What Is a Point Cloud?
Understanding LiDAR Point Clouds
A point cloud is a collection of millions of individual spatial measurements representing real-world surfaces and objects.
Each point contains precise positional information and may also contain:
-
Elevation values
-
Intensity information
-
RGB color data
-
Classification data
Point clouds are generated using technologies such as:
-
Aerial LiDAR
-
Terrestrial LiDAR
-
Mobile mapping
-
Photogrammetry
How LiDAR Creates Point Clouds
LiDAR sensors emit laser pulses and measure the time required for each pulse to return to the sensor.
Millions of these measurements are combined to create dense 3D point clouds representing:
-
Terrain
-
Vegetation
-
Structures
-
Utilities
-
Infrastructure
At SKYMAPTEK, aerial LiDAR workflows generate highly detailed point clouds suitable for engineering and geospatial applications.
What Can Be Created from a Point Cloud?
Point clouds are often processed into:
-
Terrain models
-
Surface models
-
Contours
-
Breaklines
-
CAD linework
-
Stockpile calculations
-
Volumetric analysis
-
Orthomosaics
-
Engineering-ready deliverables
Why Point Clouds Are Valuable
Traditional survey methods often collect limited spot elevations.
LiDAR point clouds provide millions of measurements across entire project sites, offering substantially more detail and site visibility.
This data can improve:
-
Design workflows
-
Earthwork analysis
-
Construction monitoring
-
Terrain modeling
-
Site planning
-
Quantity calculations
Point Cloud Processing
Processing raw LiDAR data requires advanced software workflows including:
-
GNSS correction
-
Point cloud classification
-
Terrain extraction
-
Surface generation
-
Quality control
-
CAD integration
