What is a .LAS file?
LAS stores LiDAR point clouds from laser scanning and aerial surveys.
- Did you know
- The LAS format, standardised by ASPRS in 2003, is the industry standard for LiDAR data.
- LAS is a binary format from the American Society for Photogrammetry and Remote Sensing, with a public header, variable-length records and point data.
- LAS stores each point’s coordinates as 32-bit integers, applying a scale and offset from the header to recover the real positions.
- What Analyser reads
- Header and metadata extraction for 3D meshes, voxels, BIM, point clouds and Gaussian splats: Wavefront OBJ, Stanford PLY, OFF, glTF, AMF, MagicaVoxel VOX, COLLADA DAE/ZAE, USD crate, X3D/VRML, LightWave LWO/LWS, Quake MD2/MD3/MDL, VRM avatars, Siemens JT, LAS/LAZ/PCD/PTS/E57 LiDAR clouds, IFC BIM, and .splat/.spz - vertex/face/point counts, bounding boxes, units and authoring tool.
- Depth of analysis
- .LAS is an identification-grade format: Analyser recognises it from its bytes and decodes the header metadata it carries, rather than opening it in a full viewer. Formats that do get a full viewer are marked "Full" on the formats page.
- Open a .LAS file
- Drag a .LAS file onto the Analyser home page (or tap to pick one). It is identified entirely in your browser - nothing is uploaded, there is no account, and it works offline once installed.
