At a fraction of the cost of comparable applications, the Global Mapper LiDAR Module is a must-have for anyone using or managing terrestrial or airborne LiDAR as well as other point cloud datasets.
The Global Mapper LiDAR Module is an optional enhancement to the software that provides numerous advanced LiDAR processing tools, including automatic point cloud classification, automatic extraction of buildings, trees, and powerlines, cross-sectional viewing and point editing, custom digitizing or extraction of 3D line and area features, dramatically faster surface generation, LiDAR QC, and much more.
Additional functionality offered in the LiDAR Module includes:
The LiDAR Module was first released with Global Mapper v15 and a host of new LiDAR tools have since been added. Building on the existing functionality for identifying ground, building, and vegetation points in an unclassified point cloud, version 17 of the module, which was released in September 2015, includes a powerful new tool for detecting and automatically reclassifying above-ground utility lines. After customizing the reclassification parameters, such as minimum height above ground and linear offset threshold, the points representing power lines are automatically attributed with the Wire - Conductor ASPRS LIDAR class. Analysis of linear patterns in these reclassified points can subsequently be used to create 3D vector lines.
Addressing a major concern among LiDAR users, the latest release of the Global Mapper LiDAR Module provides an efficient and effective way to remove noise from point cloud data. This powerful filtering tool can reclassify or automatically delete any points that are beyond a prescribed elevation or height above ground threshold within a local area. Other enhancements to the module include dramatically faster data rendering and processing as well as updated filtering tools for selecting and, if necessary, removing points based on class, return intensity, color range, and many other parameters.
The module also offers a powerful new 3D feature extraction or digitizing tool. Utilizing the new perpendicular profiling function, a series of points can be placed in successive profile views resulting in the creation of 3D areas or line features. This provides a very easy way to digitize highly accurate 3D features from LiDAR or terrain data, such as road edge and curb lines, powerlines, and buildings.
The LiDAR Module offers a tool for verifying the vertical accuracy of a point cloud. Using surveyed ground control points, the elevation values throughout the layer can be checked and adjusted if necessary.
The enhanced LiDAR analysis and editing functionality in the Global Mapper LiDAR module is offered at a significantly lower price than similar applications. The cost of activating this module is on par with the cost of purchasing a copy of Global Mapper with flexible licensing options for available for network, enterprise, and academic use.

The Global Mapper LiDAR Module is embedded in the standard version of the software and is activated using an appropriate license file or order number. As with the full version of Global Mapper, the LiDAR Module can be activated on a trial basis by requesting a temporary license. Click here for instructions on how to activate the module.
