| Abstract | At present, a great deal of western area in China has still lacked of corresponding relief maps. Because of the cloudy or soupy mountainous conditions in these districts, the high resolution airborne SAR imagery has often been chose as the irreplaceable data resource, while remote sensing cartography technique is being performed. At the same time, the mission that how to acquire enough accuracy and quantity of ground control points (GCPs), which are difficult to be measured in practical, has become an urgent demand for mapping tasks. This work analyzes the practical conditions, and divides it into two instances, that is, which with and without navigation data provided from GPS/INS system. It discusses the aerial triangulation theory from airborne SAR images, with which only sparse GCPs around the mapping area could be provided, puts forward the corresponding mathematical model, and sequent technique flow, according of which we can obtain the coordinates of the required GCPs for cartography. Lastly, the airborne SAR imagery of 1m-resolution, in the area of Zhengzhou, in China, has been taken as an experiment data to validate the model, and a corresponding accuracy analysis derived from the developed software has been presented. |

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.
