LANDSAT-5의 TM과 MSS 데이타의 比較에 관한 硏究

A Study on the Comparison of LANDSAT-5 TM and MSS Data : laying stress on the landuse mapping of Incheon area

本 硏究에서는 LANDSAT-5號의 TM과 MSS 데이타를 比較分析함으로서 TM 데이타의 活用方案에 대한 檢討를 하고자 하였다. TM과 MSS 데이타의 比較는 仁川地域의 土地利用分類 結果를 中心으로 이루어졌으며, 아울러 画像强調處理의 方法에 따른 正確度의 比較도 행하였다. 硏究結果, 土地利用分類에 있어서 TM 데이타가 MSS보다 약 20%의 正確度 向上을 가져왔으며, TM 画像의 强調處理에서는 平滑化處理가 效果的이었음을 알 수 있었다.

In this study, practical use of TM(Thematic Mapper) data was evaluated by comparison of LANDSAT-5 TM and MSS(Multispectral Scanner) data. The comparison of TM and MSS data was achieved by analyzing the result of landuse mapping of Incheon area, and in addition, the comparison of accuracy according to image enhancement method was made. From the results of this study, we found that TM data was more accurate by about 20% than MSS data in landuse mapping, and that smoothing was effective in image enhancement processing of TM data.
