Abstract
This study aims mainly to establish appropriate evaluation method and system for Terra/MODIS and Aqua/MODIS data to monitor corresponding macroscopic ocean environment. To obtain accurate results of ocean color or water quality, especially Chlorophyll-a, using these satellite data, establishment and install of specific radiometric correctional algorithm and a proven empirical algorithm into our system. As results : 1) two algorithms to convert or correct satellite original set radiometrically and geographically were created and proven, 2) a new image processing system that can effectively cope with archiving large quantities of time-series chlorophyll-a concentration data using Terra-Aqua/MODIS data for monitoring adjacent water area surrounding this country has been established successfully.
