LiveE! Project: Sensing the Earth for Environmental Monitoring

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.

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
