Layer Projection Tab

The Layer Projection tab is used to reinterpret the raw vector data to a new projection. This is useful if the wrong projection was selected for the dataset when it was loaded, or if the data set itself indicated some incorrect data. This option is rarely used. For more information about specifying a projection see Projection

For Global Mapper users with access to the GeoCalc libraries, using GeoCalc Mode the Layer Projection tab will allow users to browse the Geographic Calculator datasource for Projections.

Global Mapper Tip: The Elevation Units can be used to specify what elevation units that values in vector data should use, if the elevation units are not explicitly specified in the data. This is useful with 3D Vector Data, to specify the unit type associated with 3D vector features or with ELEVATION attribute.
