| Abstract | A novel model for measuring the target's slop based on the raw data of full-waveform topographic lidar is proposed. We discussed the range resolution of full-waveform topographic lidar was limited by several key parameters, including the sampling period, laser pulse width and the time period of sub-waveform. A physical model was established to calculate the target's slop and the number of the sub-waveform divided within the whole echo by algorithm. When the lidar equation and the backscatter cross-section equation were described by Gaussian functions, the receiver response function can be also described by Gaussian function. Based on geometry relationship, the expressions of the target's slop can be described by the laser's divergence angle and the marked time of the sub-waveform. This work can be used for improving accuracy and range detection and details of target's slop in future. |

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.
