Route Selecting Technology Based On Spatial Analysis Of GIS

Under the sustainable development strategy, route optimization design not only requires route pass time short and cost less but also requires the route harmonize to environment and humanities surrounding and community surrounding. Route layout is problem with various factors, multi-objective spatial decision-making which considering not only the conventional factors such as topography, geology, hydrology, traffic but also the factors along the route such as economic, cultural landscape, the ecological environment. The geography modeling methodology method of route layout is used in this paper. The method in this paper is in order to enhance scientific and normative of route layout and economic social and environmental benefits of route layout, and to reduce the negative effects of subjective judgement limitations of decision-maker. It is very important to use the funds rational, and to improve overall efficiency of the route construction investment.This paper propose the application geography modeling methodology to establish route selection cost model based on summarizing existing route selection method , then layout optimum route. four primary factors such as geology, buildings, elevation, terrain slope was selected in the study. Analytic Hierarchy Process and expert hits the minute method are used to make out there factors weight in the route selection cost model. Re-class the route select factors by the property of them, and give power to them. Through calculate the layer with weight to build route selection model. Route selection model of geographic information system which based on the grid data is used to seek the optimum route. Route economic corridor is created.In this paper, the factors such as geological and topographical which general descript by qualitative are descript by power. The route selection modeling problem which has different factors is solved. New idea was proposed to these problems which has various factors and multi-objective decision-make by spatial analysis function of ArcView GIS, route economic corridor is put out. Sensitivity factor change in route selection was reflect in the route economic corridor which has important practical...
