尺度效应是遥感应用分析中的一个重要因素,直接影响遥感分析的效果。遥感尺度选择问题已经引起国际遥感界的高度重视。本文首先明确了遥感尺度选择问题的范畴;然后分析了当前遥感尺度选择的方法,并对已有的方法进行了评价;最后就遥感尺度选择的研究方向给出了一些建议。
Scale is an important factor in the application of remote sensing which directly influences the effect of analysis. The importance of scale has been recognized by the international organization of remote sensing for more than four decades. In this paper, the concept of the choice of scale in remote sensing is given firstly. Then, some methods about the choice of scale are introduced and the evaluation is discussed. At last, some suggestions about the choice of scale in remote sensing are proposed.
