| 摘 要： | 针对DEM本身存在的缺少关于平坦地区和洼地以及水库或湖泊水流路径的数据信息的缺陷,以及没有较高精度DEM的地区难以构建准确的数字河网的问题,提出利用遥感影像作为反输入修正数字河网的新思路,并尝试了利用遥感结合DEM提取河网水系的方法.应用分析表明该方法可以生成较符合实际的连续的数字河网,而且适用于没有较高精度的DEM的无资料地区。此方法值得进一步研究.

| Abstract: | The problem of the digital elevation model(DEM),such as the lack to handle the flat areas and pits,unable to differentiate lakes from plain areas,and the problem that it is hard to model exact digital channel network in where has no digital elevation model of high precision,were introduced and discussed.The new idea of correcting of channel network using remote sensing was presented,and the approach was tried to present and apply.It is showed that the new approach can model a continuous channel network better match with the observed,and is adapt to where has no digital elevation model of high precision.So it is valuable for further research. |
