摘要
分析基于GIS的重大公路设施安全管理系统,针对系统的特性,提出了系统对空间数据库的要求,完成了空间数据库的结构设计、数据模型设计及空间信息的编码设计,采用ESRI的Geodata-base技术创建了空间数据库,从而提高了管理系统对数据的搜索速度和计算精度及相同数据库之间的兼容性。
The GIS-based major road infrastructure safety management system was analyzed.The requirements of the system for the spatial information database were proposed.The structure and data model of the spatial information database were designed,and the information of spatial features was coded.The spatial information database was created with ESRI Geodatabase.As a result,the search speed and calculation accuracy of the system as well as the compatibility between the similar databases were improved.
