Top 3 New Features of the Global Mapper Lidar Module v22.1

Written by: Haley Brown, Technical Content Writer

 

The Global Mapper Lidar Module v22.1 is here! Along with the recent release of Global Mapper, the accompanying Lidar Module offers numerous new and updated tools to improve the software’s point cloud processing functionality. This blog highlights the top three new features of this release: 

1. A New Tool to Regularize Extracted Buildings

A significant improvement has been made to the Lidar Feature Extraction tool, specifically when extracting buildings as 3D vector polygons. Version 22.1 introduces a new option to create more realistic building footprints, walls, and planes with the Regularize option. This setting improves the building’s structure by applying 90-degree angles to the corners and parallel walls to opposite sides. Similar to the Simplify operation, which removes vertices that fall outside a defined boundary, the Regularize option is based on a specified horizontal distance threshold.

2. Expanded Tools for Terrain Painting

Version 22.1 of the Lidar Module offers several new Terrain Painting tools, including new brush options and the ability to paint a slope at a defined angle along or across a line. These advanced slope terrain tools are ideally suited for early-stage planning of earthworks projects such as ramps, ditches, and ramparts.

The latest release of the Lidar Module also introduces new trace mode terrain painting brushes when creating lines and areas, which allow the terrain painting tool to act more like a paintbrush. The Line (trace mode) works like a freehand brush applying the selected operation as the cursor moves. The Area (trace mode) provides a convenient way to edit an area without having to create multiple vertices.

3. Updates to the Pixels to Points Tool 

The Lidar Module’s Pixels to Points tool for creating a photogrammetric point cloud from overlapping images now features the ability to cancel, restart, and re-run already calculated data. Checking the Save Work Files to Allow Resuming Cancelled Operations checkbox saves temporary files during the calculation process so the operations can be conveniently stopped and restarted from where they left off. 

The new Enable Clustering option provides a way to process large datasets at the highest quality level on any computer. Rather than process one large collection of images at one time, this option divides them into smaller groups to perform the high-resolution reconstruction. Clustering eliminates the need to reduce the resolution of the images when working with large datasets on a computer that doesn’t have sufficient memory.
