基于ArcGIS与层次分析法的长输管道选线模型研究

Research on Long-distance Pipeline Route Selection Model Based on ArcGIS and AHP

为了研究更加方便、实用的长输管道选线技术,结合层次分析法和ArcGIS平台技术,以数字高程模型为基础,以层次分析模型得到的影响因素及其权重作为基本因素图层,对各图层因素进行叠加,建立长输管道选线最优路径模型及最优路径轨迹。利用该模型可完成线路平面、纵断面等平面设计,同时可完成工程量的统计,并以三维方式输出。

To research the more convenient and useful technology for long-distance pipeline route selection,combined with analytic hierarchy process and the ArcGIS platform technology,taking digital elevation model as basis,and influencing factors obtained from AHP model and their weights as the layer of basic factors,through stacking the layer factors,pipeline route selection model and optimal path trajectory were built.This model can be used to complete the plane design of route and longitudinal section,statistic of project quantity,and output in a three dimensional manner.
