| Abstract | As a fundamental study of the image database category index, the authors have been analysing the classification of sea and land levels based on the albedo value obtained from NOAA-11 satellite at the area of northern Japan. The target image is NOAA AVHRR CH2 image, which has been studied automatic data analysis of the whole set of data for a period of three years (1990.4/spl sim/1993.3). The authors tried to relate the sea and land level by albedo value with the elevation of Sun when the satellite observed. The classification method is unique technique because of matching the CH2 image with sea and land data, whose data is composed of 0 and 1 values. The authors have shown the change of albedo of the image category corresponding to the seasonal change. Also shown is the classification of sea and land levels (the tangent of time and elevation of Sun) are rising year by year. The authors have proposed the recognition ratio of sea and land as a new key word of NOAA AVHRR CH2 image search index. |

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.
