SeaDAS - SeaWiFS Data Analysis System
Entry ID: SeaDAS

[ Get Service ]
[ Update this Record ]

Abstract: The SeaWiFS Data Analysis System (SeaDAS) is a comprehensive image analysis package for the processing, display, analysis, and quality control of ocean color data. While originally developed to support the SeaWiFS mission, it now supports most US and international ocean color missions. The primary focus of SeaDAS is ocean color data, but it is applicable to many satellite-based earth science data analyses. The latest version (SeaDAS 7.1) is the result of a collaboration with the developers of ESA's BEAM software package. The core visualization package for SeaDAS 7 is based on the BEAM framework, with extensions that provide the functionality provided by previous versions of SeaDAS..

Access Constraints SeaDAS is available for download via anonymous FTP from To connect to the SeaDAS ftp site and download the files, click here. The /seadas directory contains the following compressed tar files. The completed SeaDAS installation will require about 330MB without demo files and 950 MB with demo files. Using the embedded IDL runtime feature will add an additional 130MB to the installation.
Use Constraints SeaDAS is currently available for Linux Mac OS X (Intel and PowerPC), and also runs as a Vmware virtual appliance on Windows platforms. The SeaDAS source code is publicly available, and if any group is interested in porting SeaDAS to another platform, the development team will be happy to give any kind of assistance possible.
