Flood Waters in Batticaloa District, Sri Lanka
	International Charter Space and Major Disasters Product ID: 1405 - 24 Dec, 2009 - English GLIDE: FF-2009-000260-LKA Product FOOTPRINT (LAT x LONG, WSG84 Geographic, decimal degrees) TopLeft: 8.041693 x 81.137776 BottomRight: 7.173859 x 81.986218 This map illustrates satellite-detected areas of likely standing flood waters and flood-affected land / saturated soils among the affected towns and villages of Batticaloa District, based on change detection analysis with ENVISAT ASAR IMP radar data recorded 14 December and 9 March 2009. Because the input radar scenes were acquired with VV polarization, there is an associated higher level of uncertainty regarding the accuracy and completeness of water detection. It is possible that water levels have been underestimated in heavily vegetated areas and within urban environments. This flood assessment is a preliminary analysis & has not yet been validated in the field. Please send ground feedback to UNITAR / UNOSAT.

IDP Shelter Assessment for Civilian Safety Zone (CSZ) - Mulattivu District, Sri Lanka
	Product ID: 1341 - 23 Mar, 2009 - English GLIDE: SE-2009-000011-LKA Product FOOTPRINT (LAT x LONG, WSG84 Geographic, decimal degrees) TopLeft: 9.364135 x 80.696231 BottomRight: 9.320138 x 80.78481 A satellite-derived estimate based on automatic detection methods, indicates there are approximately 31,400 buildings / shelters within the CSZ and approximately 800 additional shelters immediately outside the zone as of 6 March 2009. This is an increase of approximately 18,200 from the count estimate of 13,200 on 19 February, and a total increase of over 28,700 from 5 February 2009. Note that the satellite imagery from 6 March 2009 did not cover the southern portion of the CSZ and thus the total shelter count is likely to be higher. The count from 5 February (2,650) represented almost all fixed buildings, and not tent shelters associated with IDP presence. Because of this rapid influx of IDPs, the available land for shelter placement has decreased, forcing thousands of IDPs arriving in late February and early March to locate their tents on marginal lands previously avoided by earlier IDP arrivals in the CSZ. As the three satellite imagery focus maps illustrate below, thousands of IDP shelters have been erected in wetland areas prone to flooding, along the beach within 200m of the coastline as well as on deforested land, recently cleared for new settlement. Analysis was done with WorldView-1 satellite imagery from 5, 18-19 February & QuickBird imagery from 6 March 2009. This is an initial assessment and has not been verified in the field.

Newly Erected IDP Shelters within Civilian Safety Zone (CSZ) - Mulattivu District, Sri Lanka
	Product ID: 1333 - 26 Feb, 2009 - English GLIDE: SE-2009-000011-LKA Product FOOTPRINT (LAT x LONG, WSG84 Geographic, decimal degrees) TopLeft: 9.365736 x 80.701995 BottomRight: 9.298567 x 80.81633 Analysis summary of satellite imagery acquired on 5, 18-19 February 2009 over the government-declared "Civilian Safe Zone" (CSZ) in the Mulattivu district of northern Sri Lanka: There are clear indications that thousands of IDPS have moved into the northern half of the CSZ between 5 & 19 February 2009. A satellite-derived preliminary estimate based on automatic detection methods, indicates there are approximately 2,850 newly erected IDP shelter structures within the area designated PC9. This represents a minimum increase of over 100% from the total building count within CSZ of 2,600 as of 5/2/09. Because of incomplete imagery coverage over northern CSZ, there is a high probability that the IDP structure count is significantly higher. It is important to note that no newly erected IDP shelter structures were detected in the southern half of CSZ. There are several possible impact crater sites within the southern half of the CSZ, along with limited building damages. Analysis was done with WorldView-1 satellite imagery recorded on 5 & 18-19 February 2009 at a spatial resolution of approximately 0.5 meters. This is an initial assessment and has not been verified in the field.
