Disaster Management and Monitoring 

● Daily regional fire­monitoring using high­resolution SPOT satellite imagery (since 1998).

● Timely high­resolution images (SPOT5, IKONOS) of natural disasters, e.g.

– Indian Ocean Tsunami (Dec 2004)

– Java Earthquake (May 2006)

– Tropical Cyclone Nargis (May 2008), etc.

● Satellite images of disaster­affected areas posted on CRISP website (http://www.crisp.nus.edu.sg)

– linked from the Sentinel Asia website.

Disaster Management and Monitoring● Data Provider for Sentinel Asia:

– Terra and Aqua MODIS hotspots pushed to FTP server; combined with hotspots from other sources and displayed on Sentinel Asia Wildfire webpage

– Web GIS service on CRISP website

– Email alerts to subscribers (and SA Wildfire Workgroup)

– Updated in near­real time

● Research activities and data analysis:

– Coastal changes caused by 2004 tsunami and earthquake

– Biomass burning and aerosol & air quality research

– Environmental monitoring, including water quality and land cover studies

Monitoring of Biomass Burningin Insular Southeast Asia

● Vegetation fires are a yearly occurrence in Southeast Asia.

● The vast majority are man­made, primarily for land­clearing.

● Cause for concern: transition of ENSO from La Niña to El Niño weather conditions.

● Past 2 years: La Niña and positive IOD phase (in 2007) resulted in cloudier conditions with higher rainfall in the insular Southeast Asia region.

● We can expect drier weather to increase the danger of vegetation fires burning out of control this year and the next.

● Real test of fire mitigation efforts in the coming El Niño period.

IKONOS Fire Example 

● IKONOS is not used for regular fire­monitoring, but fires may occasionally be captured.

● The following image in Riau, Sumatra, was received and processed on 19th June 2009. The display is in true­colour, with the full resolution at 1m (pan­sharpened).

Situ Gintung Dam Burst

● The Situ Gintung Dam in Tangerang District in Java, Indonesia (20km west of Jakarta) failed catastrophically on 27th March 2009, resulting in floods which killed at least 100 people.

● The following IKONOS images were acquired on 12th September 2007 and 28th March 2009.

GeoEye­1 example

● GeoEye­1, the newest satellite to be received at the CRISP ground station, has an even higher spatial resolution of 0.5m, compared to IKONOS at 1m.

500m resolution Land Cover Mapof Insular Southeast Asia

● Relatively high resolution and up­to­date land cover map of a region that is currently experiencing rapid change.

● Takes into account the special features of insular Southeast Asia in both data processing and in the actual classification scheme.

● Classification was carried out on a composite of the region generated from 250 Terra MODIS images (MOD09 land surface reflectance product) from Jan­Jul 2007.

● 20 SPOT scenes were used for accuracy assessment, giving an 82% accuracy estimate.

500m resolution Land Cover Mapof Insular Southeast Asia

● Land cover maps like this may be useful for analyses of biomass burning and even large­scale floods.
