HAITI : IDENTIFICATION of the EFFECTS
of the Tropical STORM "JEANNE" in September 2004

The area extends over 28.5 x 30.0 kilometers.

This damage assessment map (processing by ParBleu Technologies Inc.) is produced by superimposition of the temporal changes detected in RADARSAT-1 imagery (16 July 2003 used as a reference, 24 September 2004, and 30 September 2004) on top of a LANDSAT-7 panchromatic image dated 3rd July 2003.
Hence, the colours correspond to changes observed by RADARSAT-1, whereas the LANDSAT-7 image is used as a background map. As a consequence, the locations where no significant changes were detected appear in grey tones.

It is noteworthy that the changes detected over extended areas correspond often to potential damage to vegetation and crop cultivations (characterized by their geometrical shape).

This map is produced in cartographic projection UTM (Universal Transverse Mercator) Zone 18 Q, with Earth ellipsoid WGS 1984 (GPS).

UTM Coordinates :
Upper Left Corner : Northing 2193728, Easting 677035
Lower Right Corner : Northing 2163728, Easting 705535

The spatial resolution is 15.0 meters x 15.0 meters.

Interpretation keys :

Blue tones Areas that became flooded or water-saturated
in the period between the 24th and the 30th of September.

Red tones Areas that were either flooded, or water-saturated
on September 24th, and drained on September 30th (flood recession).

Violet & pink tones Areas that were either flooded or water-saturated
during the whole period of the observations (24-30 September).

Green tones Sedimentation areas and mud deposits.
Grey tones No significant effects.
