SeaDAS Visualization Installers

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]_installer.sh

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.

Currently, the processing components can only be installed on Linux or MacOSX (Intel, not PowerPC) systems. The Linux binaries were compiled on a system with GLIBC-2.14. If your system has an older version, you will need to build the binaries from source.

Processing Component Sizes

A typical installation (e.g. processing programs, MODIS and SeaWiFS data files) will require 3 — 5G of disk space. A full installation will require more than 10G of disk space.

• Size is for a single MODIS sensor. If both are selected, the combined total would be 1.3G, as some components are shared between the MODIS-Aqua and MODIS-Terra sensors.

Install with GUI

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

• Select the menu item DataProcessing → 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
• Bash
• Python
• Git
• cURL
2. Download the installer script
3. Make sure the installer script is executable:

    $ chmod +x install_ocssw.py
    

4. Run the installer:
The following will install the processing programs and required data packages for the MODIS-Aqua and SeaWiFS missions into the user's HOME directory:

    $ ./install_ocssw.py --install-dir=$HOME/ocssw --git-branch=<version> --aqua --seawifs 

* Replace <version> in the --git-branch option with the desired branch. (e.g.--git-branch=v7.2) * The following will install the processing source code into an existing directory:

    $ ./install_ocssw.py --install-dir=$HOME/ocssw --git-branch=<version> --src

The following will install the programs and data packages required for MODIS direct broadcast processing:

    $ ./install_ocssw.py --install-dir=$HOME/ocssw --direct-broadcast

Command Line Configuration

Add the following lines to your “.bashrc” file to configure your command line environment. This assumes your login shell is bash. If you are using a different shell, talk to your system admin.

export OCSSWROOT=[SeaDAS_install_dir]/ocssw
source $OCSSWROOT/OCSSW_bash.env

where: [SeaDAS_install_dir] is the directory where you installed SeaDAS.
