| Abstract | Oasis cities are the special regions in arid zones, which have the densest human activities and the most sensitive relationship between human and natural environment. Rapid urbanization of oasis cities of Xinjiang, China has impacted on the stability and economic sustainable development of the region during the past decade. Therefore, monitoring urban spatial growth and land cover change brought on by urbanization has been a critical concern to urban land management decision-making, ecosystem monitoring, and urban planning. In this research, we investigate the usefulness of satellite-derived imperviousness as an alternative for urban spatial growth characterization. The research consists of two procedures. Firstly, this study explored extraction of impervious surface information from Landsat TM data in 1987 and 2007 acquired over Urumqi, Xinjiang with the integration of fraction images from linear spectral mixture analysis based upon Ridd's vegetation-impervious surface-soil (V-I-S) model. Accuracy assessment indicated that the mean RMS errors are less than 0.02. Secondly, we analyzed the spatio-temporal changing trend of imperviousness with the visual inspection and emphasis upon some “hot” spots of development areas. We conclude that satellite-derived imperviousness is able to serve as a timely and cost-effective manner for objective assessment of the oasis urban spatial growth in arid region. |

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.
