  • I would like to show you 2 of practices. one is about the disaster portal by neogeographers\n
  • The crisis mapping by openstreetmap supports the as the base map.\ uses openstreetmap as the basemap layer. Most of data mapped within 4 weeks and such rapid mapping encourages the report of The node data is mainly imported data of school, hospital, welfare facilities as the evacuation facilities. Tsunami damaged way and area is firstly drawn as the openstreetmap data by using arial photos provided by Microsoft Bing.\n

    1. 1. OpenStreetMap and theheavy rainfall disaster inthe mountainous area of Nara, Japan Yuichiro Nishimura*, Nara Womens University State Of The Map 2012 session: Disaster Relief I 09/06/2012 at 11:00 AM
    2. 2. my OSM C.V. SotM VenueOSM Kansai KyotoOsaka Nara • OpenStreetMapper in Kansai community (from Oct. 2010) and OSMFJ member © OpenStreetMap contributors, CC-BY-SA
    3. 3. my OSM C.V.• Human Geographer • interests: GIS and society• Education activity: OpenStreetMap in Nara Womens university• 2nd day(2:00pm -2:20pm) small Panel Discussion: State of the university/school GIS education using OpenStreetMap
    4. 4. movie
    5. 5. heavy rainfall disaster occurred in the mountainous area of Nara, September 2011• The heavy rainfall disaster occurred in Kii Peninsular, September 2011 has brought severe damage in the mountainous area of Nara Pref.• Tropical Storm Talas (2011) File:Talas_Terra_MODIS_picture_2011-09-02_(High_Definition).jpg
    6. 6. Totsukawa• It takes more than 4.5 hours Nara City between Totsukawa village (Nara Pref.) and Nara city by public transport (the distance is about 125km).• The largest village in Japan in terms of land area(The total area is 672.35 km² population:3,930,(2012))• several serious damage by Totsukawa heavy rain fall disasters • The huge disaster in Meiji-Era (1889) leads the migration to Hokkaido (to Shin-Totsukawa) © OpenStreetMap contributors, CC-BY-SA
    7. 7. • The heavy rain falls from Talas triggered huge landslides in the village• 73 people died and 20 more are still missing• The landslides occured on Sep. 3rd. in Totsukawa• The main roads also damaged by the landslide and outsider cannot enter the village over several months
    8. 8. crisis mapping• The state of the crisis mapping in Totsukawa will be shown• The imported data, traced data are mainly used on the crisis mapping• The limitation of such data leads the need of the field survey
    9. 9. crisis mapping• crisis mapping by most active OpenStreetMappers in Japan.• Thanks for mapping!!• Most of data mapped from 9th-13th Sep. 2011.
    10. 10. maps of Japanese mountainous area• relatively low quality by Google Maps – Google Japan uses zoomed map data by Zenrin 10 residential map mainly focused on the urban area.
    11. 11. making map • Yahoo! Japan/Alps: way data (imported in 20th, Aug. 2011) • Bing satellite image (trace) – mainly Coastal area (Shingu to Kushimoto) – no good resolution data in Totsukawa • GSI base map 1:25,000(WMS trace) 11
    12. 12. Bing image recently updatedWe can use high resolutionimage now(Though it is cloudy) 12
    13. 13. • The problems of scale -> the need of the field surveys – GSI base map 1:25,000(WMS trace) • sometimes the buildings and ways are omitted 13
    14. 14. • small roads 14
    15. 15. • suspension bridge• connection road 15
    16. 16. • evacuation houses• shops/bank• hotspring stand!! 16
    17. 17. disaster portal using crowdmap(
    18. 18. distribution of the reports
    19. 19. Sep. 11th: release of• crowdmap instance by Higa4 (OSMFJ)• checked tweet: #totsukawa, #十津川• The potential and limitation of the crowdmap is discussed at the OSM community in Japan – making good quality of the map before the disaster – roads and the communication line(telephone, internet, mobilephone) in the village had the damages • the methods for supporting the local resident • the difficulty of the field survey 19
    20. 20. Portal for recovery by Nara Pref. (Sep. 2012) • recovery planning • progress of plan • recovery mapping recovery mapping • recovery information • supporting information
    21. 21. using GIS
    22. 22. jpeg image only
    23. 23. Kumano Kodo• ancient religious roads• world heritage• The mapping for tourism• The mapping for disaster education • ancient road and settlements located at not the small flatland near the river but the mountain ridge
    24. 24. further issues• supporting OSM community building in the village (the practices by the outsider of the damaged area)• publicity of OSM is needed (Google maps have dominant position in Japan). The potential of OSM in mountainous area in Japan is not well known.• field surveys by local resident is needed for keeping the data quality.
