Land use and land cover (LULC) is an important component to understand global land status; it shows the present as well as the past status of the earth surface. Land use and land cover are two separate terminologies that are often used interchangeably. This study aims to find out the LULC changes of the Durg block during 11 years in pre‐monsoon (February 2006 to February 2017) and post‐monsoon (October 2005 to October 2016) season. Here, population growth is very high so urbanization and industrialization activity is also high in this block. In the present study, multi‐temporal Landsat satellite imageries are downloaded and image processing has been done with the help of on‐screen visual interpretation techniques on GIS platform. Thematic layers and maps for the year October 2005 and October 2016 (post‐monsoon) and February 2006 and February 2017 (pre‐monsoon) are prepared. With the help of the intersection tool, change map with a change database is generated for LULC change analysis. Lots of LULC changes have been observed between both pre‐monsoon (February 2006 to February 2017) and post‐monsoon (October 2005 to October 2016) maps; it is observed that in pre‐monsoon (February 2006 to February 2017), 0.000153 km 2 agriculture land converted into built‐up land, 85.43 km 2 agricultural land converted into the wasteland, while 10.46 km 2 wasteland is converted into built‐up, where 0.32 km 2 area of water bodies converted into wastelands. In post‐monsoon (October 2005 to October 2016), the area of agricultural land which is converted into built‐up land is 4.86 km 2 , 21.21 km 2 agriculture land converted into a wasteland, 6.47 km 2 wasteland converted into built‐ups, whereas 0.45 km 2 water bodies are converted into a wasteland analysis reveals lots of information about the area, for instance, during post‐monsoon season, agricultural land has shown a decreasing trend by 05.95 km 2 , while built‐up land increased by 11.11 km 2 , due to an increase in population growth. During 11 years, areas covered by water bodies are increased but it doesn't match with the population growth. Land use planners require up‐to‐date and spatially accurate time series land resources information and changing patterns for future management.
