On September 21, one of the most prestigious geospatial events took place!
You guessed it! It was the 25th Anniversary Blue Marble User Conference.
So, there might be a chance that you haven’t actually heard of this event. That’s ok! I’m writing this to convince you that, whether you are a Blue Marble software user or not, you should know about this conference.
Here are the five reasons why you should join us at the Blue Marble User Conference next year:
1. I’m there! … and Global Mapper architects, developers, and experts are too
Yes, I’m there running around taking pictures and recording video (and eating the food), but what’s more valuable to you are the software developers and resellers who are there to hear your questions and requests.
This particular Blue Marble User Conference was especially valuable because the Global Mapper guru Mike Childs and our international resellers were there. After the day’s presentations and software demonstrations were over, Mike answered questions and heard software suggestions from attendees while our product manager jotted down the ideas.
It’s a part of Blue Marble’s core values to welcome and encourage users to be part of the development process. That user-to-developer communication is usually in the form of emails, but at a Blue Marble conference, users can communicate directly with the experts and know their ideas will make it to a discussion in our development meetings.
2. You will be inspired by presentations from distinguished GIS professionals
Did you know that scientists know more about the surfaces of Mars and the moon than they do of the Earth’s ocean floor – aka 75% of the world’s surface? I didn’t.
At this Blue Marble User Conference, Larry Mayer, Director of the School of Marine Science and Ocean Engineering and Director of the Center for Coastal and Ocean Mapping at the University of New Hampshire (phew! Long title!), delivered a presentation on the advancements in sonar and visualization technology for exploring the sea floor. He explained how the technology has helped in the discovery of 3,000-meter high mountains in the Arctic, D-day wrecks, the behavior of whales, and the history of climate through the impact of ice on the sea floor. He touted that investing in more ocean research would help us, people of the world, gain a better understanding of our planet.
Our second keynote speaker and CEO of Aerial Filmworks, Ron Chapple took attendees from exploring the deep with Larry to examining the Earth from above. Ron talked about the challenges that came with producing the Pulitzer Prize-winning documentary “The Wall”, which analyzes the impact of the proposed wall along the border between the U.S. and Mexico. His role in the project was to shoot aerial footage, over which he highlighted the location of the 2,000-mile long border using Global Mapper.
I was surprised to learn how difficult it was for the team of “The Wall” to accurately represent the curvy U.S.-Mexico border in the video.
My point is that BMUC includes amazing presentations by distinguished GIS professionals that give insight into projects that are relevant to the industry today.
3. You will leave smarter and gain Global Mapper “Tips and Tricks”
In between presentations at this year’s BMUC, Senior Applications Specialist David McKittrick took a few minutes to share some “tips and tricks” on how to use Global Mapper. The tips ranged from how to use the multiview display, smooth contours, view data in Google Earth, and create a terrain cutaway.
David also presented on the recent release of Global Mapper 20 and the LiDAR Module, which offers streamlined map layout tools, the ability to create a point cloud from a 3D mesh, a new eyedropper tool for selecting features, dramatically faster loading speeds for working with vector files, and a lot more.
All of these demonstrations were followed by an opportunity for attendees to ask questions that would help them apply these techniques to their own projects.
4. You will eat with other GIS professionals and have a chance to win a prize
Throughout the day, drinks and snacks were available, and at noon we provided lunch. During lunch, we challenged our attendees to participate in a Where in the World Geo-Challenge, in which they were asked to guess the names of geographic features in a slideshow.
At this year’s BMUC, we came prepared with a tiebreaker question, since we expected that a room full of GIS professionals would easily be able to guess all of the features correctly. The winner of the challenge went home with a gift card to the Blue Marble Emporium.
5. You will spend only $25 to attend
So why wouldn’t you attend BMUC if it’s only $25 for a day full of GIS presentations, networking, and lunch?!
They had me at “lunch”, so … I’m not sure why you wouldn’t register.
