Development of Spectral Library of Mangroves, Seagrass and Seaweed
The Project
Spectral signature, the unique variations of reflected electromagnetic radiations as function of wavelengths helps in identifying terrain features and is the fundamental means of data representation and analysis in all forms of passive (reflected sunlight) remote sensing. A spectral library categorizes the spectral reflectance signatures collected using spectroradiometers through a standardized procedure from laboratory or field measurements along with metadata. It helps to characterize the features on earth and its variability and diversity globally. India with a long coastline of about 7500 km bordered by Arabian Sea in the West and Bay of Bengal in the East sustains luxuriant coastal vegetation comprising of mangroves, seagrass, salt marsh and seaweeds.
Aim
Development of spectral library of coastal vegetation and implementation of a consistent method for the collection of spectral data and associated metadata
