摘要
随着GIS技术发展,传统二维GIS越来越难以准确直观地展示地上地下空间位置关系及空间分析应用。城市地下管线包含地上地下各类管网,为能更加清晰地表现地下管线与地表地物的位置关系,便于管理维护,本文基于超图软件SuperMap10i平台,以山东省鱼台县为例,利用二三维一体化技术,实现以地表倾斜摄影实景模型数据、城市三维模型数据、城市部件数据、数字正射影像图(DOM)数据、数字高程模型(DEM)数据、地下管网专题数据为主构建地上地下一体化空间三维场景。
With the development of GIS technology, it is increasingly difficult for the traditional two-dimensional GIS to accurately and intuitively display the spatial position relationship between ground and underground as well as spatial analysis and application. Urban underground pipelines include all kinds of above-ground and underground pipe networks, in order to more clearly show the location relationship between underground pipelines and surface objects, and facilitate management and maintenance, in this paper, based on SuperMap10 i software platform, taking Yutai county in Shandong province as an example, the two and three-dimensional integration technology is used to construct an integrated three-dimensional space scene mainly based on the ground oblique photography model data, urban three-dimensional model data, urban parts data, digital orthophoto(DOM) data, digital elevation model(DEM) data, and underground pipe network thematic data.