Stay tuned for future Blue Marble User Conferences
All jokes aside, BMUC truly has a lot to offer GIS professionals, even if you aren’t a user of Blue Marble software. From the insights of our keynote speakers, to the latest software developments and one-on-one interactions with our experts, BMUC is a great opportunity to connect with Blue Marble staff, have a direct impact on the software you use, and to network with members of the GIS community.

Did you catch Global Mapper on television over the summer? In an episode of the Travel Channel show, “Expedition Unknown,” the production crew visited Guatemala in search of Mayan Ruins. A team from LiDARUSA, longtime Global Mapper users, were also involved in the project, collecting LiDAR data for the Mirador Basin Project. Using a combination of drones and helicopters, the data was collected and processed, revealing an uncharted Mayan causeway. As you will see in the footage below, Global Mapper was used to classify bare earth and to view the model that was generated.
No need to worry about this brief cameo going to our heads, the “As Seen On TV” people won’t let us use their logo.
What’s New in Global Mapper version 20?
If you are like most people, it’s unlikely that you take the time to read the plethora of dialog boxes that appear when installing software but if you did, you might actually learn some interesting details about the application. In the case of Global Mapper, one of the windows that beckons for your attention is the “What’s New…” list. While we understand the eagerness of most users to repeatedly click the Next button and finish the installation process so they can “play” with their new toy, it might be worth pausing on this one for just a moment.
Blue Marble’s development process requires each new tool, functional upgrade, bug fix, and performance improvement to be meticulously documented and archived. What you are presented within the “What’s New …” list is an abbreviated version of this archive. In a sense, the list offers a summary report of what the development staff has been working on over the preceding weeks and months. It can make for some interesting reading.
For the soon-to-be-released Global Mapper version 20, there are more than 200 individual changes that have been noted. Given the dynamic nature of the development process, this number will likely increase by the actual date of release.
For those of you who do not have the time or the wherewithal to peruse the entire list, what follows, in no particular order, is a summary of five of the most significant new features that you will find in Global Mapper 20.
1) Improvements to the Map Layout function
One of the surprising findings from last year’s Global Mapper user survey was the importance of map printing. For years, the prevailing opinion has been that printed maps would eventually bite the proverbial dust, but this has not been the case. Global Mapper’s Map Layout functionality was completely redesigned a couple of years ago and it has been undergoing continual improvements ever since. For this release we have introduced a new tool for creating a map book or atlas from selected features; a new option to filter the legend by layer; and a custom macro function that allows you to create title blocks with name, company, etc. Suffice to say, if your workflow requires the printing of maps, Global Mapper 20 has all the tools you need.
2) Support for Windows Tablets with improved touchscreen functionality
While Global Mapper has always been supported on Windows-based touchscreen devices, certain actions and UI procedures have been difficult. In version 20, there have been significant improvements that allow a wider range of actions to be controlled with your fingers. Pinching to zoom the map is now supported as well as swiping with two fingers to pan the map in both the 2D and 3D views. Previous enhancements to support touchscreen interaction include, touching the screen to activate contextual menus and tapping on the screen with any of the digitizing tools enabled to place points or vertices.
3) Ability to create a point cloud or flattened orthoimage from a 3D mesh or model
Creating a point cloud, similar in structure to LiDAR data, from an existing 3D model or mesh may seem like an inverted procedure. It is the reverse of what would be considered a normal workflow. It does, however, open up a number of interesting 3D analysis workflows, in which the source data is an existing 3D mesh. For instance, the point cloud created from the model can be readily classified, edited, and filtered using Global Mapper’s LiDAR processing tools, and points representing ground can be used to create a DTM. Version 20 of Global Mapper not only offers this new point cloud creation tool but it also offers the option to create a flattened orthoimage derived from the colors in the mesh.
