Blue Marble Geographics offers several training options to help users get the most out of their all-in-one GIS software, Global Mapper: Customized Trainingfor companies or organizations needing tailored instruction based on specific workflow needs; Self-Training, comprised of a series of lessons that users can tackle at home at their own pace; and Public Training courses that cover the extensive functionality of Global Mapper and the LiDAR Module.
While all three options have their benefits, the public training courses, which take place at a variety of locations around the world, come with a handful of perks on top of being great opportunities for users to increase the return on their Global Mapper investment.
In this blog entry, I will list the top five reasons why you should sign up for a public training class, and outline what this training journey looks like.
1. GIS training for both beginners and professionals
Public training molds to the GIS –skill levels and knowledge of the attendees.
A couple of weeks before the class, attendees receive a Getting Started package, which includes the following resources:
A PDF of the training manual
The data files that will be used in the course
Links to the Getting Started Guide and video
The Self-Training materials
While it’s not required for attendees to look at these resources, the package gives them the opportunity to see the topics covered in the courses. It also gives attendees time to reach out to Blue Marble’s training team with any specific questions or concerns they may have about the material.
This pre-course communication helps trainers understand attendees’ skills in GIS, ensuring that all attendees get the most out of their individual training experience.
2. Hands-on instruction from GIS experts
In a public training class, Blue Marble’s applications specialists walk through workflows that attendees follow, and provide plenty of opportunities for attendees to ask questions.
Introducing functionality that attendees may not have previously known, this hands-on experience allows trainees to apply new knowledge with real data and in meaningful ways. Their earned skills – ranging from basic Digitizer usage, to more advanced functions such as a variety of terrain analysis functions– can later be remembered and practiced at home with the training manual and data files trainees will take with them.
3. A resume builder with an official certification
The complete Global Mapper training course is a three-day program incorporating two separate courses that attendees can sign up for individually or as one continuous program. The first two days are dedicated to the core functionality of Global Mapper, and the third day focuses on the LiDAR Module and point cloud processing.
Individually, the courses are great resume builders, however when, taken together, they earn attendees an official Global Mapper User certification. If an attendee is just starting their GIS-related career, a certificate can be a valuable credential proving their broad range of terrain analysis, 3D data editing, LiDAR processing skills, and more.
4. An introduction to LiDAR and point cloud processing
With increased access to affordable ways of collecting LiDAR and point cloud data, it’s become more important for GIS professionals to understand what to do with this data and to have access to tools that can efficiently process it.
The third day of training focuses on point cloud processing, covering a range of topics, including: LiDAR filtering and editing techniques, photogrammetric point cloud creation, feature extraction, and more. Whether trainees are just starting to use point cloud data, or if they are experienced, this one-day intensive class will cover everything they need to know about Global Mapper and the LiDAR Module’s capabilities.
5. A networking opportunity – connecting with GM users
Supplementing the learning experience, the public training courses also offer the opportunity for trainees to meet other members of the Global Mapper user community and to network within the industry. A broad range of professionals – from government workers to UAV pilots– attend and benefit from Blue Marble’s training courses, which makes these courses rich in a different way every time.
Public Training – A valuable GIS experience
Whether it’s to boost a burgeoning GIS career or to re-energize and enrich a mature one, Blue Marble’s public training is a valuable experience that provides insight into the basics of Global Mapper, lesser known software features, certification, and networking opportunities.

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.
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.
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.
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.
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.
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?”

Billy Noble, Applications Specialist at Blue Marble Geographics, answers questions that come into the technical support inbox. In this video, Billy demonstrates how to maintain the colors of a point cloud when converting it from a LAS format to a GeoTIFF in Global Mapper.
One of the highlights of the version 20 release of Global Mapper is a new tool for generating a 3D mesh or model from a selected LiDAR or other point cloud points. The resulting layer contains a complex vector feature comprised of an array of abutting triangles that, when displayed in Global Mapper’s 3D Viewer, take the form of a realistic three-dimensional representation of the object. As is typical with Global Mapper, the process of creating a 3D mesh is remarkably straightforward.
