Abstract

The extent of Built-up Area (BUA) is continuously increasing with rapid globalization. Identification of BUA provides vital information required for territorial planning as well as the impact of land cover changes on the environment. Therefore, detection of changes in land cover should be carried out periodically. However, it is difficult to extract built-up areas using satellite images because of the confusion between spectral values with other land cover types. Presently, satellite sensors provide continuous data in multiple spectral channels, which are becoming very useful for monitoring earth surface over large areas. The primary challenge is to accurately retrieve class information from the enormous set of data.
