| Abstract | In this paper, the impacts of the random measurement errors on airborne laser scanning (ALS) accuracy were studied. Firstly, the transformation formulas from measurement parameters to the coordinates of laser footprints were derived and the factors affecting ALS accuracy were analyzed. According to the actual characteristics of these factors, 2000 sets of experimental data of the random measurement errors were simulated and the errors of three-dimensional (3D) coordinates of the laser footprints were calculated. Then, the simulated experimental error data were processed by using the linear least squares regression method to get the standardized regression coefficients. According to the obtained standardized regression coefficients, the impacts of various random measurement errors on the 3D coordinate errors were evaluated quantitatively, and the variation of the impacts with increasing flight height was studied. Analysis results provide an important basis for error budget of ALS system and improvement of ALS accuracy. |

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.
