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.

If you are new to ocean color

 

The gateway to understand ocean color Ė Ocean Color Web. Donít forget to add the site to your Favorite.

 

Ocean Color Web

I strongly suggest that the new comer to Ocean Color should read the following material from IOCCG

 

IOCCG Reports and Articles

Ocean Color Sensor/ Project

 

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.

 

http://www.ioccg.org/sensors_ioccg.html

 

 

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.

 

OCTS (JAPAN)

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.

Ocean Color Data Access

 

Both SeaWiFS and MODIS Aqua images are available on Ocean Color Web

 

Level 1 and 2 Data Browser

http://oceancolor.gsfc.nasa.gov/cgi/browse.pl?sen=am

 

Level 3 Data Browser

http://oceancolor.gsfc.nasa.gov/cgi/level3.pl

 

 

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.

 

 

MODIS Ocean Color Images of Northern Borneo

 

The following link will open the ftp site that providing Daily MODIS Aqua chlorophyll a, nLw 551, and SST images for the area around northern Borneo Island. This automated service is kindly provided by Ocean Color Web.

************************************************************************************

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 donít 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, Donít 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

http://www-loa.univ-lille1.fr/Hdflook/hdflook_gb.html

 

 

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.
