Remote sensing and Geographic Information System (GIS) were used to classify and annotate coastal land use of Ko Lak and Klongwan subdistricts, Prachuap Khiri Khan Province. Satellite images of LANDSAT-5 TM with spatial resolution 30*30 meter of 1987 and 2009 were performed unsupervised classification. Coastal land use area was calculated using pixel based technique, which could be classified into 8 categories namely: 1) agricultural areas 2) upland forest and island vegetation 3) mangrove areas 4) airport 5) urban and buildings areas 6) bare soils 7) seascape 8) aquaculture and water body. The results showed that agricultural areas urban and buildings area were increased 1.84 and 0.58 square km respectively, while aquaculture and water body was decreased 2.95 square km.
