The NOAA-AVHRR sea surface temperature (SST) images and their isotherms appliedto the sea-state nowcast/forecast system will be established in this study. Those SSTdata will be transferred and imported into ArcView geographic information system bySQL query of 2D SST numerical databases (including latitude, longitude MCSST).Then the SST data will be re-sampled by the suitable interpolating method to convertto the shape-format and gridding themes (layers). The SST color images and theirisotherms will be achieved in this study. After that the sea-state nowcast/forecast maps,including SST images or isotherms, will be reported by the fax, e-mail and WWWhomepage etc, which will supply more important fishing information to help fishermento find fishing ground more conveniently and quickly.
