erosional pattern

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。
