摘要
在地理空间信息不断完善、发展规划更加科学的大环境下,多运用信息化的手段收集更加精确的工程测量数据能够更好地帮助技术人员掌握基础的地质信息,在城市的规划发展和立体交互式的产品当中都具有较强的应用价值和发展前景。GIS系统中对于地理信息数据的应用显示更为灵活,也是3S技术当中重要的组成之一。本文将系统性地介绍地理信息系统的基本概念与功能,结合其工作流程和运用意义,详细讨论在测绘工程当中的具体应用和发展趋势。
In the environment of geospatial information continuously improving and development planning becoming more and more scientific,more use of informatization means to collect more accurate engineering survey data can better help technician master basic geological information.It has strong application value and development prospects in urban planning and development and three-dimensional interactive products.The application and display of geographic information data in GIS system is more flexible,and it is also one of the important components of 3S technology.This paper will systematically introduce the basic concepts and functions of geographic information system,combined with its workflow and application significance,and discuss in detail its specific application and development trend in surveying and mapping engineering.
