Modified Built - up Index, built - up area, Landsat 8, Sentinel - 2A


Background and Objectives : The Modified Built-up Index (MBUI) has been developed only for land use classification from Landsat 8 satellite imagery, but it has not been applied to data with higher spatial resolution. Therefore, this research aims to apply MBUI with Landsat 8 and Sentinel - 2A satellite images in the Bangkok Metropolitan Region to assess and verify the accuracy of built-up areas obtained from data with spatial resolution. They are different for use as guidelines in selecting satellite image data to determine built-up areas.

Methodology : The NDVI, NDBI, and MNDWI values were converted to integer values (0 and 254) using the same threshold condition for every image. A random sampling method was used to determine the sample point locations, and the accuracy was assessed using simple and multivariate analytical statistics.

Main Results : The results found that the Landsat 8 and Sentinel - 2A satellite images had built-up areas of 2,956.79 and 2,906.61 km2, respectively, and had KHAT values of 75.36% and 79.71%, respectively.

Conclusions : The NDVI, NDBI, and MNDWI transformation conditions developed for Landsat 8 satellite images can be applied to Sentinel - 2A data for higher spatial resolution and accuracy.