4) Speed improvements when loading large vector files
Citing any type of performance improvement as a new version highlight is often perceived as subjective and difficult to quantify or validate. In the case of Global Mapper 20, the improved speed when working with larger vector files is tangible. During our internal testing, the load time for a specific large shapefile was measured at just over four minutes in version 19 of Global Mapper. In version 20, on the same multi-core machine, the load time was shaved to 2.5 seconds. That’s almost 100 times faster. Improvements have also been made to the rendering of large vector files in the 3D View.
5) Eyedropper tool for accurate color selection
Perhaps not a major functional upgrade, however, when considered in the context of one of the author’s favorite Global Mapper tools, it is a godsend. The tool in question is a feature informally referred to as “Raster Vectorization” or, to give its proper name, “Create Area Features from Equal Values”. The premise is simple: By identifying a specific color in an image, you can create polygons that enclose the extent of the pixels of that color or you can expand the tolerance to accommodate similar colors. Previously, fine-tuning the color selection involved manually entering the required RGB values. In version 20, there now is a color picker option, with which you simply click the section of the raster image that you want to extract. This color picker is also available when choosing a transparent color for a raster layer.
And a couple of bonus highlights for LiDAR Module users:
Tool for creating a 3D model or mesh from selected LiDAR points
The underlying technology that enables the creation of an orthoimage was incorporated into Global Mapper within the Pixels-to-Points tool, introduced in the LiDAR Module in version 19. As a byproduct of the photogrammetric 3D point cloud generation process, there is also an option to generate a flattened raster representation of the area in question. Previously, the only way to create either of these data outputs was from drone images. With version 20 of the LiDAR Module, there is now an option to create a mesh or orthoimage from selected points in an existing LiDAR file or point cloud.
Option to spatially thin a point cloud
The LiDAR Module offers an extensive array of point cloud filtering and editing tools. Among the options are: deleting selected points, geographically cropping a point cloud, removal of noise points, manual or automatic reclassification of points, and horizontal or vertical shifting of the point cloud layer. Added to this list in version 20 is a new function to spatially thin a LiDAR layer. This tool allows the user to specify a target resolution for the point cloud which eliminates redundancy, reduces file size, and improves performance.
Version 20 Coming in Mid September
Global Mapper 20 is scheduled for release in the second half of September 2018. Check your inbox or visit bluemarblegeo.com to find out when it is available for download. As always, you can activate a free two-week trial and if you have time, check out the full What’s New list to see what improvements have been made to your favorite Global Mapper tools.
Monitoring a Coastal Dune Ecosystem
Cultivating a sense of moral responsibility for the environment involves more than public service announcements — it’s based on scientific knowledge.
The U.S. Fish and Wildlife Service works to conserve and protect natural resources, such as species on the federal endangered list, through observing changes in the environment and what those changes impact. As one of the bureaus of the Department of Interior, the agency chooses Global Mapper to assist in this environmental research.
The bureau’s Spatial Ecologist Paul A. Lang specifically monitors the habitat of three subspecies of beach mice:
- St. Andrew beach mouse (Peromyscus polionotus peninsularis)
- Choctawhatchee beach mouse (Peromyscus polionotus allophyrs)
- Perdido Key beach mouse (Peromyscus polionotus trissyllepsis)
The mice inhabit the coastal dune ecosystem along the northern Gulf Coast of Mexico in the panhandle of Florida – an area vulnerable to impacts due to tropical storm events and sea level rise. Lang is interested in gaining a greater understanding of the habitat for the long-term conservation of the beach mice. Lang uses Digital Terrain Models (DTMs) for 2015 in order to investigate sea level changes.
A Lack of High Resoultion DTMs
The most important consideration when embarking
on any GIS project is ensuring access to appropriate and clean data.
One of the challenges that Lang has faced in his work is the lack of a high resolution DTMs of the area in which the mice live for certain years. As a solution, Lang accessed publicly available Topobathy LiDAR data from the U.S. Army Corp of Engineers (USACE). This high density point cloud data was collected aerially and was obtained directly from the USACE and from the National Oceanic and Atmospheric Administration’s (NOAA) data clearinghouse.
