GeoCalc Mode: Projections and Datums

About GeoCalc Mode

Using GeoCalc Mode provides added geodetic support to the Global Mapper application, with the ability to access the Geographic Calculator's geodetic library in the coordinate transformation libraries in Global Mapper.

Instructions for activating GeoCalc Mode in Global Mapper can be found here. You will need a license for Geographic Calculator in order to enable the GeoCalc Mode tool.

Using the Geographic Calculator GeoCalc library in Global Mapper will provide access to:

Worldwide in-depth coverage of any type of coordinate system or geodetic definition
Vertical datum transformation support for dozens of local geoids, ellipsoids, and local offset models
VDatum support for Tidal vertical references in North America
Custom coordinate system support and easy sharing of custom parameters between multiple users
Administrative control of geodetic parameters so users only see and use what you decide

For more information on specific supported datums and coordinate systems for the Geographic Calculator, it is recommended that you install the application, register for an evaluation or user license, and browse the application's Datasource library.
