基于MapGIS的城市地质信息系统的构建——以镇江市为例

Construction of Urban Geological Information System Based on GIS——A Case Study from Zhenjiang City

城市地质的信息化主要是从城市地质环境特征出发,选择或改进地质技术,更好地服务于城市地质,是城市建设、城市规划的公益性、基础性工作。城市地质信息化的核心部分是城市地质信息系统。据此,以镇江市为例,以镇江市地质大数据为依托,基于MapGIS技术构建城市地质信息服务平台。镇江市地质信息系统的性能集可靠性、易用性、集成性、可维护性和可扩展性于一体,实现了城市地质环境各类信息的管理、浏览、查询和专业分析等功能以及二维及三维信息的对比显示及空间信息与专业属性信息的联动查询。该研究为'数字城市'、'智慧城市'的建设提供新的研究方法,对城市的规划、发展决策提供依据,同时对国内其他城市地质信息系统建设具有指导意义。

The informatization of urban geology is mainly based on the characteristics of urban geological environment,then selecting and improving geological technology to service urban geology better.It is the public welfare and basic work for urban construction and urban planning.The core part of the informatization of urban geology is the urban geological information system.Taking Zhenjiang City as an example.Relies on the geological data of Zhenjiang City,an urban geological information service platform is build based on GIS technology.The performance of Zhenjiang Geological Information System integrates reliability,ease of use,integration,maintainability and scalability.Realize the functions of management,browsing,query and professional analysis of various types of information in urban geological environment.It provides contrast display of 2D and 3D information,and provides the linkage query with the spatial information and the professional attribute information.It provides new research methods for the construction of'Digital City'and'Smart City',and provides a basis for urban planning and development decision-making.It also has guiding significance for the construction of geological information systems in other cities in China.
