| 摘 要： | 以GIS为基础平台,数据为主线,研究了公路地理信息系统开发中数据处理与数据的集成方法.采集并组织了矢量数据、属性数据和栅格数据,实现了数据的浏览、检索,解决了数据集成中的2个重要问题:空间对象及其属性信息、图像数据的一体化;矢量数据与栅格数据的无缝集成.系统通过提供乡镇、河流、路网等的分布情况,已建公路及拟建公路沿线的相关信息,为路网规划、管理以及拟建公路的选线提供决策支持.

| Abstract: | Based on GIS platform,data processing and integration during highway GIS development are studied.Vector data,attribute data and raster data are constructed and organized.Data browsing and searching are realized.Two key problems are solved: one is composition of spatial object,attribute information and image data; and the other is seamless integration of vector data and raster data.Related information of the region along highways built and planning to build,and distribution of villages,towns,rivers and road net,can be acquired from the software system.Highway GIS can be used to support decision-making in selection of highway routes,in layout and management of road net. |
