In some browsers you may need to right click on the appropriate link and choose “Save Link As” to download the installer.

The Windows installers are executables. The MacOSX installer is a dmg file. The Linux installers are shell scripts. They can be executed as the following:

        $ sh seadas_<version>_linux[64]

Once installed, you may wish to add the seadas-<version>/bin directory to your path to allow easy launching of SeaDAS, e.g. add the following to your .bashrc:

        $ export PATH=[full-path-to]/seadas-<version>/bin:$PATH

SeaDAS Processing Programs and Source Code

The SeaDAS data processing components are distributed separately from the SeaDAS visualization package.

SeaDAS now supports a client/server model for accessing the processing components from the SeaDAS visualization package.

Currently, the processing components can only be installed on Linux or MacOSX (Intel) systems. The Linux binaries were compiled on a system with Ubuntu 16.04 and gcc-4.8. If your system is not the same, you might need to build the binaries from source.

Install with GUI

Once the visualization package is installed, you can easily install the processing components:

  • Select the menu item OCSSW → Install OC Processors

  • Select desired options and click Run*
  • Once installed, the processing components can be updated when necessary by repeating the above steps. The menu item will have changed from Install OC Processors to Update OC Processors

Manual Installation

The processing components can be installed manually, with or without the installation of the visualization package.

  1. Ensure that the requirements are satisfied
  2. Download the installer script
  3. Make sure the installer script is executable:
  4.     $ chmod +x
  5. Run the installer:
  6. The following will install the processing programs and required data packages for the MODIS-Aqua and SeaWiFS missions into the user's HOME directory (in the --git-branch option replace <version> with the desired branch. (e.g.--git-branch=v7.5):
        $ ./ --install-dir=$HOME/ocssw --git-branch=<version> --aqua --seawifs 
    The following will install the processing source code into an existing directory:
        $ ./ --install-dir=$HOME/ocssw --git-branch=<version> --src
    The following will install the programs and data packages required for MODIS direct broadcast processing:
        $ ./ --install-dir=$HOME/ocssw --direct-broadcast --git-branch=<version>
Note: this includes the processing programs and the MODIS-Aqua and MODIS-Terra data packages. It does NOT include the source code.
