Mapping, Data Dissemination, The Web & Interoperability Deborah Lee Soltesz and Trent Hare

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

define: Web Services

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 )  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 Topics  CRS support  Promote Planetary Name Space (i.e. planetary EPSG)  Implement CRS Registry Service  Work 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 Environment for mapping and analysis

MORE - Planetary OGC Examples NASA’s Worldwind accessing JPL’s OnMars WMS server (16 bit Png for elevation, Image texture, topography colorized using SLD) 2X

Planetary OGC Examples JMARS (Mars Odyssey THEMIS Mission Planner) By Arizona State University

Planetary OGC Examples USGS Servers Map-a-Planet, PIGWAD, Nomenclature, and UPC

Multiple Servers Working Together

WMS Connect (client builds local layers ) Novel approach to use WMS servers

Astro Web Server Interoperability Project  Gazetteer of Planetary Nomenclature  Planetary feature data availability  Geocoded RSS  Web Feature Service  Planetary Map Index  Catalog of published planetary map  Geocoded RSS  Web Feature Service  Map-a-Planet  Planetary global mosaics  Web Map Service

Astro Web Server Interoperability Project

Astro Web Server Interoperability Project Example: Gaia Map Viewer

Astro Web Server Interoperability Project Example: NASA World Wind access Map-a-Planet

 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 OnEarth to OnMars, OnMoon
