The SeaWiFS ocean colour sensor on board the SeaStar (Orbview 2) satellite is able to derive the chlorophyll concentration in the surface sea water. The chlorophyll algorithm employed is based on the ratio of radiance or reflectance measured in the blue and green spectral bands. Regression between the band ratio and the in-situ measurements of chlorophyll(More)
* Corresponding author. Abstract – The Worldview-2 satellite imagery with 2-m spatial resolution and 8 spectral bands is used to map the coastal ecosystems for our study site, an offshore island of Singapore. The eastern side of the study area is used as a landfill, while the western part of the island is left natural with rich biodiversity where large(More)
Stereophotogrammetry, using an overlapping stereo pair of images, has been a major tool for generating the 3-D information of buildings in earth maps. With the stereoscopy, a 3-D stereo model is formed in the brain of human operator by the process of binocular vision. The 3-D depth of the building of interest is perceived using two fundamental cues: double(More)
Recently global climate change has been a great environmental concern in many countries. Most of the populations in the Southeast Asia region reside in coastal zones, which will be affected by sea level rise due to climate change. Change in precipitation, land and sea surface temperature and cloud cover will have effects on agriculture, forest vegetation,(More)
