Abstract | Spatial data mining fulfils the real needs of many geomatic applications. It allows taking advantage of the growing availability of geographically referenced data and their potential richness. This includes the spatial analysis of risk such as epidemic risk or traffic accident risk in the road network. This work deals with the method of decision trees for spatial data classification. This method differs from conventional decision trees by taking account of implicit spatial relationships in addition to other object attributes. Our approach consists in materializing those spatial relationships leading to treat them as normal attributes. Then, any conventional decision tree building method could be applied providing a spatial decision tree. Compared to existent approaches, this one is more flexible because no specific algorithm is imposed. Moreover, it considers the organization in several thematic layers that is characteristic of geographical data by distinguishing the intra theme and the inter theme relations (such as the road section contiguity or the proximity between road sections and schools). This method has been tested in the framework of traffic risk analysis. |

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.
