The Development of a WISP Information System.
Abstract
A data handling system was developed for WISP data. The procedure for the reduction of the raw flight data to graphic displays were refined in the program. Computed-generated maps are presented which enhance the various scene features and these are based upon the selection of the appropriate algorithms to fit the scene information. Polarization measurements of the airlight directed upward over the oceans were obtained up to 10,000 feet altitudes. The high values of polarization obtained suggest a significant gain in signal contrast will result from use of polarizers in spacecraft ocean color sensors. Low altitude spectrometer flights over sewage outfalls and 'red tide' resulted in good correlation between the visible spectral nature of the upwelling light and ground truth turbidity and organism counts. Useful algorithms were developed to best characterize the nature of the spectral data and the existing types of water pollution. Spectrometer measurements of a deliberate oil spillage on the ocean indicated no visible signatures were present. (Author)
