Landsat TM과 SPOT Panchromatic 인공위성 영상자료를 이용한 토지피복분류 및 분석

Land Cover Classification and Analysis using Remotely Sensed Images Landsat TM with SPOT Panchromatic

The purpose of this study is to obtain land classification map by using remotely sensed data; Landsat TM and SPOT panchromatic, and to compare their results with statistical data and digitized coverage from topographic paper map. The classification was conducted by maximum likelihood method with training sets. The best result was obtained from the Landsat TM merged by SPOT Panchromatic, that is, similar with statistical data. This is caused by setting more precise training sets with the enhanced spatial resolution by using SPOT Panchromatic. The classified map may be useful as a fundamental data to estimate pollutant load in regional scale of agricultural watershed.
