| Abstract | This paper presents an overview of the use of lineaments in landslide hazard mapping. The lineaments are normally derived either from aerial photographs or satellite imagery. The relative advantages and disadvantages of digital image processing and manual (visual) lineament interpretation are discussed. Most researchers prefer the manual technique, despite the fact it is more time-consuming and subjective, as it allows a higher degree of operator control. Ways of increasing objectivity in the interpretation are suggested. It is hoped that lineament mapping will increasingly be incorporated in landslide hazard assessment hence the paper emphasizes the need for care and a proper understanding of these methods and their limitations.L’article présente une revue sur l’utilisation des linéaments pour la cartographie de l’aléa de glissement de terrain. Les linéaments sont normalement obtenus à partir de photographies aériennes ou d’images satellitaires. Les avantages et inconvénients des traitements numériques des images et des interprétations manuelles (visuelles) des linéaments sont discutés. La plupart des chercheurs préfèrent les techniques manuelles, malgré le fait qu’elles sont longues et subjectives, considérant qu’elles permettent un meilleur contrôle par l’opérateur. Des moyens d’améliorer l’objectivité dans l’interprétation sont suggérés. On peut espérer que la cartographie de linéaments sera incorporée de façon plus importante dans l’évaluation des aléas de glissement de terrain. C’est pourquoi l’article met l’accent sur la nécessité de bien maîtriser ces méthodes et connaître leurs limites. |

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.
