Presentation Transcript
new at google
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
google statistics
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
google data infrastructure close to your network
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)

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

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
where 2 0 highlights
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,…

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)

where 2 0 highlights open source geo
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
where 2 0 highlights open source geo15
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)

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)

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

  • Allan Doyle (key contributor to the specification)
summary
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

response
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?
