| Abstract | In the process of airborne SAR image based disaster evaluation, the first step is to complete image rectification, so the image rectification time is the bottleneck of the whole disaster evaluation process. Dynamic GPS data recording instrument positioned on the airborne SAR airplane can record the precise parameters of the SAR such as the velocity, the latitude, the longitude, the elevation and so on. The parameters are the key parameters to determine the relationship between the pixels of the SAR image and the points on the ground in the F. Leberl formula that is the SAR imaging equation. Thus dynamic GPS data can directly transform coordinates of image pixels to geographical coordinates. With the geographical coordinates, we can rectify the airborne SAR image quickly to make preparation for other processing of disaster evaluation. |

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.