In order to integrate this data into his research, Lang needed software that had the tools for generating accurate DTMs from the LiDAR data without a steep learning curve.
Generating DTMs in Global Mapper
Lang chose to use Global Mapper and the accompanying LiDAR Module for his habitat mapping.
With a few simple steps, he generated the high resolution DTMs he needed for his research. First, he imported the .las files into Global Mapper and cropped them down to the area of focus. After visualizing and examining the characteristics and metadata of the point clouds in the software, Lang determined that further classification and clean-up was unnecessary. Second, he examined the inherent statistics of the data to get a better sense of the resolution he could create in the resulting DTMs. Third, he used the Create Elevation Grid tool to generate several DTMs that tested different values of No Data distance in order to fill gaps in the point clouds. After these tests, Lang arrived at high resolution DTMs based on the LiDAR data he obtained from the USACE.
From there, Lang was able to use the Simulate Water Level Rise functionality in Global Mapper to visualize potential water inundation on the mice habitat.
The Benefits of Global Mapper
According to Lang, he chose Global Mapper for his analysis because he didn’t find other software as “straight-forward” for processing LiDAR data. Global Mapper’s easy-to-use platform allowed Lang to quickly and accurately generate the high resolution DTM he needed without taking time away from his research.
Global Mapper allows for easy visualization, editing, and filtering of LiDAR and other point cloud datasets. The addition of the LiDAR Module, expands this functionality with auto-classification tools, automatic and custom feature extraction, point filtering options, and numerous other point cloud editing capabilities.

For many, summer is a time for relaxing, for taking your foot off the gas, for being lazy. Not at Blue Marble. We are busy preparing for the next major release of Global Mapper in just over a month, planning our hectic autumn travel schedule, and making the final preparations for our 25th anniversary user conference here in Maine. In this edition of Blue Marble Monthly we formally invite you to join us at BMUC. We also hear from Sam Knight about becoming a licensed drone pilot; we discuss the differences between LiDAR and PhoDAR; and we challenge your geographic prowess in the Where in the World Geo-Challenge.
We hereby cordially invite you to Blue Marble’s home state for our User Conference (BMUC), as we continue to celebrate our 25th birthday. Not only will you have a chance to meet other users and learn about the latest software developments, but you’ll also hear from some interesting presenters including Ron Chapple who will be speaking about his work in the Pulitzer Prize-winning project, “The Wall”.
Ready for the kids to go back to school? Sorry, we can’t help you with that, but we recently sent our own Sam Knight back to school to learn what it takes to become a licensed drone operator. As we continue to develop tools for the UAV industry, it is essential that we have the first-hand knowledge of what is required. For Sam, this was a journey into unknown territory.
Blue Marble’s development process has always relied on direct input from users and now you have a chance to be part of that process. Sign up as a beta tester today and we’ll let you know when a beta version of either Global Mapper or Geographic Calculator is available for you to put through its paces.
The Pixels-to-Points tool has caused quite a stir in the UAV industry. Creating a high-density 3D point cloud from a drone would have been unheard of just a few years ago. While the data may look and feel like traditional LiDAR, there are significant differences between the two formats. In a recent blog post, we outlined some pros and cons of each.
In the latest Global Mapper case study, we hear from Michael Frings, General Manager of MFBI Technologies about how the LiDAR Module’s point cloud processing tools played a critical role in planning autobahn truck stops in Germany.
“The fact that the LiDAR Module is so powerful, giving us the ability to handle large point clouds, was the killer argument for us to go with Global Mapper.” – Michael Frings
Simply stated, Global Mapper gives you more functionality for less money. Need proof? Take a look at this short video highlighting some of the terrain processing tools that are available out of the box in Global Mapper. No extensions required.

