Investigation of Remote Sensing Imagery for the Philippine Waters

摘要

The long term goal of the project is to enhance our understanding of the oceanographic processes and features arising in and around straits, and improve our capability to predict the spatial and temporal variability of these regions. The principal objective is to characterize the type and distribution (geographic and temporal) of oceanographic signatures visible in remote sensing imagery around the Philippine Archipelago. The effort made use of historical synthetic aperture radar (SAR) and optical imagery to identify the features in the Philippines straits. These data were then combined with data collected in support the field programs undertaken in 2007, 2008 and 2009. Over 150 historical SAR images were obtained from the European Space agency and the Alaska Satellite Facility and were examined for oceanographic features. Feature locations were tagged and input into Google Earth for dissemination among team members and to support the PhilEx cruises. SAR data acquisition planning was done with cruise scientists and CSTARS at the University of Miami for 2008 and 2009. More than 150 images were obtained during the cruise periods and were obtained/analyzed and disseminated in near real time to support the cruise operations. SAR imagery was also converted to wind speed imagery and disseminated for both near real time and post cruise analysis.
