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