Mapping, Data Dissemination, The Web & Interoperability

Standards and Interoperability

The ability for disparate systems to exchange information Web Interoperability: web pages are viewable

using any standard browser on a personal computer, portable device, or other appliance

Semantic Web: uniform, machine-to-machine data interchange

Web Services: uniform, machine-to-machine communication, interaction, and data interchange

Web Standards

World Wide Web Consortium (W3C) Popular Standards: HTML, XML, HTTP, URL Web Services Standards: WSDL, SOAP Data interchange standards: RDF, OWL

Open Geospatial Consortium (OGC) Data interchange standards: GML, GeoRSS,

GML/Jpeg2000 Geospatial Web Service Standards: WMS,

WFS, WCS, WPS

Benefits to Using Standards

Take advantage of existing desktop and web applications Reach a wider audience Make finding and using data easier for users Simplify sharing our data and maintaining

systems Standards survive the test of time

Current Planetary Work in the OGC Planetary Working Group (charter posted,

pending doc. 05-100) Planetary namespace defined – submitted, to

define Coordinate Reference Systems (CRS) Invited to test GML/JPEG2000 for planetary On the CRS, WCS and WPS working groups

Need more planetary members

Priority Planetary OGC TopicsCRS support

Promote Planetary Name Space (i.e. planetary EPSG)

Implement CRS Registry ServiceWork with client software to better support planetary CRSs in WMS (but really all -- W*S standards)

GIS = Integrated Geospatial Environmentfor mapping and analysis
