Streamlining Releases with Maintenance and Support

We strive to make the Global Mapper release process as easy as possible.  Our goal is to ensure everyone who wants access to the latest Global Mapper release, has access through our Maintenance and Support program. 

Active participants of M&S are eligible to receive every new version of the software and have full access to Blue Marble’s technical support service free of charge. 

As a consequence of this Global Mapper M&S service, all releases of Global Mapper and the LiDAR Module, including minor releases (20.1, 21.1, etc.) will require a new license.
