Abstract

The study was implemented by using Landsat TM. This scene covers the areas of Klang, Selangor. The main objective of this study is to evaluate the use of remote sensed information. Remote sensing is a technology to obtain information about the object or phenomenon without having to be physically connected to the object. Remote sensed information is use to gain land surface temperature (LST) using supervised method of Landsat images. The derivation of LST map using remote sensing technique in this study is useful in providing information for analyzing geophysical information over Selangor area, especially dealing with the urban heat island phenomenon. Supervised image classification was used, in which it requires training sites on the image that represent of each desired land temperature category. The delineation of training areas that represent the land temperature is most effective when an image analyst has knowledge of the geography of a region and experience with the spectral properties of the suitable classes. Envi software is used to identified spectral values or signatures associated with the training sites. After the signatures for each land temperature category have been identified, the software then uses all the signatures to classify the remaining pixels. The methodology consist 4 phases; analysis, design, implementation and testing.
