Incorporation of seasonal land cover to develop seasonally integrated land cover map for change detection in Dhaka mega City.

ABSTRACT: The seasonal cycle significantly alters the spatial extent of land cover (LC); and restricts capturing LC dynamics using a single-date satellite image. This study proposes a new method for producing a Seasonally Integrated Land Cover (SILC) by combining seasonal LCs to capture these rotational land covers. Additionally, SILC has been used to detect land cover changes in Dhaka City between 2000 and 2022. Results showed that SILC exchange occurred among every SILC over the study period, though some were negligible. The major drivers of SILC change in Dhaka City (2000-2022) were the significant expansion of built-up areas (77.80 to 143.75 sq km) and the significant reduction of seasonal wetland vegetation (91.12 to 6.62 sq km). Unplanned urban expansion in and around the city center increased
