Keywords:land use, land cover change, remote sensing, Geography Information System (GIS), Landsat, post-classification
The purpose of this study is to detect changes in land use and land cover in the area of Miri, Sarawak using remote sensing. Comparison land use and land cover from 2001 to 2016 was carried out to detect the changes in land use and land cover of Miri district. The basic data used for this change detection study are satellite images of Landsat (TM and OLI-TIRS). The study area was classified into six categories of land use i.e built up, inland forest, peat forest, cleared land, oil palm and water body. Comparison of the classified Landsat imagery in 2001 (TM) and 2016 (OLI-TIRS) shows that there is a significant increase of built-up areas from 4.4% to 11.5% and oil palm cultivation from 9.8% to 43.6%, especially near to urban areas.
