摘    要:为了充分考虑到所有影响渠道选线走向的各种因素,笔者主要论述了3S技术在选线中的巨大作用。通过对3S技术的简介,论述了在渠道线路初测和定测中,采用静态GPS定位技术建立控制网、RTK技术测图和放样,方便、快捷地获得高精度的勘测数据;在渠道线路的初次查勘和复勘中,通过对RS图像的复合处理,准确、大量地提取沿线水文地质、地理信息、当地建材和灌区的社会经济状况等情况;在渠道选线中,利用GIS强大的数据综合、地理模拟和空间分析能力对各种信息进行叠加和复合处理,提取各种专题图像,以人机交互的方式,比选出最优线路。最后,根据3S技术的发展趋势,对今后渠道选线的应用进行展望。

关 键 词:全球定位系统  遥感  地理信息系统  渠道选线  应用

Abstract:In order to take into the full consideration all factors affecting ditch line selection, the great effect of 3S technologies on route selection was studied in this paper. By a brief introduction to 3S technology, the author discussed the establishment of control network by static GPS, mapping and locating by RTK, fast and conveniently obtained high-precision surveying data during preliminary survey and location survey of ditch line. Through composite processing of RS images, the author accurately and largely extracted the situations on hydrogeology, geographic information, local building materials and socioeconomic issues of irrigation area etc. along the route in the course of explorations and re-explorations. In the selection of ditch line, using GIS strong ability of data synthesis, geographical simulation and spatial analysis, the author extracted various thematic images via superimposed and composite processing of all kinds of information, got the optimum line by comparison and selection. The prospect on application of ditch line selection in the future is put forward according to development vision of 3S technology.
