| Abstract | Effective use of remotely sensed data requires a conceptual understanding or model of the attributes of that environment that control the reflection, absorption and transmission of electromagnetic radiation (EMR). This model needs to be developed at a number of spatial scales and for imagery acquired from various regions of the electromagnetic spectrum. Coral reefs have, as yet, not been studied in this way. A complicating factor is that spatial variations of water depth and water quality prevent normalisation of image data to allow accurate mapping, estimation of biophysical properties and change detection. Another factor is the geometry and scale of reef feature variation, especially in relation to the vertical orientation and location of photosynthetic and productive components. The aim of this paper is to present a conceptual model for extracting multi-temporal biophysical information from remotely sensed data of coral reefs. The model is applicable from the scale of micro-algae and polyps, to individual coral heads, reefs and reef ecosystems, and is intended to provide a basis for 'scaling-up' fine scale measurements to cover larger areas and longer time periods. Model development and testing involved reviews of relevant literature coupled with field spectrometer and pulse amplitude modulated (PAM) fluorometer data, airborne multispectral and hyperspectral image data, and satellite multispectral data from the Great Barrier Reef (GBR), Australia. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
