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.

Blue Marble Monthly GIS Newsletter – March 2018

Product News, User Stories, Events, and a Chance to Win a Copy of Global Mapper Every Month

A lot has happened at Blue Marble since our last missive just a month ago. Those of you who keep up with the latest company happenings are probably aware of the latest update to Global Mapper. The availability of version 19.1, which was officially announced shortly after February’s newsletter, includes several significant new and updated features. This month we formally introduce this version by offering you an opportunity to download a free trial, and by inviting you to view a webinar showcasing the capabilities of this release.

Also this month, we announce our plans for our 25th anniversary Blue Marble User Conferences; we chat with our partners at 4DMapper about the innovative work they are doing with the Global Mapper SDK for data processing and management in the cloud. We also discuss the various licensing options that are available for Global Mapper, and we challenge your geographic proficiency in the Where in the World Geo-Challenge.

Global Mapper 19.1 is Now Available

Product News | Global Mapper 19.1 Hits the Virtual Shelves

When version 19 of Global Mapper was introduced in September of last year, the two major functional enhancements were the introduction of the tabular Attribute Editor and the launch of the Pixels-to-Point™ tool for photogrammetric point cloud creation within the LiDAR Module. The recent release of version 19.1 offers an insight into Blue Marble’s unremitting development process, with significant new functionality having been added to these two components. The Attribute Editor now boasts a powerful multivariate querying tool and the Pixels-to-Points tool offers the option to create a 3D Mesh. If you are already using version 19, this upgrade is complimentary. For everyone else, a free evaluation is available.

 

4DMapper Uses the Global Mapper SDK

Partner Spotlight | 4DMapper, a Cloud-Based Geospatial Platform

The Global Mapper Software Development Kit (SDK) provides an opportunity for developers to incorporate much of the data processing functionality of Global Mapper into a third party platform. This establishes the technical foundation for some innovative products and services, exemplified by 4DMapper, an Australian geospatial technology company that provides an enterprise cloud platform for managing, visualizing, and collaborating on geospatial data. Blue Marble recently teamed up with 4DMapper to produce a video illustrating common workflows in Global Mapper and how they can now be performed in the cloud. We also chatted with them about why they chose the Global Mapper SDK.

 

Global Mapper Licenses

Projections | What Global Mapper License is Right for You?

These days, it seems you need a license for everything. Want to own a dog? You need a license. Driving somewhere? You need a license for that as well. Want to buy and sell real estate? Yep, another license. Maybe you should just stay home and watch TV. In many countries, you even need a license for that. In each of these situations, a license provides the means to ensure legitimacy and protection against misuse. The same is true with Global Mapper licenses. The revenue from your license purchase ensures that a small company like Blue Marble can continue to develop the software upon which you depend. Thankfully, there are numerous licensing options available to meet the needs of every individual, company, or organization.

 

3D Path Profile Lines in Global Mapper

Did You Know? | Creating 3D Lines from the Path Profile Tool

Most Global Mapper users are probably familiar with the Path Profile tool and its ability to create a cross-sectional view of the terrain or, if you have the LiDAR Module, of a 3D point cloud. What you might not know, however, is that you can now create series of custom-spaced profile views perpendicular to a defined path and that you can export these profiles as 3D line features. Viewed in the 3D Viewer, these lines offer a unique perspective of the terrain.

Where in the World Geo-Challenge

Where in the World Geo-Challenge

Judging by some of the responses that we received for February’s Geo-Challenge, the five locations were somewhat obscure. Congratulations to those of you who successfully identified all five, especially Galešnjak, sometimes referred to as Lover’s Island, in the Adriatic Sea. This month’s winner is Allan Mathewson. Allan will shortly be receiving a complimentary copy of Global Mapper. Click here to see how well you did.

For March, five slightly less challenging locations await your perusal, with another copy of Global Mapper up for grabs.
