Abstract:	本研究之目的在於利用尺度轉換方法，將高解析度衛星影像以雙線性內插及立方褶積取樣法將尺度轉換為1 m, 2m, 4m, 10m, 20m, 30m, 100m, 250m等8 組共16 幅不同尺度之影像，並依此多重尺度影像進行土地利用分類，比較分類結果之正確性，以尋求一最適合於台灣農業型態之影像尺度。結果顯示衛星解析度並非愈高愈好，而是應該配合地面特性而選擇合適之衛星尺度。高解析度之衛星影像通常取得之成本較高，影像涵蓋範圍較小，影像處理所需電腦時間長。 The purpose of the study was to use the bilinear interpolation and the cubic convolution scale transferring techniques, converting high resolution Quick Bird image to 1, 2, 4, 10, 30, 100, and 250 m resolutions, respectively, and to examine the accuracy o
