| Abstract | Crofton weed (Eupatorium adenophorum spreng) is an invasive species widely distributed in southwest of China. In this paper, we proposed a method for mapping the distribution of Crofton weed using time series remote sensing data. Because the reflectance signatures of the white flowers of Crofton weed are quite different from the other green components of plants, dissimilar index and flower index can be applied to map the abundance of the weed. In this study, we proposed a Crofton weed index (CWI) to map the intensity and extent of Crofton weed. The MODIS, AVHRR NDVI data and HJ satellite data are employed as the time series remote sensing data. The distribution map developed by this algorithm shows the extent and density of the invasive species in southwest of China. It was also validated with high resolution remote sensing data and ground survey maps. The comparison results show that this method is accurate and particular useful for mapping invasive species. |

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.
