- Changing the Land Surface Temperature and degradation of Ecological Environment: A Case Study in Urban Heat Island areas of Kolkata and Medinipur, India by Using Geospatial Technology
- Aims and Objectives: The present study focuses on determining the relationship of estimated increasing Land Surface Temperature (LST) and urban area’s ecological environment for the city of Kolkata and Medinipur, West Bengal, India. The study seeks to examine that, (a) to retrieve LST from Landsat 8 OLI and TIRS data (2015 and 2019) and prepare spatial LST changeability map for both cities; (b) to evaluate the changing trends and relationship of both urban area’s LST and NDVI distribution; (c) Identify the Urban Heat Island (UHI) and Non- Urban Heat Island (Non-UHI) area and Urban Hot Spot (UHS); and (d) finally, to quantify the changing ecological comfort level for both cities.
Methods: LST, NDVI, UHI, Non-UHI and UHS equations, UTFVI and other measurement techniques.
Results: LST has increased from time to time. The distribution of the relationship between LST and NDVI is inverse. UHI are has been increased and the Non-UHI area is gradually decreased. And decreased the urban ecological comfortably of both cities, but the city of Medinipur has played the role of urban greenness in the present time. So, we need to ‘green city planning’ for every Indian city.
