| Abstract | This paper introduces the updated plans for sensor calibration and product validation of the two optical sensors i.e., the Panchromatic Remote-sensing Instrument for Stereo Mapping (PRISM) and the Advanced Visible and Near Infrared Radiometer type-2 (AVNIR-2), which are to fly on the Advanced Land Observing Satellite (ALOS). PRISM consists of three panchromatic radiometers, and is used to derive Digital Elevation Models (DEMs) with very high spatial resolution, which is also one of the objectives of the ALOS mission. The geometric calibration is important in generating a highly accurate DEM by using PRISM's triplet images. Highly accurate ground control points (GCPs) are necessary to calibrate the geometric accuracy and validate the generated DEM. The geometric calibration of AVNIR-2 can be done using the calibrated PRISM product. In this paper, we describe the current plans for calibrating and validating PRISM and AVNIR-2. In particular, preparation status of GCPs with evaluation items for geometric calibration, including expected problem effects regarding geometric accuracy, orbit and observation simulations to determine pointing accuracy, and preliminary investigation of nighttime GCP using current available satellite images |

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.
