Abstract

The purpose of this study was to examine the land use and land cover changes (LULC) in Gombak, Selangor by using remote sensing approach. Comparison of time series data between years of 1989-1999, 1999-2014 and 1989-2014 have been carried out to identify the changes of LULC. The data used in this study were Landsat satellite imagery (TM and OLI-TIRS) and the Selangor Landuse Map 1990 published by Department of Agriculture. Land uses have been divided into five main categories representing water bodies, forest, rubber, oil palm and built-up areas. An accuracy assessment is calculated for the LULC map derived from image classification techniques and 1990's Landuse Map based on Coefficient Kappa and error matrix techniques and the result showed accuracy of 74.5%. GIS analysis of the post-classification images showed real changes of LULC in Gombak for the comparative year 1989-1999 is 13.69%, which increased to 18.65% for the year 1999-2014 and continued to rise to 24.25% for the comparative year 1989-2014. Changes in rubber were found to be the highest compared to other categories of LULC, accounted for -47.73% for the year 1989/1999, while 1999-2014 showed that the built-up area has the highest changes at +44.53% and for the year 1989-2014 rubber has the highest change value at -34.6%. The decline of rubber in Gombak can be attributed to the increasing of built-up area which has taken over the agricultural area. In general, the pattern of LULC in Gombak is in line with the expansion and implementation of development by the local authorities.
