The release of version 18 of Global Mapper in September of last year introduced a completely redesigned interface with significantly improved layer and workflow management as well as dramatically enhanced 3D display. Building on this foundation, version 18.1 further improves the 3D experience with a new option to freeze the 3D View while working in the adjacent 2D view. This streamlines workflow and significantly improves memory usage by eliminating the need to continually refresh the display.

Users of the optional Global Mapper LiDAR Module, which provides advanced point cloud processing tools, can now perform precise quality control of their data against established ground control points. This allows the elevation values associated with each point to be adjusted to conform to the surveyed elevations at these locations.

When creating a 3D fly-through visualization or recording, the flight parameters now include bank angle to more realistically simulate a pilot’s eye view, and variable velocity allowing the flight speed to be adjusted between segments.

Other enhancements in version 18.1 include a new option to calculate a summary of the color statistics in a raster layer within a defined area; faster loading and display of large vector files such as shapefiles; support for many new formats, including exporting of LandXML and importing of RMaps/MBTiles and BPF LiDAR files; and expanded online data options including the General Bathymetric Chart of the Oceans (GEBCO).

Blue Marble Application Specialists will be conducting a live webinar on Tuesday, March 21 during which they will showcase the highlights of this release. This hour-long presentation is scheduled to begin at 2:00 pm (EDT, UTC-5:00).  and it will provide an opportunity to both see the latest tools and to ask questions about the new functionality. Space is limited and registration is required so be sure to sign up today.
