Land surface temperature (LST) is an important for urban environment. Our research mainly based on the landuse and landcover (LULC) on LST. The research of our study tells how the LST variations based especially for a rapidly developing city such as Vellore, India. This study uses the techniques of remote sensing and geographic information system (GIS) to detect the temperature variation of LST. The spatial variability of texture in LST was done. These variations are also present in the images, and are responsible for the spatial patterns in an urban environment. The result values shows that both the spatial and temporal variation in surface temperature is associated with CO2 concentration levels and thus affects the local land use pattern

Greater Hyderabad a twin city in earlier days, has grown into a tricity of Cyberabad - Hyderabad – Secunderabad. This concentrated development with impetus on industrialization has led to unprecedented urbanization and sprawl, resulting in heavy population growth and ultimately raising serious challenges such as traffic congestion, enhanced Green House Gas (GHG) emissions causing climatic changes apart from over-use of basic amenities and infrastructure. This study shows that urban areas have grown from a mere 172 sq km of MCH (Municipal Corporation of Hyderabad) in the 1970's to a whopping 1905 sq km at present, currently known as the Greater Hyderabad Metropolitan Corporation. The phenomenon of Urban Heat Island (UHI) can be observed in several localities. The pattern of growth of Greater Hyderabad and its repercussions on the local climate are studied with the help of geospatial technologies. An increase of ~20C to 2.50C is observed over the last 2 decades. The Vegetation and water bodies also show a sharp decline.
