摘要:
以长江江阴段丁坝两个不同时期的水下地形1:500测量成果数据,使用ArcGIS软件强大的计算分析功能,建立数字高程模型(DEM),提取水下地形的影响因子包括河沙流失与淤积、坡度、粗糙度等,结合直观的图、表进行统计与分析,得出其中的变化值和变化趋势。
Abstract:
Based on the 1:500 survey data of underwater topography of spur dike in Jiangyin Section of the Yangtze River in two different periods, the powerful calculation and analysis functions of ArcGIS software were used to establish a digital elevation model(DEM). The influence factors of underwater topography were extracted, which including river sand loss and siltation, slope, roughness, etc., and change value and trend were obtained by combining with intuitive charts and tables.
