Abstract:
It is an essential requirement to promote offshore fishing activities
systematically to protect the coastal fishery resources, which are in optimal level of
exploitation. One of the alternatives available is to divert coastal fishing effort to
offshore by providing information on offshore fishing grounds and favourable
environmental parameters. Objective of this present study is to implement web GIS
(Geographic Information System) as a supporting tool to transfer the satellite
derived favourable environmental parameters for fish aggregations to the end user.
In this study, satellite data were processed using remote sensing and GIS software
and the web GIS application was developed using open source Map Server,
PostgreSQL, PostGlS and Mapbender software. Four models were developed to
process the raw data and processed data are uploaded weekly to the World Wide
Web to enhance fishing activities. Potential fishing grounds, sea surface temperature
(SST), chlorophyll (<""1-:(Lse),a surface height (SSH), ocean currents, bathymetry,
exclusive economic zone and fishery harbour locations are displayed in the web GIS
interface. Viewing, zooming, panning, distance measuring, displaying coordinates
and attributes and load WMS(Web Map Service) functions are enabled to provide a
dynamic framework to the user,
