Monitoring the Recovery Process of the Disaster-Affected Areas -Scaling Context Image Analysis in GEO Grid-Based Solution
2008 (English)In: INTERNATIONAL ARCHIVES OF PHOTOGRAMMETRY REMOTE SENSING AND SPATIAL INFORMATION SCIENCES, Elsevier, 2008, Vol. 11, no 4, 1625-1630 p.Conference paper (Refereed)
This paper presents a new remotely sensed solution for monitoring the recovery of a large disaster-affected area. It exploits thepowerful data grid and computing grid technologies developed on GEO (Global Earth Observation) Grid system. Accessing theASTER portal site of GEO Grid, all the necessary ASTER multi-spectral images and on-demand ASTER digital elevation model(DEM) are easily and quickly collected. Subsequently, satellite images are automatically analyzed on a grid-based computingmechanism. The core processing is a newly developed context-based mapping approach named scaling context image analysis.Phanga province of Thailand, which was strongly attacked by the 2004 Indian Ocean tsunami, is selected as the demonstration site.Four ASTER data sets acquired on November 15, 2002 (pre-event); December 31, 2004 (just after-event); February 8, 2005 andJanuary 26, 2006 (post-event) are used. The efficiency in data collection and data computation is the merit of the proposed solution.
