| Abstract: | This paper present a change detection analysis of land use/cover in
Pulau Indah, Selangor Malaysia using a time series of Landsat Thematic Mapper (TM) imagery for the years of 1995, 1999 and 2005. The work aims at mapping the extent of mangrove resources, to detect the changes of mangrove area and to study the driving forces that have led to the changes of mangroves in Pulau 1ndah. Using Maximum Likelihood algorithm, the supervised classification procedure ·was used to classify the images which produced seven land/use classes viz water urban, grasslands, oil palm,mixed crops, mangroves and cleared area. The area of mangroves jar the years 1995,1999 and 2005 were estimated to be 7,738.4 ha, 6,648.1 ha and 6,524.1 ha, respective!.)!. The decreased in mangrove areas for the first and second intervals were at the rate oj'2. 73% and 0.24% per annum, respectively. The accuracy of classified maps was evaluated using
classification error matrices. From an individual classification, the overall ac accuracies of the 1995,1999 and 2005 thematic maps were 98.0%, 97.1% and95.8%, respective~)I, The decrease in mangroves in Pulau 111dahfor both intervals was mostly attributed to their conversion to urban areas driven by the government policies to transform part of the island into industrial park.
