LiDAR — Light Detection and Ranging Reference#

Quick-reference skill for LiDAR technology, point cloud data processing, scanner configuration, and mapping applications.

When to Use#

• Processing point cloud data (LAS/LAZ/PCD formats)
• Configuring LiDAR scanners for survey or mapping
• Understanding scan patterns and coordinate systems
• Filtering, classifying, or visualizing point cloud data
• Choosing between airborne, terrestrial, and mobile LiDAR
