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
Open Geospatial Consortium
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 showing 64 Mars layers; many PDS released-but most datasets required conversion
GIS = Integrated Geospatial Environmentfor mapping and analysis

Brief Project Highlights Develop planetary datum and projection and register
them with OGC Develop WMS and WCS servers for Mars and Lunar
data Interoperate with other planetary servers Propose integration of servers into the Planetary
Data System
