Abstract Information related to Land use and Land Cover (LULC) change is important for conservation of natural resources and sustainable development of an area. Siliguri is one of the populated metropolitan of West Bengal, India that has witnessed rapid urbanization. The major challenge is to identify the reason and pattern of urbanization due to inadequate and insufficient data in small cities like Siliguri. This paper has mainly assessed the LU & LC change of Siliguri municipality for the period of 1991-2001, 2001-2011 and 2011-2021. The main aim of the study is to determine the pattern and direction of future expansion. Satellite images from Landsat 4-5(1991-2011) and Landsat 8(2021) were used to extract LU & LC map of the municipality. Supervised classification using maximum likelihood classification was used to developed LULC maps. The supervised classification produced good results with overall accuracy of more than 80%. The change of the LULC pattern was obtained using change detection method. Four major classes viz. Vegetation, water body, sand and built-up have been identified. The analysis shows that maximum transformation has happened in the buildup environment from other land surface features.
