Population growth increases the need for shelter which has an impact on various changes causing the need for space to increase. This need will cause the replacement of forests, gardens or city parks into buildings, housing, highways and others. This study aims to determine changes in the total area of building density in Payakumbuh City from 2001 to 2021. The research method used is the spatial analysis method, namely using NDBI analysis.