As with any significant anniversary, Blue Marble’s 25th birthday, which we celebrate this month, offers an opportunity for us to look back at how far we have come while inspiring us to look forward to the next 25 years and beyond. The early impetus behind Blue Marble’s growth was the development of Geographic Calculator, a geodetic application that, at the time, filled a void in the rapidly expanding field of geospatial technology.
To pay homage to the important role that Geographic Calculator has played and continues to play for the company, in this month’s Blue Marble Monthly, we take a look at how the application has changed over time. We also hear from a couple of Blue Marble’s technical staff members as they help us navigate Geographic Calculator’s expansive Datasource; we introduce Blue Marble’s strategic partners in South Africa; and as always, we challenge your geographic prowess in the monthly Where in the World Geo-Challenge.
ON TURNING 25 | A Letter from Our President
Little would Jeff Cole and his compatriots have anticipated that the startup company they established in 1993 in a small town in central Maine, would grow to the extent that it now boasts hundreds of thousands of customers in virtually every country in the world.
As we pause to reflect on the path that has brought Blue Marble Geographics to this point, it is worth taking a moment to acknowledge two groups of people without whom the journey would not have been possible. First, we must recognize the efforts of the many staff members who have contributed their talents over the years. For those who have moved on to other pursuits, rest assured that although you are no longer with Blue Marble, you have left an indelible mark on the success of the company. Second, it goes without saying that we could not have succeeded without our loyal customers. You invested in us and hopefully we have been able to provide you with a viable return on that investment.
Later this month, Blue Marble will be hosting a 25th birthday party for both current and former staff members as well as some key partners and customers. While we cannot invite everyone we’d like to see to this celebration, we hope you can be there in spirit as we look forward to the next 25 years.
Blue Marble President
Since its founding, Blue Marble Geographics has been synonymous with Geographic Calculator. Indeed, for many years, the application was known simply as the Blue Marble Desktop. This innovative software was introduced at a time when companies and organizations were embracing geospatial technology and were facing the inevitable challenges that managing the resulting datasets incurred. The first versions of the Geographic Calculator were relatively basic although the underlying geodetic processing technology was largely the same as it is in today’s release.
To help shed light on some of the more significant changes that have occurred over its 25-year history, we asked Sam Knight, Director of Product Management, to list the five most important differences between the early and most recent versions.
Application licensing is one of the inevitable tasks faced by virtually all software developers. Ensuring that each user is legitimately authorized to use the software provides the necessary finances for companies such as Blue Marble to continue to innovate and to expand the capability of the software. This is very much a win-win situation. License violation, on the other hand, not only inhibits Blue Marble’s ability to improve the software, it is also, well, stealing.
So while some may regard the licensing process as inconvenient, it is a necessary inconvenience. That said, Blue Marble offers a number of creative solutions for streamlining the licensing process, including offering the option to move a license to a new computer.
Many business strategists have suggested that Sub-Saharan Africa is the world’s new economic frontier and with this in mind, Blue Marble is fortunate to have a well-established strategic partner in the region. South Africa-based SMC Synergy is the latest company to feature in the Reseller Spotlight and recently shared some insight on their business, which is increasingly focused on the growth in use of Global Mapper in the region.
The Datasource has been described as the epicenter of Geographic Calculator. It is fundamentally a database containing the detailed definitions of every conceivable variable that can be used in the geodetic calculation process. In the Datasource, you will find over 5,000 projected coordinate systems; over 1,800 coordinate transformations; over 500 horizontal datums; and much more. To the uninitiated, it can be an intimidating component of the application so in a recent webcast, Blue Marble technical staff members Jeff Hatzel and Scott Webber provided some navigational assistance.
May’s Where in the World Geo-Challenge was, unlike the two preceding editions, controversy-free. Seemingly few were overly challenged as almost all correctly identified all five geographic locations. The first randomly drawn name and winner of a copy of Global Mapper is Marnie Dunbar from OGL Engineering. Check out the answers here to see how well you did.
This month another copy of Global Mapper will be given away so why not try your luck.
