| Abstract | Based on the concept of fuzzy logic, a new map-matching algorithm was proposed to reduce the GPS positioning error by means of position correction in use of the digital map. Firstly, three fuzzy rules are introduced in different aspects which may influent the credibility judgment of the best matching road. And the corresponding membership functions are defined in details separately for sub-evaluations of the direction consistency, the proximity and the track similarity against the original GPS position and its candidate road, where dead reckoning technique is referred. Secondly, the comprehensive evaluation performing as the unique basis for final judgment is made by doing simple addition of the results of these sub-evaluations with certain weights according to their contributions towards the credibility judgment. Finally, the original GPS position is revised by making a vertical projection onto the best matching road. Experimental results demonstrate the effectiveness and applicability of this algorithm in improving the GPS positioning 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.
