GPS测绘地理信息系统在智慧城市测绘工程中的应用研究

Research on the application of GPS surveying and mapping geographic information system in smart city surveying and mapping engineering

GPS地理信息系统是通过构建地面基站的方式对卫星数据进行修订,从而应用到智慧城市测绘作业中获得更为精准的城市数据,为后续的建设、管理等应用提供有力保障。文章在探讨构建原理与误差标准基础上,重点对其应用的方式及其误差控制规范进行探讨,并结合具体案例对其应用的精确度与准确度进行评价。研究发现,该系统指标仅低于航拍测绘而优于其他方式,具有较高的应用价值。

GPS geographic information system revises satellite data by constructing ground base stations,and applies it to smart city surveying and mapping operations to obtain more accurate urban data,providing strong support for subsequent construction,management and other applications.On the basis of exploring the construction principle and error standards,the article focuses on exploring its application methods and error control standards,and evaluates its accuracy and precision through specific cases.Research has found that the system’s indicators are only lower than those of aerial surveying and mapping,but better than other methods,and it has high application value.
