Attribute Management

Vector Features may contain attributes, and Global Mapper has numerous tools for calculating, managing, and querying those attributes.

Note: In any tier of Global Mapper, attributes may be displaying or modified individually for each vector feature using the Feature Info Tool and Digitizer editing tools including Modify Feature Info.
