| Abstract | In this paper, an object oriented approach for automatic building extraction from high resolution satellite image is developed. Firstly, Single Feature Classification is applied on the high resolution satellite image. After that, the high resolution image is segmented by using the split and merge segmentation so that the pixels that are grouped as raster objects have probability attributes associated with them. Then different filters are applied on the image to remove the objects which are not of our interest. After filtering the segments, the output raster image is converted into vector image. After converting the raster image into vector image, the building objects are extracted on the basis of area. The cleanup methods are applied to smoothen the extracted buildings and also to increase the accuracy of extraction of buildings. Imagine Objective tool of ERDAS 2011 has been used. The approach is applied on three different satellite images. The extracted buildings are compared with the manually digitized buildings. For one satellite image it has picked up all the buildings with a slight change in the area of footprints of buildings. Only one patch of road is extracted as a building. For the other two satellite images, the overall accuracy is low as compared to the first satellite image. Some patches of road and ground are also extracted as buildings. The branching factor, miss factor, building detection percentage and quality percentage were also calculated for accuracy assessment. Nonetheless, the overall accuracy of building extraction with respect to area was found to be 85.38% in a set of 66 buildings, 73.81% in a set of 94 buildings and 70.64% in a set of 102 buildings. |

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.
