Welcome to the web page that dedicated for the ocean color research in Malaysia and Southeast Asian Countries!
MODIS Aqua chlorophyll a images on
January 2005
This
web page is aim to promote the usage of ocean color remote sensing in
Malaysia. We hope to acquire and distribute information about ocean color
research and application in Malaysia and other Southeast Asian countries, and
to assist the researcher who is interested in this field.

Potential Application of Ocean Color Remote Sensing in Malaysia
If you are new to ocean color
The gateway to understand ocean color – Ocean Color Web. Don’t forget to add the site to your Favorite.
Ocean Color Web
http://oceancolor.gsfc.nasa.gov/
I strongly suggest that the new comer to Ocean Color should read the following material from IOCCG
IOCCG Reports and Articles
http://www.ioccg.org/reports_ioccg.html
Following are the ocean color sensor/ projects that have the coverage of Malaysian waters. Information about ocean color sensor can also be accessed through IOCCG web page.

CZCS (NASA)
This is the first ocean color sensor for global observation. It is more to experimental sensor than operational. However, the data gathered from this sensor had provided detail understanding and knowledge on the development of today ocean color remote sensing.

SeaWiFS (NASA)
http://seawifs.gsfc.nasa.gov/SEAWIFS.html
MODIS (NASA)
There are two MODIS sensors, Terra and Aqua. It has been applied widely for atmospheric, land and ocean application. For instance, MODIS Global Fire Monitoring has been used for the forest fire monitoring in South East Asian Region.

Remarks:
Some
ocean color data is limited to AUTHORIZED USER, i.e. SeaWiFS. There are some
application procedures and agreements to be made before you can access to the
data. However, most of the data are available to REGISTERED USER. If you are
interested in using SeaWiFS images, please register as AUTHORIZED USER.

************************************************************************************
For
the end user who want a Kick Start with ocean color data. You should try the
following
Ocean Color Time-Series Online Visualization and Analysis
System!
This system is
based on the GES-DISC Interactive Online Visualization and ANalysis
Infrastructure (Giovanni) which was developed by the GES DISC DAAC to provide
users with an easy-to-use, Web-based interface for the visualization and
analysis of the Earth Science data.
Many thanks to the
Giovanni Team. It really saves me tones of times and resources in getting the
desire data for my research. If you
don’t want to process the ocean color data by yourself, Giovanni will be the
best solution. This tool is a great milestone in the ocean color research and
development.
Hey, Don’t forget
to markup the site too!

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. SeaDAS works on PC with LINUX OS. The user must have minimum
knowledge in UNIX OS for the software installation. The latest version of SeaDAS
is capable for MODIS image processing.

MODIS
and GIS
Please
check the following page if you are interested to input your MODIS images
into GIS.
MODIS
GIS User Guide
http://daac.gsfc.nasa.gov/MODIS/GIS/index.shtml
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.
HDFLook

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.
