Application of Basic Geographic Information Data in Map Compilation
The article provides a detailed analysis and discussion on the application of basic geographic information data in map compilation.Firstly,it analyzes the distinction and differences between basic geographic information data and map data,analyzes the main contents and advantages of the two,and from the comparative analysis,the advantages of basic geographic information data can be intuitively observed,which further confirms the need to apply this technology in map compilation.Subsequently,it introduces in detail the technical usage process of basic geographic information data in the mapping process,including how to carry out routine operations and how to carry out map compilation with the help of basic geographic information data.At the same time,it also puts forward several key technologies,including creating a map database,designing a symbol system,following relevant principles in the process of designing a symbol system,creating a vector symbol library,and declassifying data.Ultimately,in the process of map compilation,basic geographic information data plays an important role,providing important data references and accurate data content for maps.
