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 OASIS
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 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 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
–

GeoPDF
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
