Abstract
Remote sensing studies have shown that urban areas have unique environmental, climatic, land use/cover characteristics as a result of intense anthropogenic activities. Consequently, urban areas have developed distinct micro-climate and elevated temperatures. Thermal remote sensing data has been widely used to study these characteristics. In this study, an attempt has been made to review the studies involving Landsat remote sensing dataset for investigating land surface temperature. Landsat is oldest finer resolution thermal dataset, which has been effectively used in mapping and analysis of land surface temperature, urban heat island and urban micro-climate. Since 1978, it has been providing thermal data through Thematic Mapper (TM), Enhanced Thematic Mapper Plus (ETM+) and Thermal Infrared Sensor (TIRS) sensors.
Keywords: land surface temperature, urbanisation, Landsat thermal data, surface urban heat island

Abstract
Geography studies the characteristics of space and place. Geography answers questions such as where things, activities or phenomena are located, why they are located there, how the features and activities interact, and what factors cause this distribution. An ideal geographer exercises both scientific and social analytical skills. Geography has been called a bridge between human and physical sciences. In the beginning, geography focussed on the physical aspects of the earth but modern geography is an all-encompassing discipline that seeks to understand the earth and all of its human and natural complexities as an integrating science. The paper deals with changing professional avenues for geographers, the role of geography towards the future earth and human geosciences together with the role the IGU can play in the Future of World Geography.
