n all of the cities it can be identified that the higher densities are concentrated in the city centres and the expansion is taken place along the roads. The expansion pattern is shaped by the geography of the surrounding area. The selection of the area for the urban expansion analysis was followed by several preliminary studies. Initially, the urban index values which was identified using the remote sensing information were studied in the respective municipal areas including a fringe area. Before selecting interested area for the expansion analysis it should consider following facts – Municipal boundary – At least 2-3 km buffer around Municipal boundary – Rough boundary where the physical urban character disappearing In the remote sensing discipline, the values higher than 0 represent the built-up areas.The boundary for the fringe area was identified by getting the extent of urban expansion as well as a fine boundary where the high-density expansion become insignificant. The identified boundaries were projected on to the latest satellite images to assure the identified urban index values are in line with the existing building densities.
