LiDAR Module

Latest Changes

New in v17.2

  • Significantly reduced memory requirements and increased draw speeds for Lidar point clouds loaded from text-based formats (i.e. .ply, .xyzi, etc.) as well as MrSID Lidar formats
  • New option to reset existing noise points to unclassified prior to performing an automatic Lidar noise classification
  • Sped up LiDAR gridding, classification, and extraction operations, particularly in low-memory situations in the 32-bit version

New in v17.1

  • New Custom Feature Extraction Tool including ability to manually select a series of points as part of a custom area or line feature for extracting it to a custom geometry. Feature vertices are placed while cycling through the profile views resulting in precise 3D line or area features such as road edge and curb lines, powerlines, and buildings
  • New Toolbar button for quickly and easily assigning the Ground classification to selected points
  • Added support for editing which classification groups a Lidar class belongs to

New in v17

  • Added support for automatically classifying power lines and above-ground utility cables
  • Expanded feature extraction to include the creation of line features representing power lines
  • Added option to detect and reclassify or delete noise points
  • Dramatically sped up nearly all Lidar operations, including load and display. In some cases operations will be 10 times faster or even more
  • Updated the filter dialog for Lidar to allow filtering by intensity, height-above-ground, NDVI and NDWI (when available), and return type in addition to the filter settings that were already there
  • Improved the speed of calculation and display of filled gaps when doing a binned grid of Lidar points

New in v16.2

  • Added support for Lidar with NIR (near infrared) sensor data. The new functionality makes use of 4-band RGB+NIR LAS files
  • Added support for NIR (near-infrared) data for Lidar point clouds. This includes new draw modes for CIR (color infrared), NDVI, and NDWI display, export to new LAS files with the NIR channel included, improved automatic classification of high vegetation/buildings using NDVI/NDWI, and gridding the calculated NDVI and NDWI values for the NIR-enabled Lidar

New in v16.1

  • Numerous improvements to LiDAR Module analysis features such as automated building and vegetation classification, feature extraction, and building height calculations for more streamlined processing and improved output
  • New support for the ZFS (Zoller+Frohlich) LiDAR format

New in v16.0

  • The ability to automatically classify building and trees
  • Feature extraction to render building and trees
  • Filter LiDAR points by class, elevation, color, scan-angle and source-ID when exporting, gridding, and selecting from point clouds
  • Dramatically improved automatic classification of ground points
    • Improved classification to filter out likely buildings and trees and added parameters controls to the ground classify dialog
    • Faster automatic classification of ground points for machines with multiple cores
    • Perform automatic classification on just selected points to speed up processing
  • Support for filtering LiDAR LAS/LAZ when exporting, filter by elevation range, color, allowed classes, angle range, and/or within a list of point source IDs
  • Support for filtering LiDAR point clouds when gridding, filter by elevation range, color, allowed classes, angle range, and/or within a list of point source IDs
  • Support for gridding LiDAR intensity or height above ground values rather than elevation
  • Enhanced option to filter the selected LiDAR points with the Digitizer Tool as well as an added option to filter the selection by classification, point source ID, and scan angle range
  • Support for coloring LiDAR point clouds by the difference in return values
  • Added right-click option for the Line of Sight Function in the Path Profile Tool to set the corridor width
  • New scripting commands for automatically classifying building and high vegetation using the LIDAR_CLASSIFY script command

New in v15.2

  • Support for transforming (shift/rotate/scale) of LiDAR point clouds
  • New LIDAR_CLASSIFY script command for classifying ground points in a script
  • Keep the original file offset/scale or specify a new one when exporting to LiDAR LAS/LAZ files
  • Crop to a selected area when specifying the bounds to import from a LiDAR point cloud
  • Export point clouds to Esri File Geodatabases (GDB) as normal 3D point features

New in v15.1

  • Added additional selection option on path profile dialog with LiDAR points shown to select by drawing a polygon.
  • Added support for loading Leica PTS point cloud files.
  • Added option when batch converting to LiDAR LAS/LAZ files to apply color from loaded imagery.

New in v15

  • Introduction of the New LiDAR module with advanced LiDAR analysis functionality. The licensing is handled under a new Help menu option for working with module and feature extension licenses. Visit our purchasing page for more info.
