Global Mapper update improves 3D tools

Blue Marble Geographics is offering a version 18.1 update to Global Mapper that includes numerous functional enhancements and introduces an new tools, upgrades to existing components, performance improvements and support for new formats and online data sources.

The release of version 18 of Global Mapper in September 2016 introduced a redesigned interface with significantly improved layer and workflow management as well as 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, speed improvements when rendering raster or 3D model formats, and improved functionality for creating 3D fly-though visualizations. For lidar module users, a new data quality-control tool is available for adjusting point cloud elevations to match surveyed ground control points.

Blue Marble’s GIS software is used by hundreds of thousands customers throughout the world who need affordable, user-friendly, powerful GIS solutions. Users are in industries including software, oil and gas, mining, civil engineering, surveying and technology companies, as well as government departments and academic institutions.

The release of version 18.1 offers numerous enhancements that are a testament to the ever-increasing importance of 3D data. Global Mapper’s 3D view, which introduced the ability to display an “infinite view” of all loaded 3D data in version 18, now offers the option to pause the 3D rendering when interacting with the 2D map. This streamlines workflow and significantly improves memory usage by eliminating the need to continually refresh the display.

The rendering speed for 3D raster layers as well as 3D models has also been drastically improved. 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).

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.

“With more and more data having a height or elevation component, the importance of Global Mapper’s 3D viewing capability is underlined,” stated Blue Marble President Patrick Cunningham. “For several years, our development priority has been to optimize the user experience when interacting with lidar, DEMs or other 3D layers and with the release of version 18.1 we are seeing some of the results of that effort with more display control, improved 3D interaction, and stunning 3D visualization.”

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 p.m. (U.S. Eastern Time) 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.
