| Abstract | Describes a computer-aided geological interpretation system developed for radio attenuation tomographic imaging of subsurface geology with immediate application in mining geophysics. Measurements in remote sensing are often expensive so that, in practice, the data-interpretation process is plagued by insufficient data. Inverse procedures are generally ill-posed leading to the use of regularization techniques which are mathematically tractable but rarely physically relevant to the problem. The authors' response to this has been to invert the normal imaging philosophy. Instead of using the data to reconstruct an image for interpretation by some domain expert, they provide a computational system in which set theoretic techniques are used to modify hypotheses provided by the expert in image form to make them consistent with the data and other constraints. This is an implementation of the hypothetico-deductive model of scientific method. While the actual image-processing algorithms such as tomographic inversion are based on sophisticated techniques, the authors have made a considerable effort to remove this level of abstraction for the benefit of geologists and geophysicists who are the target users. By employing X-Windows-based, graphical user interface methods, in conjunction with graphics and image-based visualization, the system can be used intuitively to explore the possibilities offered by the data without an extensive knowledge of the processing techniques. The application of the system to field examples from the Australian mining industry is shown in the interactive presentation. |

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.
