This paper utilizes the Normalized Difference Built-Up Index (NDBI) method for built-up city in Surabaya, Indonesia as a case study. Analyzing NDBI parameters from Landsat optical data reveals that Surabaya City saw a 21% increase in built-up land from 2002 to 2022. These findings highlight significant urban development in the city during this period and offer valuable insights for future spatial planning and land use policy formulation.
