  1. Live E! Project : sensing the Earth Masaya Nakayama†,SatoshiMatsuura‡, HiroshiEsaki†,HidekiSunahara‡ †Univ. of Tokyo/WIDE Project ‡NAIST/WIDEProject

  2. Background • In the 21st century, people has risen the concern about environmental problems. • Heat island phenomenon in the city part • Large-scale hurricane has occurred • At Feb. 2005, UN issued Kyoto Protocol. • Each developed countries try to reduce CO2 generation. (Japan – 6%, US – 7%, EU – 8%)

  3. Observation Status (in Japan) • AMeDAS (Automated Meteorological Data Acquisition System) has been operated from Nov. 1974 by JMA (Japan Meteorological Agency). • Rain fall 1300 places • Wind dir, Wind speed, Temperature, Sunshine duration 850 places • Snow depth 240 places

  4. Observation places by AMeDAS http://www.kishou.go.jp/know/kansoku.html

  5. AMeDAS (Tokyo)

  6. AMeDAS (Okayama)

  7. Background • Observation places are not enough for understanding the detailed phenomena (especially city area) of earth. • Observation of earth phenomena using small sensors which are connecting to the Internet is important.

  9. Interoperability test of sensor nodesin 2001

  10. An example effect of sensor nodes(Energy saving at HQ of Matsushita Works)

  11. OverviewofLiveE! architecture

  12. Currentarchitecture of system

  13. AMeDAS (Tokyo)

  15. Example observation results (Kanto)

  16. Temperature (City Area) 2006/01/01-2006/01/19

  17. Temperature (around city) 2006/01/01-2006/01/19

  18. Temperature (Kanto Area) It may be an effect of heat island phenomena. 2006/01/01-2006/01/19

  19. Details of data format/API • Many types of sensors are sold in market. • We need an interoperable exchange format between sensors. • Limited conditions of observation places • We cannot make uniform situation about observation conditions • We need profile information about observation places

  20. Several observation places Univ. of Tokyo Junior High School at Kurashiki, Okayama Elementary School at Minato-ku, Tokyo

  21. Sensor Information • Current sensor information • Temperature deg C • Humidity% • PresssurehPa • RainFallmm/h • WindSpeedm/s • WindDirdeg • CO2 ppm

  22. SensorProfileInformation • CurrentSensorProfileInformation • addressphysicaladdressofsensor • locationlocationname • ipAddrIPv4address • ip6AddrIpv6address • latitudelatitudeofsensor • longitudelongitudeofsensor • altitudealtitudeofsensor

  23. Sample SOAP services • getCurrentDataAll() • getCurrentDataByType(sensorType) • getCurrentDataByAreaRect(x1, y1, x2, y2) • setProfile(xmlDocument) • getProfileAll() • getProfileByType(sensorType) • getDataByTimespan(sensorID, startTime, endTime) • putData(xmlDocument)

  24. Sample Code #! /usr/local/bin/perl –w use encoding ‘UTF-8’, SDOUT => ‘shiftjis’; use SOAP::Lite; $service = SOAP::Lite -> service(‘http://example.com/axis/ DataProvider?wsdl’); $currentData = $service->GetCurrentDataAll(); print $currentData;

  25. XML document from Live E! DB

  26. Example Interfaces for Live E! users

  27. Weather Information Viewer for educational usage

  28. An Example application with GoogleEarth

  29. Summary • Introduction of Live E! project • Observation of Earth phenomena using sensor nodes with internet connectivity • Share such digital data between people who wants to use for several purposes • We define XML formats and SOAP services to share digital data • Example user interfaces by Live E! project • GoogleMap interface • GoogleEarth interface
