Abstract: 

Land is one of the important natural resources. A cities growth is measured not only by population but its spatial dimension. The growth of rural areas has resulted in sharp land use and land cover changes. In recent years, the significance of spatial data technologies, especially the application of remotely sensed and geographical information systems (GIS) has been widely used. The present study investigates the land use and land cover of Gajapati district, Odisha using Landsat satellite images for the year 1995, 2005& 2015. Supervised classification method is used to classify the different classes under the study area. The current study mainly focuses on built-up area in Gajapati district which reveals its expansion by more than fifty percent over the study period. A significant decrease was observed in vegetation areas, agricultural land and open fields of about thirty eight and thirteen percent respectively.
