| Abstract | Extensive applications of Zi-Yuan 3 (ZY-3) satellite imagery of China have commenced since its on-orbit test was finished. Most of the data are processed scene by scene with a few ground control points (GCPs) for each scene; this conventional method is mature and widely used all over the world. However, very little work has focused on its application to super large area blocks. This letter aims to study mapping applications without GCPs for a super large area, which is defined as a range of interprovincial or even nationwide areas. The automatic matching and bundle block adjustment (BBA) software developed by our research team are applied to deal with two blocks of ZY-3 three-line camera imagery which covers most of the provinces in eastern China. Our comparison analysis of different data processing methods and the geolocation accuracies of the overlapped areas between adjacent strips are presented in this letter, as well as the possibility of nationwide BBA. The preliminary test results show that multistrip BBA without GCPs can achieve accuracies of about 13-15 m in both planimetry and height, which means that nationwide BBA is considered practical and feasible. |

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.
