Global Mapper Pro

Global Mapper

Advanced photogrammetric point cloud and lidar processing

The Global Mapper Pro 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 Global Mapper Pro users can post-process LiDAR data using popular techniques such as identifying, reclassifying, filter point clouds by classification and/or return type.

Pixels-to-Points™ in the Global Mapper Pro

The release of version 24.0 of the Global Mapper Pro saw the introduction of the groundbreaking Pixels-to-Points tool (Low Cost Photogrammetry Solution) which can Generate Point Cloud from drone imagery. This powerful addition to the Module allows anyone collecting aerial images with embedded geotags, such as drone or UAV operators, drone survey data to create a high-density point cloud, similar to LiDAR data. Using the additional functionality of the Module, this point cloud can subsequently be processed to identify and reclassify ground, buildings, and other common classification types and to filter and edit the data as required.

Global Mapper Pro features

  • Pixels-to-Points tool for creating a high density point cloud from overlapping imagery
