| Abstract | The Appalachian Trail (AT) is a continuous scenic footpath that stretches 3,400 km from Maine to Georgia. This analysis provides much-needed land cover change information to conservation efforts along the trail corridor. The study area is a 16 km-wide, 1,339,495 ha corridor centered the AT and the five New England states (ME, NH, VT, CT, and MA). Ten circa-1990 and circa-2000 scenes (fixe per date) from NASA's global orthorectified Landsat data set provided cloud-free coverage. Multitemporal (1990/2000) Kauth-Thomas and 1990 single-date Kauth-Thomas transforms served as inputs in a two-tiered unsupervised classification scheme (k-means). Analysts identified a disturbed natural vegetation class that was spatially and spectrally distinct from agricultural crop cycles, drought, and disease. Overall disturbance for New England from 1990-2000 is estimated at 28,383 ha, 2.17% of total corridor land. Preliminary fine resolution disturbance maps and county-level statistics have been useful to both the National Park Service and the Appalachian Trail Council. |

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.
