As an example of map repackage, in this paper, three digital maps including land use map, soil erosion map and physiognomy map were repackaged by use of overlay to produce a new map of soil eros.
对土地利用图进行信息的挖掘,结合岛状地的界定,提取了其中的岛状地信息;与天然性程度的信息源进行融合,得到了天然岛状地信息;再与土壤侵蚀图、地貌图信息重组,最终得到了土壤侵蚀背景值信息,生成土壤侵蚀背景值图。
