Paper Abstract
For the flooding seasons of 2011-2012 multiple space assets were used in a "sensorweb" to track major flooding in
Thailand. Worldview-2 multispectral data was used in this effort and provided extremely high spatial resolution (2m /
pixel) multispectral (8 bands at 0.45-1.05 μ m spectra) data from which mostly automated workflows derived surface
water extent and volumetric water information for use by a range of NGO and national authorities. We first describe
how Worldview-2 and its data was integrated into the overall flood tracking sensorweb. We next describe the use of
Support Vector Machine learning techniques that were used to derive surface water extent classifiers. Then we describe
the fusion of surface water extent and digital elevation map (DEM) data to derive volumetric water calculations. Finally
we discuss key future work such as speeding up the workflows and automating the data registration process (the only
portion of the workflow requiring human input).
