基于ArcGIS Engine的河道断面生成与数据获取

河道断面分析是河床演变分析的基础。传统河床演变分析方法中的断面分析主要是针对固定断面来进行,分析过程是根据固定断面的实测地形资料,绘制河道断面图,处理数据的工作量较大,且分析依赖断面实测资料的完整性。基于ArcGIS Engine的河道断面生成与数据获取解决了传统河床演变断面分析必须立足固定断面的局限。以河道地形测量数据为基础,利用GIS空间分析,可根据需求任意布设河道断面,河床演变的断面分析不再受到实测固定断面资料的局限。

River Section Generation and Data Acquisition Based on ArcGIS Engine

River section analysis is the foundation of riverbed evolution analysis.The section analysis in the traditional riverbed evolution analysis methods aimed at the fixed section.According to the measured terrain data of fixed section,the river section map was drawn.The traditional analysis method has to deal with tremendous data and its accuracy depends on the integrality of the measured data.The river section generation and data acquisition based on ArcGIS Engine solved the limit of the traditional river section that must depend on the fixed section.Based on the river terrain measure ment data,the river section can be set freely according to the demands by using GIS spatial analysis.The section analysis of riverbed evolvement was not limited by the measured data of fixed section.
