以丽水白云森林公园地形图和二类调查数据为基础数据,借助美国Esri公司开发的ArcGIS9.3地理信息系统构建DEM并进行基于DEM的地形分析。结果表明,该方法可以高效地利用现有的纸质地形图和矢量地形图等生成地势特征图、坡度特征图、坡向特征图,对地形地势进行量化和分析,并为森林公园规划提供数据支撑。该方法不需要投入大量的设备,成本低,速度快,可以为其他森林公园的规划提供一种模式借鉴。
Based on the topographic maps of Lishui Baiyun Forest Park and the survey data of the second type, the DEM was constructed based on ArcGIS 9.3 geographic information system developed by Esri Company in the United States and the topographic analysis based on DEM was conducted. The results show that this method can efficiently generate the topographic maps, the slope characteristics maps and the slope characteristic maps by using the existing paper topographic maps and vector topographic maps to quantify and analyze the topography and provide data for the planning of Forest Parks support. The method does not need to invest a lot of equipment, low cost, fast, and can provide a model for other forest park planning.
