LAS stores LiDAR point-cloud data captured by laser scanners on planes or drones to build 3D terrain. The viewer reads the points, including supported colour fields, and shows them as an interactive 3D cloud.

What is a LAS file?
LAS stores LiDAR point-cloud data captured by laser scanners on planes or drones to build 3D terrain. The viewer reads the points, including supported colour fields, and shows them as an interactive 3D cloud. The .LAS extension identifies a LASer point cloud file, which is served with the application/vnd.las media type. You can open it here instantly — drop the file into the box above and it renders in your browser. Nothing is uploaded.
Besides this free online viewer, you can open LiDAR (LAS) files in desktop apps such as CloudCompare, QGIS, Potree — but here all you need is a web browser.
