| Abstract | This article presents a new approach based on an integration of multi-attributes semantic partitions (MASP) coming from the three following attributes: an urban growth layer computed from a couple of ERS-SAR images -exploited as a vulnerability map-, a dispersion flow (DF) layer estimated from a linear DF model -used as a flood hazard map-, and a NDVI layer used as an urban/non-urban interpretation measure, in order to produce a flood risk (FR) map. Thus, input mono-attribute semantic partitions (imASP) are first defined from attributes, and their membership degree functions are built based on the fuzzy subset theory. Then imASP are selected to form MASP according to the degree of confidence given to each one to perform the flood risk (FR) and membership degrees of MASP are calculated to provide individual degrees of FR worsening (FRW). Lastly, the global degree of FRWis computed by aggregating previous individual degrees of MASP by using a fuzzy integral (FI) to achieve the resulting FR map. |

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.
