Global Mapper 20 not only offers the ability to create point clouds from 3D meshes, but also offers the option to create a flattened orthoimage derived from the colors in the mesh.

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.


Map Layout tools have been streamlined 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.

Global Mapper 20 now offers a color picker option, with which users can simply click the section of a raster image that they want to extract color from.

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.

Version 20 of the LiDAR Module will come with a new function to spatially thin a LiDAR layer. This tool allows users to specify a target resolution for the point cloud which eliminates redundancy, reduces file size, and improves performance.

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.

What has been your most interesting or challenging sales or support experience?

There was one particularly challenging sale to a leading telecom company in India, which we closed last year. The company had been using MapInfo for several years and we had conducted series of demonstrations of Global Mapper at various levels within the management of the company. After eight months of effort, we finally convinced them to buy Global Mapper. The highlight of this sale was the introduction of the Floating License of Global Mapper. Since this company desperately wanted to be able to quickly move their Global Mapper license from one machine to another, we discussed their issue with members of Blue Marble staff several times, which ultimately resulted in the introduction of a floating license. Interestingly, in past few sales we have noticed that clients have been preferring the floating license option over a standalone license of Global Mapper.

Other than reselling Blue Marble software, what other services do you provide?

Over the last several years, Schnell has been providing GIS services to clients based on Global Mapper. We also resell other geotechnical engineering software products like GEO5. GIS services include digitization of the road networks of various Indian cities as well as digitization of land records for government irrigation departments.

How has your partnership with Blue Marble benefited your business?

In early years of the company, Schnell was carrying out GIS digitization projects mainly for government departments. After we established a partnership with Global Mapper and later Blue Marble, Schnell started offering Global Mapper as commercial off-the-shelf product. With Global Mapper, Schnell was able to expand its client base to educational institutions as well as Indian defense and major private companies. This has given excellent boost to the top-line as well bottom-line of Schnell.

Timely co-operation by the Blue Marble team has always kept us motivated to grow our business every year.
