McLaren, David; Doubleday, Joshua; Chien, Steve, 2012, "Using WorldView-2 imagery to track flooding in Thailand in a multi-asset sensorweb", https://hdl.handle.net/2014/42594, SPIE Algorithms and technologies for multispectral, hyperspectral, and ultraspectral imagery XVIII : Baltimore, Maryland, April 23-27, 2012, JPL Open Repository
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 s... |
