Use this dialog to import point cloud data to point cloud objects in application layers.

Where do I find the dialog?

In the properties dialog for application layers, select the Import/export tab and click Import... under Laser scan formats (point cloud)

The import function supports the following formats:

  • LAS/LAZ files - Standard laser scan format
  • Leica database (DBX) - Leica proprietary format
  • PTS files (Leica) - Leica point cloud format
  • E57 files - ASTM E57 standard

Import options

Colors and intensity

Available data

  • LAS/LAZ, PTS and E57: Can import colors (RGB) and/or intensity
  • DBX database: Only intensity available (no color information stored)

Classification (LAS format)

Classification functions

  • Split by classification: One point cloud for each class

Area delimitation

You can clip the data against a defined area with "Exclude objects outside".

Manual coordinate input

The coordinates for the area must be entered manually before import.

Detailed format information

PTS files

Gemini Terrain can import:

  • X, Y, Z coordinates
  • Color (RGB)
  • Intensity

Leica database (DBX)

Gemini Terrain can import:

  • X, Y, Z coordinates
  • Intensity

LAS/LAZ format

Standard laser scan format

LAS/LAZ is a standard format for software that combines GPS, IMU and laser scanner to produce X, Y and Z data.

Importable data elements:

  • X, Y, Z coordinates
  • Classification
  • Color (Red, Green, Blue)
  • Intensity

Classified data

  • Data is usually delivered pre-classified
  • Use Split by classification to get one point cloud object for each class in the application layer
