摘要 造成遥感问题复杂化的重要原因之一就是不同遥感测量方式获取的数据及地面测量数据在尺度上的不一致。在应用不同尺度的遥感数据时 ,尺度转换显得格外重要。该文阐述了遥感尺度转换所解决的问题 ,并针对国内外研究现状 ,分别论述基于像元和基于对象的遥感尺度转换的研究进展 ,对各种尺度转换方法的转换效果进行分析。 One of the important reasons for remote sensing issue complication is that the field measure data or remote sensing data are inconsistent with the applied data on scale.So,scale transformation is very important in application.This paper introduces scale transformation in remote sensing.Aiming at the current researches domestically and abroad,the authors expound the pixel-based and object-based scale transformations in the field of remote sensing respectively,evaluate the transformation results by different means,discuss the trend and prospect.
