| Abstract | An approach for analyzing and validating thematic and positional accuracy of high resolution global land cover data set is described. Portions of the International Geosphere/Biosphere Programme's (IGBP) 1 Kilometer Land Cover Data Set are used as a test bed to evaluate procedures for accuracy assessment and validation. The 1 km Land Cover Data Set contains 17 land cover classes ranging from natural vegetation to developed land and non-vegetated classes. This study focuses on developing statistical map accuracy procedures for data set validation through a continental scale cross validation exercise using the 1 km land cover data set. The objective of this exercise is to assess the potential of the IGBP fast track validation procedures. These include implementation of an integrated overall map accuracy analysis as well as a detailed category specific thematic accuracy assessment for both a North American and African study site. Specific goals of this study are to: (1) determine whether different classification techniques employed for Africa and North America significantly affect the classification of the 1 km Land Cover Data Set; (2) determine whether systematic differences are introduced into the datasets by the separate processing flows; (3) examine and attempt to explain any non-systematic differences which may be identified, and; (4) derive a statistical estimate of these differences between the two datasets for each of the 17 Land Cover classes-or as many of the classes as are adequately represented. |

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.
