This is because LST is an important key that influences climate, hydrology, ecology and biochemistry. Remote Sensing technology offers various types of satellites to researchers to study the weather and climate. However, MODIS and Landsat satellites are the second most important satellites in studying soil surface temperatures. The objective of this study was to evaluate the effectiveness of both satellites in measuring surface temperature. To achieve the objectives of this study requires both data through pre-processes such as radiometric, atmospheric and geometric corrections. The next step is to convert the digital value of a number using a formula often used by previous researchers in obtaining temperature values. Temperature data from meteorology from the Malaysian Meteorological Department (MMD) is used in determining the effectiveness of the two data by using the correlation method between the temperature values ​​from MODIS and Landsat satellites with the temperature from MMD. The results suggested that the correlation value between temperatures from the Landsat satellite was higher compared to the MODIS satellite. The results of this study are important as a guide for future researchers, students and stakeholders in making choices in the data for their respective studies.</p> ER -
