Point Cloud Styling

Point cloud layers (LAS/LAZ files) display millions of 3D surveyed points. The style editor controls how points are coloured and which classification types are visible.

Colour mode

Mode	Description
From Data	Use the colour values embedded in the point cloud file (RGB)
By Class	Colour each point by its LAS classification class. Click any class to change its colour. Click Reset to restore default colours
Intensity	Colour by return intensity value. Adjust the max intensity slider to control the brightness range
Solid Color	Single solid colour for all points

Classification filter

When using By Class colour mode, you can show or hide specific LAS classification types:

Class	Examples
Never classified	Points the classifier did not process
Unclassified	Points not yet assigned a class
Ground	Bare earth, roads
Low / Medium / High Vegetation	Grass, shrubs, trees
Building	Rooftops, structures
Low Noise	Measurement errors, outlier points
Model Key	Key points used to build the surface model
Water	Lakes, rivers
Rail	Railway tracks
Road Surface	Paved roads

Use the All and None buttons to quickly select or deselect all classes. If your dataset uses additional classification codes, use Add class to add them to the list.

tip

Hide vegetation and noise classes to get a cleaner view of buildings and ground surfaces. This is especially useful for urban planning analysis.

Point size

Adjust the point size from 1 to 10 pixels. Larger points fill gaps but can obscure detail at close range.
