Cropped ZKI Crisis mapWhen a disaster occurs, rapid mapping activities using satellite data can provide valuable information to support emergency response actions. Such was the case recently when severe earthquake and tsunami events hit Sumatra, prompting the contribution from the Center for Satellite Based Crisis Information, a service of the German Aerospace Center (DLR).

Normalized Digitized Vegetation Index image for portion of Tyrrell County showing green color as least vegetated; grey as greatest, red colors indicate intermediate levels of chlorophyll and Gold-colored outlines show NCDCM locations of wetlands.This article focuses on a NASA Applied Sciences National DEVELOP assistance to the North Carolina Division of Coastal Management (NCDCM) with the assessment of coastline changes and habitat loss in coastal wetlands utilizing satellite remote sensing. The Hyde, Tyrrell, and Dare counties in eastern North Carolina occupy the coastlines of the Albemarle and Pamlico Sound estuaries. The Pamlico Sound is the largest estuarine lagoon along the East coast of the United States.

It highlights some image maps and information products that were produced as part of several trials during the 2010 hurricane season. From this trial phase, the participants expect constructive feedback and further improvements, particularly with regard to operational usefulness of detailed EO satellite data.
