Gradient Boosting Tree for Land Use Change Detection Using Landsat 7 and 8 Imageries: A Case Study of Bogor Area as Water Buffer Zone of Jakarta

Abstract

The land use change in Bogor regency need to be studied, since it acts as a water buffer zone for the sorrounding area, which includes the capital city of Jakarta. This study aims to analyze the land use changes in Bogor Regency using the gradient boosting tree model. Landsat 7 and 8 imageries of Bogor area in 2008, 2011, 2014, and 2017 are used as the case study. The images are cropped into sub-district level and classified into four classes, which are green area, partial green area, impervious land, and partial impervious land. By comparing two images of classification result between two different years, the land use changes can be determined. This study shows that most land use changes from 2008 to 2017 occur in Sukamakmur sub-district with a percentage of 69.31% (134.0757 km2). Based on the type of land, most land use changes are from impervious area to green area.
