Global Mapper - LiDAR Module

Global Mapper

Automatic point-cloud classification and feature extraction

The LiDAR Module is an optional add-on for Global Mapper , an affordable and easy-to-use GIS application that offers access to an unparalleled variety of spatial datasets. The applications key benefits include the ability to quickly view and process LiDAR point clouds with a billion points or more. LiDAR analysis has become a widely used technique for generating high-resolution Digital Elevation Models (DEM), including terrain (DTM) and surface models (DSM). With the LiDAR Module users can post-process LiDAR data using popular techniques such as identifying, reclassifying, filter point clouds by classification and/or return type.

LiDAR module features

  • A convenient LiDAR Toolbar for easy access to key editing and analysis functions
  • Multiple gridding options for faster DSM or DTM generation
  • Access to point cloud files containing a billion points or more
  • Automatic point classification tools that automatically distinguish building, ground, vegetation and power lines and above-ground utility cables in unclassified layers
  • Feature extraction functionality to automatically create 3D building footprints, trees and power lines
  • Cross-sectional rendering using Global Mapper's Path Profile tool for viewing and editing the point cloud in a vertical perspective
  • 3D Digitizing or custom feature extraction using the perpendicular profile function
  • Advanced filtering options to efficiently remove erroneous or unneeded points
  • Customizable detection and reclassification of noise points
  • LiDAR scripting commands for streamlining workflow
  • Point colorization from underlying imagery offering photo-realistic point cloud rendering in Global Mapper's 3D Viewer
  • Support for reporting LiDAR statistics
  • Support for importing and exporting most common LiDAR formats
  • Support for NIR (near-infrared) data
