Blue Marble Geographics Releases Global Mapper Pro v25.1, including new automatic Ground Control Point Identification and Positioning for Drone Data Collection

Hallowell, Maine – February 13th, 2024 – Blue Marble Geographics (bluemarblegeo.com) is pleased to announce the immediate availability of Global Mapper Pro v25.1. This update brings a new ground control point manager, the ability to create point cloud subclassifications, and more.

For nearly three decades, Blue Marble’s affordable, user-friendly GIS software has been meeting the needs of hundreds of thousands of satisfied customers throughout the world. 

Ground control points (GCP) in the Pixels to Points tool are now managed in a separate dialog and have the additional functionality of automatically searching for ground targets in possible overlapping images. Each GCP has an x/y/z location that must be manually associated with an image pixel, an essential process that can be tedious at times. The new GCP Manager can locate and place markers on clearly identifiable targets, making the process of using ground control points much easier. 

Terrain Painting is a popular tool for editing elevation values. It’s often used to model future ground construction, remove imperfections in the data, fill holes, and much more. In v25.1, a new Terrain Painting function has been added to the Path Profile tool. The functionalities are still the same, but the Path Profile tool provides the ability to measure and visualize the terrain changes while working from an additional, perpendicular perspective.

Subclassifications, a new training and custom classification feature in Global Mapper Pro v25.1, can be added to classifications to refine further the type of point feature with which it is being worked. Subclassifications are distinct in color and classification labels without losing the functionality of the parent class.

“Global Mapper Pro v25.1 continues to expand on a variety of pro-level tools, “stated Jeffery Hatzel, Product Manager. “The custom point cloud training and classification in our Automatic Point Cloud Analysis tool now has the ability for subclassification – useful when defining a custom feature in a previous classified class, such as identifying roads from the ground. The exciting new GCP Manager in Pixels to Points allows for the automatic placement of GCPs in imagery, bringing considerable efficiency improvements to the workflow. In addition to a variety of new features and improvements to the Path Profile in Global Mapper Standard, the tool now supports Terrain Painting allowing pro users to live edit terrain from a profile perspective.”

Additional updates include a new function in the Compare Point Clouds tool for measuring differences in elevation between point clouds and gridded terrain layers. Also added to existing tools is the option to save the overlap difference grid as a separate layer during Swath Separation Image processing and the ability to import XMP metadata into Pixels to Points from TIFF files if present, improving location information for drone images.
