is the Open Geospatial Consortium (OGC)?
OGC Membe rship Dis tributi on
By Re gi on
• 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 Me mbershi p Di stri bution

OGC Mission
To lead in the development, promotion and harmonization of
open geospatial standards …

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)
• 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 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 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.

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

GeoPDF
• 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)
• 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

• Multiple thematic areas
(buildings, vegetation, water, terrain, traffic etc.)
• Data model (UML) according to ISO 19100 standards
• Exchange format: rule-based mapping of UML to GML3
• Adopted OGC standard since 2008

CityGML : 5 levels of details
LOD 4 – Interior Model
“Walkable” architectural models
LOD 3 – City / Site model
Detailed architectural models, landmarks
LOD 2 – City / Site model
Simple buildings with detailed roof structures
LOD 1 – City / Site model
Prismatic buildings without roof structures
