FEATURE  |  Mapping the Turkana Basin

In a blog entry, archaeologist Antonio Kuilan writes about how he used Global Mapper to create high resolution digital elevation models of the Turkana Basin — an area that has produced “key hominin fossils that shape the understanding of our human origins.”

“It is my opinion that what makes Global Mapper powerful is not only its collaborative design team, but their focus on listening to the real-world GIS experiences and needs of scientists, researchers, and other users.”

Top Five New Features and Functions in Global Mapper Version 20.1

Interim releases of Global Mapper typically offer the Blue Marble development staff an opportunity to fine-tune some of the functionality that was introduced in the most recent major release. While the upcoming version 20.1 release includes its fair share of performance improvements and code tweaks, it also offers a surprising collection of new tools covering everything from the Digitizer to scripting. With the release just a few weeks away and the final edits being applied to the underlying code, we take a sneak peek at some of the more significant additions.


Using the new Zoom tool in the Path Profile View.

Path Profile Zooming

The importance of Global Mapper’s Path Profile tool has grown immensely since the introduction of the LiDAR Module. While it is most commonly used to render a cutaway view of a terrain layer, it also displays a cross-sectional view of points in a point cloud and can used to edit or delete selected points. New in version 20.1 is the option to zoom in the profile view – a function that ensures that even the most densely-spaced points can now be individually identified and selected.

Profile Legend

Continuing the theme of improvements to the Path Profile tool, a new option has been added to more clearly define the individual surfaces when rendering profile lines for multiple layers. A legend, which can be placed anywhere within the Path Profile window, shows each line style along with the corresponding surface layer. This is particularly useful when visualizing and analyzing multiple layers representing change over time.


Selecting a default projection.

Default Projection

Global Mapper’s projection management is universally acknowledged for its simplicity. Load any layer and the inherent projection parameters associated with the layer define the display projection. Each successive layer is then automatically reprojected on the fly to adhere to this system. No questions asked. Change the display projection and each exported layer will ultimately include these new projection parameters. In Global Mapper 20.1, an even simpler approach to projection management can be enabled with the assignment of a universal default projection. With this new configuration setting, a specified projection will be automatically applied when creating or importing any new layer.

Vector Gap Closing

When creating abutting polygons, Global Mapper’s snapping functionality helps ensure that the features’ shared vertices are a perfect match, without overlap or gaps. When importing external files, however, such precise geometric integrity is not always the case. A new Digitizer tool available in version 20.1 can be used to automatically correct these errors. The “Close Gaps Between Adjacent Features …” function allows a maximum distance threshold to be established allowing the boundary lines to be perfectly matched.


The “Select LiDAR by Distance” tool can be used to select a particular point type within a defined distance of a feature

LiDAR Proximity Selection

A common use case in point cloud or LiDAR analysis is the detection of encroachment, and a new point selection option in the LiDAR Module provides this functionality to Global Mapper users. The “Select LiDAR by Distance” tool can be used to specify a particular point type (such as powerline), a distance threshold, and a target point type (such as high vegetation). In this case, running the search will highlight vegetation points that are encroaching within a defined distance of powerlines. This tool can be applied in many other workflows and includes the option to detect points within the proximity of 3D line features instead of points.

What is Maintenance and Support and How Does it Affect Me?

If you have purchased Global Mapper and/or the LiDAR Module in the last two years, you have heard from our sales team regarding Maintenance & Support (M&S). But you may find yourself wondering, “What is Maintenance and Support and how does it affect me?”

The “Maintenance” Part – Keep your version of Global Mapper up-to-date

Longtime users know that, with every purchase or upgrade of Global Mapper includes a year of technical and licensing support. This support, along with our knowledgebase, videos, and self-guided training, allows users to explore and experience all Global Mapper has to offer. With customers in mind, we updated our support model in summer of 2017 with a 12-month M&S plan that begins on the date payment is received for an order. M&S now includes all version releases of the software within that 12-month period, allowing customers to utilize the most current version of Global Mapper.

The “Support” Part – The Blue Marble Tech Team is here for you

In addition to providing users access to the most current version of Global Mapper, M&S also includes the unparalleled technical and licensing support we are known for offering. Our technical team is ready to answer any questions you might have, from format questions, to complex workflow scenarios, in a timely manner. Technical Support is not a substitute for training. We offer many training solutions both in person and virtually. For more information please visit https://www.bluemarblegeo.com/solutions/geodesy-training.php .

Maintenance and Support Renewals and License Structure

This M&S model also provides customers with the option to renew their support every year. Some of you will likely have received emails from us in the past few months letting you know that your support has ended, and explaining how to renew your subscription. Please contact the sales team with questions about the renewal option, coverage period, or how to purchase additional licenses.

I’m sure many of you are thinking that since Global Mapper has a perpetual license structure, “How will Maintenance and Support affect that model?” Rest assured it will not affect your license. However, the level of support that you receive is directly related to the status of your M&S. If your M&S is out of date, Blue Marble’s technical and licensing support teams may be unable to assist you.

Blue Marble strongly encourages you to stay up-to-date with M&S, so that you have access to the best software we have to offer. Staying current guarantees the highest level of software support and service, and that you are receiving the latest software fixes and enhancements.

In the coming weeks Global Mapper 20.1 will be released. Are you eligible to use all the great features and enhancements the new release has to offer? Users with current M&S coverage will need to download and license this version of Global Mapper. If your M&S is out of date or if you have questions about the status of your Global Mapper license, please contact orders@bluemarblegeo.com.
