9 Need for Space Technology Disaster Situation Attributes Time? of Disaster Occurrences Location? Spatial Component Source (point, line or area) Area of Impact (line or area) Near real time Satellite and Airborne information Community Media Police and Military Authorities Disaster Management Authorities Actions Emergency Operations Evacuations Rescue Operations Can capture large extent spatially and able to identify source, area of impact and further development?

10 Sentinel Asia helps DRM in Sri Lanka However facility to receive near real time satellite imageries to countries like Sri Lanka, is limited. To overcome this, an regional mechanism were initiated called Sentinel Asia. Satellite Observation Information Provision Disasters Data Utilization Space Agencies Human Network Disaster Management Agencies

11 ALOS2 KOMPSAT-1 PALSAR: m L-Band Ministry of Disaster Management is a member of JPT since 2008 Disaster Management Centre officially started SAS Operations since THEOS February 2009 Up to now 07 emergency observations had been conducted successfully Became Data Analysis Node (DAN) in 2010 PAN: 2m Multi: 15m WINDS receiver has been established in 2011 Sentinel Asia regional server / WINDS Receiving Antenna Established Feb. 2015

20 WINDS System Implementation Ministry of Disaster Management came in to agreement with JAXA to implement Sentinel Asia Step 02 enabling WINDS antenna installation and DMC premises, February 2011

21 Capacity Building Program 2010 Disaster Management Centre has organized Sentinel Asia International Capacity Building Program on February, A total of 33 participants including 19 international participants from 11 countries participated

22 Conclusion Lessons learned that the emergency observation can be requested in obtaining near real time images within 48 hours and was able to utilize processed map products for emergency observation Develop capacity of DAN in DMC is necessary in processing satellite data and prepare map products Radar observation is necessary in Sri Lanka as most of the disasters in Sri Lanka are hydrometeorological disasters, where thick clouds disturb optical photography Build capacity of relevant emergency manager s in the use of space technology and map products for disaster management, thereby facilitating in the effective emergency management. Use of WINDS system should be reviewed as the data transmission is not successful due to disturbances. Also it is necessary to review utilization of Regional Server with more useful information products with less disturbances. Emergency observations are mostly useful for floods as wide coverage can be detected easily. However, landslides in Sri Lanka are not big enough to detect by satellite. Develop effective drought monitoring through Sentinel Asia is proposed as future action.
