LiDAR Point Cloud Viewer

Online LAS Viewer (3D Point Cloud)

Upload your LiDAR point cloud; color it by RGB, elevation, intensity or classification and explore it in 3D right in your browser.

Left drag: rotate · Right drag: pan · Wheel: zoom

Upload a .las file below;
the point cloud will appear here in 3D.

Drag your LAS file here, or click

Uncompressed .las files are supported (LAZ not yet)

Your Data Stays in the Browser

Uploaded LAS files are parsed in your browser and rendered with WebGL; nothing is sent to any server. Everything happens on your device.

Online LAS Point Cloud Viewer

What are LAS and LAZ?

LAS (LASer) is the industry-standard binary format defined by ASPRS for storing point cloud data captured by LiDAR scanning systems. Each point carries a position (X, Y, Z), intensity, classification and often RGB color. LAZ is the losslessly compressed version of LAS. The tool reads LAS versions 1.0 to 1.4 with point record formats 0 to 3 and 6 to 8; compressed LAZ files are not supported yet.

  • 3D viewing: Explore the point cloud by rotating, panning and zooming.
  • Coloring: Paint by RGB, elevation, intensity or ASPRS classification.
  • Privacy: Your files are processed in the browser, never uploaded.

How to use it

Upload or drag-and-drop your LAS file. The point cloud opens automatically in a 3D view. Use the panel on the right to change the coloring mode and point size, and "Reset view" to return to the starting angle.

Frequently Asked Questions

What is the difference between LAS and LAZ?

LAS is the industry-standard binary file format for LiDAR point cloud data (defined by ASPRS). LAZ is the losslessly compressed version of LAS, storing the same data in a much smaller file. For now this tool opens only uncompressed LAS files; a LAZ file has to be decompressed to LAS first.

Are my files uploaded to a server?

No. Your LAS file is parsed entirely in your browser (on your device) and rendered with WebGL. The file is never sent to any server.

Can it open very large LAS files?

Yes, but browser memory is limited. Very dense clouds (more than a few million points) are automatically thinned for performance; the total point count is shown in the info panel.
