| Abstract | A task fundamental to advancing global change research is the availability of a standard reference system for direct digital comparison and interuse of remote sensing data sets on varying spatial and temporal scales. The availability of a standard gridding scheme is an essential requirement for systematic time-series studies. Such a scheme also supports the direct comparison of different remote sensing products, as well as the validation of algorithms, through digital comparison with surface station and other ancillary data sets which have been processed into the common grid. New software now allows users of Special Sensor Microwave/Imager (SSM/I) data to produce their own Equal-Area Scalable Earth Grid (EASE-Grid) image data from Temperature Data Record (TDR) format swath data. Overlapping orbit data are separately retained for the highest possible temporal resolution, and data for specific pixels can be extracted. The modular processor also simplifies testing of alternative resampling and gridding algorithms. The EASE-Grid is a standard gridding scheme now used with a variety of satellite datasets, including SSM/I data, its original application. Although the specific method used to interpolate from native sensor coordinates to a fixed Earth grid is unique to each sensor, the fundamental projection and gridding concept of the EASE-Grid provides the basis for a standard interuse gridding method. Thus, the SSM/I EASE-Grid is composed of two fundamental parts: i) a grid and projection scheme and, 2) a specific method to interpolate SSM/I data from swath space to Earth gridded coordinates. The projection and gridding scheme is independent of the satellite sensor or data type. |

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.
