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

SKYMAPTEK utilizes professional geospatial processing workflows to generate accurate engineering-ready deliverables from aerial LiDAR datasets.
