面向城市实景三维建设的测绘地理信息技术创新研究

Innovative research on surveying and mapping geographic information technology for urban realistic 3D construction

城市实景三维建设是利用测绘地理信息技术以三维形式展现城市地理空间信息的方法。通过获取城市的地理空间数据,利用测绘、遥感、GIS等技术手段,将城市的实景、建筑、地形等元素以三维形式进行模拟和展示,实现对城市的真实、直观、全面的表达。基于此,文章阐述了城市实景三维建设中测绘地理信息技术应用的优势,分析了城市实景三维建设的基本原则,进行了面向城市实景三维建设的测绘地理信息技术的创新性研究。

Urban real-life 3D construction is a method of using surveying and mapping geographic information technology to present urban geographic spatial information in three-dimensional form.By obtaining geospatial data of a city and utilizing techniques such as surveying,remote sensing,and GIS,the elements of the city’s reality,architecture,and terrain are simulated and displayed in three-dimensional form,thereby achieving a true,intuitive,and comprehensive expression of the city.Based on this,this article first elaborates on the advantages of the application of surveying and mapping geographic information technology in urban real-life 3D construction,then analyzes the basic principles of urban real-life 3D construction,and finally conducts research on the innovation of surveying and mapping geographic information technology for urban real-life 3D construction.
