摘　　要：针对海量遥感影像数据批量镶嵌存在操作步骤繁琐、不易修改等问题,提出了一种基于Python语言和FME API的批量栅格数据一键式镶嵌方法,并基于某市的未重叠和重叠栅格数据进行仿真实验,从镶嵌效果图、灰度曲线、信息熵等方面验证了本方法的有效性。Since the problems of cumbersome operation steps and modified difficulty in batch mosaicing of massive remote sensing image data,which reduce productivity severely,a one-click batch mosaicing method for raster data based on Python language and FME API was proposed.Experiments has been carried out based on the non-overlapping and overlapping raster data of a certain city,demonstrating the effectiveness of the proposed method through 3 indicators,including the mosaic map,grey curve,and entropy.
