Ocean Color Processing Software


Most of the commercial software are unable to process and analyze ocean color data effectively. If you intend to use SeaWiFS data, the best recommendation is SeaDAS. The SeaWiFS Data Analysis System (SeaDAS) is a comprehensive image analysis package for the processing, display, analysis, and quality control of ocean color data. The latest version (SeaDAS 7) is the result of a collaboration with the developers of ESA’s BEAM software package. SeaDAS 7.0 is currently available for Linux, Mac OS X, and Windows. The Windows version currently does not support the science data processing code. The SeaDAS source code is publicly available.

BEAM is an open-source toolbox and development platform for viewing, analysing and processing of remote sensing raster data. Originally developed to facilitate the utilisation of image data from Envisat’s optical instruments, BEAM now supports a growing number of other raster data formats such as GeoTIFF and NetCDF as well as data formats of other EO sensors such as MODIS, AVHRR, AVNIR, PRISM and CHRIS/Proba. Various data and algorithms are supported by dedicated extension plug-ins.



WIM is a general-purpose image display and analysis program for the Microsoft Windows operating systems with special features for analyzing satellite images. It is not a freeware, where license need to be purchased.



Please check the following page if you are interested to input your MODIS images into GIS.

MODIS GIS User Guide

For the processing of higher resolution images, like 500m or 250m. The following software is capable to process the 250m & 500m RGB images if you have the proper type of MODIS images downloaded.

HDFLook is capable to generate the 250m RGB images for both MODIS Terra and Aqua images. The output can be in JPEG or GeoTiff. With the Geotiff image, you can input the image directly into the GIS software such as ArcGIS. This software can be install on various platform. However, for installation in WinXP, you will need to pre-install Cygwin with Xterm on your computer.

The HDF-EOS To GeoTIFF Conversion Tool (HEG) is a tool developed to allow a user to reformat, re-project and perform stitching/mosaicing and subsetting operations on HDF-EOS objects. The output GeoTIFF file is ingestible into commonly used GIS applications. HEG will also write to HDF-EOS Grid & SWATH formats (i.e for Subsetting purposes) and native (or raw) binary. HEG presently works with MODIS (AQUA and TERRA), ASTER, MISR, AIRS, and AMSR-E HDF-EOS data sets.
