초록

Landsat images were globally used to monitoring the Earth's. But it is not positively applied to a field of environment such as coastal environment, heat island effect and drought condition and so on. Until recently, Information about a ecology natural environment came to do by direct investigation. But Information about a ecology·natural environment of wide area were quickly getting possible with the progress of remote sensing technique. Specially, the up-to-date characteristic information about an ecology·natural environment as the basic intelligence for a country development activity are very important. So, it applies the satellite images that the periodic observation of data is possible. In this study, We planned the function which is possible helping the renewal of an ecology·natural environmental information using Landsat imagery. Also planned the DB suitable for these purpose. For application of thermal infrared band images we developed the function that extracts an isothermal line. It used the thermal infrared band images and it grasped a temperature distribution. The result is useful in analysis of the city heat island effectiveness.
