| Abstract | A novel method to extract DEM based on IKONOS stereo-pairs is proposed. And its accuracy is assessed adopting checkpoint, profile and image analysis methods, respectively. Results show that the changes of elevation and image color of extracted DEM are basically agreement with the topographic map, but the latter has significantly detailed feature; the error in areas of larger terrain fluctuation is bigger than that in flat areas. It is not only fast and efficient to extract DEM based on IKONOS stereo-pairs, but also applicable to a wide range, which can meet some specific needs. |

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.
