Kiyofuji et al. (2000) studied the spatial and temporal distribution of
squid fishing boats using visible images from the Defense Meteorological
Satellite Programs (DMSP) and from the Operational Linescan System (OLS).
The relationship between SST obtained from Advanced Very High Resolution
Radiometer (AVHRR) developed by the National Oceanic and Atmospheric
Administration (NOAA) and fishing boat distribution was also
investigated. The preliminary conclusion was that by applying marine GIS,
visible images using DMSP/OLS could provide both the position where fishing
boats gather and the relationship between fishing boat location and
SSTs
