摘要
针对实地考察获取泥石流数字高程模型(DEM)数据往往费时费力,难以满足对泥石流运动研究对泥石流DEM数据需求的问题,以香港大屿山地形图为例,基于Arc GIS Engine开发组件,提出了一种调用Arc GIS Engine所提供的图形绘制功能,以手动方式绘制泥石流堆积体,并通过插值获取泥石流DEM数据的方法,从而实现了泥石流DEM数据自定义生成,满足了泥石流模型研究对DEM数据的需求,也提高了泥石流运动研究的灵活性。
It always costs a lot to get debris-flow Digital Elevation Model ( DEM) data by field studying. To meet the demands of debris-flow motion studies, with the example of Lantau Island map and based on the ArcGIS Engine development kit, this paper put forwards a method of custom generating DEM data by manually drawing debris-flows and interpolating, thus to meet the data demands and get a better flexibility for debris-flow motion studies as well.
