| Abstract | 3D urban geological modeling is an important research issue with the studying of the digital city in China. In view of the deficiencies of present modeling methods, a new method to model 3D urban geological body including faults based on generalized tri-prism (GTP) model is presented. Four geological knowledge inference rules about urban 3D urban geological modeling are put forward. The method mainly includes three steps: (a) Process and organize the borehole data; (b) Generate Delaunay TIN (D-TIN) of the geological upper surface according to borehole's collar data; (c) Extend each triangle of the D-TINs down into GTP along borehole line referring to the four geological knowledge inference rules. In order to improve the flexibility and the interactivity of 3D visualization, a 3D interactive environment is provided. The application for 3D geosciences modeling and 3D visualization including 3D interactive visualization, aided design and spatial inquiry etc are introduced. A real-3D geosciences modeling system, GeoMo3D, is developed with VC++, OpenGL and SQL sever. An actual 3D geological model of an exploring district of University City, Guangzhou, is shown as a case. |

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.
