  1. Mass-market Geo: Emergingtrends and standardsSept. 12, 2006B.McLeod, CCRS/GeoConnections

  2. Google Developer Day – June 12, Googleplex, Mountain View, CA

  3. “Life inside the Googleplex” www.time.com

  4. Systems Engineering – Google road map

  5. “100 foot” rule

  6. Opening session: Sergey Brin, Larry Page, Eric Schmidt

  7. New at Google… • Positioning of Google Earth (new release) as “the geobrowser” for the Web with KML as the “markup” language • Street level geocoding addition to Google Maps API (limit 50,000 address/day) includes Canada, US, France, Italy, Germany, Spain and Japan) • New satellite data • - four times more land mass covered in hi-res • New focus on building the 3D world (Sketchup modeling tool) and local content • KML for Google maps • Enterprise version licensing model

  8. Google statistics • 100,000,000 downloads of Google Earth • 30,000 users of API • 1/3 of world’s population can now “see their neighbourhood” • 12 new employees/day • 1400 job openings

  9. Google data infrastructure (“close” to your network) • Google-container • 10m box • 5000 Opteron processors • 3.5 petabytes disk • Transportable by tractor-trailer • This shipping container is a prototype data center. Google can “park” containers close to major Internet peering points/hubs • Google server farms • 2003: 1 • 2005: 64 (est) • 2007: 300 (est)

  10. Where 2.0™ Conference: June 13-14, San Jose, CA • O’Reilly conference • Primary Tracks: • Geoportals/mashups • Gaming • Location-based services • Open source geo/open data

  11. Where 2.0™ : O’Reilly, June 13-14, San Jose, CA • Key geo-portal providers • Google (Maps/Earth), Microsoft (Virtual Earth/windows live local), Yahoo (Yahoo local), Mapquest • Portal providers also provide APIs for application developers • “Mash-ups” combine data with Map content • - estimate of 10,000 Google Map mash-up applications • - e.g. http://www.beerhunter.ca/OttawaArea

  12. Where 2.0 highlights… • “Web 2.0” is the “read-write” Web (participatory Web) Local content – new focus for Geoportal providers simple geotagging (address, postal/zip code, etc.) allows anyone to publish geodata - weather, business, social networking information, 3D building models,…

  13. Where 2.0 highlights… • “Web 2.0” is the “read-write” Web (participatory Web) Local content – new focus for Geoportal providers simple geotagging (address, postal/zip code, etc.) allows anyone to publish geodata - weather, business, social networking information, 3D building models,… from many sources - high-res satellite (Google - new imagery, Microsoft – bird’s eye) - syndication feeds, general public - minimal metadata - issues: authoritativeness, privacy, licensing/IP rights - Wikipedia model for Geodata? (e.g. Open street map)

  14. Where 2.0 Highlights – Open Source GEO • Open Source GIS maturity • Geospatial IT “evolution of mainstream IT” thru standards (GML, Simple features, SQL/MM, OGC W*S services) • Core geospatial standards available thru Open Source (Mapserver, Geoserver, PostGIS,…) • Mapserver now is the number 2 “Web mapping” platform – estimated 50,000 sites

  15. Where 2.0 Highlights – Open Source GEO Open Source Geo Foundation – OSGEO.org • Founded Feb, 2006 • Mission: “to support and promote the collaborative development of open geospatial technologies and data” • Home for all leading Open Source mapping/geo initatives • Contribution of MapGuide s/w from Autodesk, and initial funding for establishment of foundation • Key components/projects: Mapserver, GeoTools, GDAL, Grass, MapGuide, MapBender, MapBuilder, OSSIM Additional info: Free and Open source software for Geomatics conference (this week in Lausanne)

  16. Where 2.0 highlights - STANDARDS • - KML and GeoRSS frequently mentioned in presentations • GeoRSS can allow for syndication feeds for Geo content • Abstract encoding for point, line, polygon and box • Two XML encodings: “simple” and GML (subset of GML simple feature profile)

  17. Where 2.0 highlights – STANDARDS • - KML and GeoRSS frequently mentioned in presentations • GeoRSS can allow for syndication feeds for Geo content (use with RSS, Atom) • Abstract encoding for point, line, polygon and box • Two XML encodings: “simple” and GML (subset of GML simple feature profile) Point (GML) • <georss:where> • <gml:Point> • <gml:pos>45.256 -71.92</gml:pos> • </gml:Point> • </georss:where>

  18. STANDARDS: GeoRSS examples <georss:where> • <gml:Polygon> • <gml:exterior> • <gml:LinearRing> • <gml:posList> • 45.256 -110.45 46.46 -109.48 43.84 -109.86 45.256 -110.45 • </gml:posList> • </gml:LinearRing> • </gml:exterior> • </gml:Polygon> • </georss:where>

  19. STANDARDS: GeoRSS example – real-time traffic feed http://api.local.yahoo.com/MapsService/rss/trafficData.xml?appid=YahooDemo&zip=90210

  20. STANDARDS: GeoRSS Implementation Implementation of GeoRSS • Microsoft Virtual Maps • Yahoo Maps API • ESRI ArcWeb Services API • Cadcorp SIS • other, interest from Google, but no formal support

  21. STANDARDS: GeoRSS Additional info Addition info: • www.georss.org • OGC white paper: http://www.opengeospatial.org/pt/06-050r3 • Allan Doyle (key contributor to the specification)

  22. Summary • Simple standards = significant uptake (10,000 Mash-ups 1 year after Google API released) • Lower the bar for Geo-Application developer - Typical OGC standard “learning curve” is two-three months (e.g. WFS/GML) - Typical Google API “learning curve” is two-three days - Microsoft, Yahoo APIs are more rich increased learning curve Standards Process - significant emerging defacto standard (e.g. KML) J. Dangemond stated that ESRI will publish content in formats “to be mashed-up” - “open” standards development process (e.g. GeoRSS) being executed outside OGC/ISO; market-driven

  23. Response? • Consumer-geo does raise the bar for geo-applications in terms of: • Accessiblity (non-expert); usability (performance and ease-of-use); content integration, content depth/breadth; new “open data” content suppliers; large scale replicated data warehouse; uptake • Increasing maturity level of Open Source Geo market and alignment with mainstream IT • Impact on Architecture for SDIs and GEOSS?
