Global Mapper LiDAR Module: Advanced point cloud processing - Download Now >

LiDAR Module

The Global Mapper LiDAR Module is an optional purchase for those interested in advanced features such as automatic reclassification, Path Profile editing of LiDAR points and dramatically faster gridding. Users will leverage the LiDAR Module through the new LiDAR toolbar.


Manual Reclassification

Quickly reclassify points with seven different classification types.

  • Ground Points
  • High Vegetation Points
  • Medium Vegetation Points
  • Low Vegetation Points
  • Building Points
  • Transmission Tower Points
  • Water Points

Automatic Reclassification

Automatically reclassify buildings, trees, ground points and above-ground utility cables with conveniently located button in the LiDAR tool bar. The Global Mapper LiDAR Module features improved classification to filter out likely buildings, trees and power lines along with additional parameters controls in the Ground Classify dialog. Machines with multiple cores will experience faster automatic classification of ground points. The user can also perform automatic classification on just selected points to speed up processing.

Advanced LiDAR Filtering Options

Access the LiDAR filtering options from the "Options" tab in the "Configuration Window" to allow easily filtering by classification and/or return type. Filter LiDAR points by class, elevation, color, scan-angle, source-ID, intensity, height-above-ground, NDVI and NDWI (when available), and return type when exporting, gridding, and selecting from point clouds.

Automatic Extraction of Buildings, Trees, and Powerlines

Feature extraction allows the user to render buildings, trees and power lines for greater visualization of LiDAR data. This new and powerful feature in Global Mapper is something normally only seen in software that costs thousands of dollars for a single user license. The Global Mapper Lidar module enables users to easily and quickly conduct feature extraction rendering appropriately classified lidar points as 2D and 3D feature objects. This powerful data will assist users that wish to create better and more exact earth models with realistically representative objects.

Custom 3D Digitizing and Feature Extraction

Using the new Perpendicular Path Profile function, a series of custom spaced cross-sectional views are created perpendicular to a defined path through a point cloud. 3D vertices can be quickly and accurately placed at regular intervals within each successive profile view. When the sequence is complete, either a 3D linear or area feature is created using Global Mapper's standard Digitizing tool. This is an ideal tool for delineating curbs, utility cables, pipelines, drainage ditches, or building rooflines from high-resolution point cloud data.

Colorize LiDAR Points

Colorize and view LiDAR points as RGB data by using the LiDAR module toolbar button to colorize LiDAR points from loaded imagery in memory with no export required. Users can also apply color from loaded imagery when batch converting to LiDAR LAS/LAZ files. As well as colorize LiDAR points by the following:

  • Color LiDAR by RGB/Elev
  • Color LiDAR by Elevation
  • Color LiDAR by Intensity
  • Color LiDAR by Classification
  • Color LiDAR by Return Number
  • Color LiDAR by Height Above Ground
  • Color LiDAR by Point Source ID

Dramatically Faster Gridding

With robust gridding techniques for faster, extremely flexible creation of elevation surfaces, including smart decimation through binning, and other techniques.

Path Profile Editing

The module also includes the ability to leverage the LiDAR toolbar directly in the Path Profile viewer for faster management, editing and reclassifying of points. The module includes two selection options for selecting points in the Path Profile viewer, to select by a click and drag method or selection by drawing a custom polygon to select points.
