  • Distinguished friends, I am TAKAGISHI from PASCO. The earthquake that struck Japan on Friday, March 11, is not only the most powerful earthquake to hit Japan in at least 100 years, but also one of the most powerful earthquakes recorded worldwide since 1900.
  • First, this is the overview of PASCO Corporation. We provide geospatial information with branches in 7 countries and our headquarter locates in Tokyo, Japan. We are now operating Advanced Land Observing Satellite, called ALOS, since April 2011. Our corporate mission is to establishes spatial information system to protect people’s life and safety, and To promptly grasps the situation of affected areas and supports humanitarian and recovery efforts when disaster occurs. まず、パスコの概要です。パスコは日本を中心として各国に拠点を置いており、地理空間情報サービスを提供してます。 2011 年 4 月からは ALOS 運用事業者となっています。 パスコの社会的使命には、 ・地理空間情報を活用し、人々の生活や活動を支援すること ・災害時には、迅速な被災状況の把握や人命救助、復旧・復興を支援すること が挙げられ、次のようなプラットフォーム・センサを用いて災害モニタリングを実施しています。
  • PASCO has a long history to provide aerial photogrammetric, survey and GIS services in Japan since 1953 and dominates the national mapping industry. PASCO has expertise for the disaster monitoring. This slide shows our concept for the global disaster management by constructing integrated social system. ( READ the slide contents…)
  • Immediately after the massive earthquake and tsunami, PASCO analyzed and delivered disaster information gathered by various sensors from the ground, air and space.
  • PASCO started acquisition of information from the space, air and ground immediately after the earthquake on 3/11 (three eleven). And the analyzed information were delivered to the ministries, agencies and other customers.
  • We have distributionship for the various commercial optical and SAR satellites. PASCO is the prime distributor for the ALOS and for exclusivity for TerraSAR-X and Tandem-X in Japan. We have 2 ground receiving stations also, Okinawa and Hokkaido.
  • Satellites showing in RED were utilized for the Great East Japan Earthquake
  • This shows the production flow chart for providing the information for the flooded areas. 61 images of WorldView, 44 scenes of ALOS, 40 scenes of RapidEye and 40 scenes of TerraSAR-X were acquired and processed. A total of 195 scenes were processed for the entire region of 560, 000 sq km. Identification were done by the experts and GIS data were built and maps were created. Created products were as : O verview Map, Detailed Map, Size of flooded areas by municipality, and Map for GIS polygon data (SHP, KML). Whole production was done in one week, from March 12 to 18.
  • This shows our actions within 72 hrs.. ( READ the contents of each DISAS.TER, 24 hrs, 24 hrs, 72 hrs)
  • We performed (did) the automatic difference extraction between post- and pre-disaster acquisitions of Terra-SAR X images. This allowed us to quickly estimate the inundation areas from Ishinomaki and Sendai Airport in the same day of data acquisition. Dark red areas shows inundation areas. The map was prepared in 6 hours after satellite data acquisition.
  • PASCO was round-the-clock active to acquire the data from the satellite, airplane, helicopter and mobile mapping system. Maps of the flooded regions were produced for the March 13, 15, 16 and provided to the agencies on 17 and 18 March. We also produced the maps showing the estimated amount of debris . (READ more, depending upon the total speech time).
  • This shows the estimated flooded areas of 500 of length. Area covered the Coastline from Aomori to Ibaraki pref. Flooded areas by tsunami were extracted and mapped based on pre- and post-disaster images of TerraSAR-X, WorWorldView-2, RapidEye, ALOS, Spot 5, and EROS-B. The background data as 1:25,000 PASCO FreshMap with Political boundary, river, road was utilized. These maps were delivered to disaster prevention agencies such as Ministry of Land, Infrastructure, Transport and Tourism, affected local governments and news media.
  • Shown here is the detected changes of the estimated flooded areas. TerraSAR-X images were acquired 5 times since Mar. 13 and automatic extraction of the flooded areas were conducted. The images of the left sides shows daily change detection. On the left, shows the summary of the change detection between March 13, 24 and April 4.
  • This shows the flooded area extracted automatically utilizing temporal acquisition of the TerraSAR-X data. The areas in pink, orange and red show estimated inundation areas of March 13, 24 and April 4, respectively. Maps delivered to Ministry of Land, Infrastructure, Transport and Tourism. ( READ the slide contents if you have more time during speech).
  • PASCO created and delivered the maps and related information to the emergency managers of various agencies in a shortest span of time. We published the information on the web site as free access. Analyzed results were also published on major newspapers in Japan.
  • Coming to the summary, PASCO acquired data from different resources (satellite, airplanes, helicopter and vehicles). Entire affected areas were covered & mapped. Data processing were conducted immediately. This also included field surveys. And finally, data were provided within hrs and days. (Or, READ, he slide contents ). PASCO is committed to provide the dedicated services for the disaster monitoring..
  • Thank you.
