The remote sensing satellite sensor can not only record the visual appearance of the earth’s surface characteristics but also can capture phenomena that cannot be seen by a human, such as the earth’s surface temperature. Bandung is located at a basin-shaped area and has a variety of land cover, natural and man-made. The diversity of land cover is indicated to have an effect on the characteristics of the land surface temperature recorded by satellite sensing sensor. This assumption then examined by considering the land cover type and the value of land surface temperature as its parameters. This research aims to: 1) Estimating the land surface temperature with digital image processing, 2) Visual interpreting of land cover type based on land surface temperature similarity, and 3) Analyze the level of land surface temperature with a variation of land cover type in the south-western part of Bandung Basin. The visual interpretation method was used to obtain a land cover type with high-resolution image. Whereas the transformation of the Landsat 8 thermal band index is used to acquire the land surface temperature. An analysis was carried out to observe the results of land surface temperature estimation and land cover based on land surface temperature resemblance. Then it is expected to be a consideration in terms of determining policies regarding conversion of land cover from natural to artificial forms indicated as a contributing factor to rising land surface temperatures.
