What is a LAS file?
A .LAS file usually contains 3D point cloud data. The American Society for Photogrammetry and Remote Sensing (ASPRS) created this format. It is known as a LIDAR Data Exchange File. Professionals use it to store 3D laser scans of the earth, terrain, and buildings.
However, a .LAS file can also be a Log ASCII Standard file. The Canadian Well Logging Society created this format to store geological well log data in plain text.
Because the .LAS extension has multiple meanings, you can use viewer.online/las to identify the actual format of your file.
How to open LAS files?
If your file is a LIDAR Data Exchange File, you can open it with LAStools, CloudCompare, or GIS software like ArcGIS and QGIS. If your file is a Log ASCII Standard file, you need specialized oil and gas software like JewelSuite or OpenWorks.
Because these files often require large or expensive software, viewer.online/las can analyze .LAS files to identify the exact format and creator software. It allows you to inspect the file structure, extract readable text, and check whether an online preview is available.
Converting LAS files
If you need to use the data in other software, you might need a different format. For example, you can convert LIDAR .LAS files to compressed .LAZ files or readable .XYZ formats. For reliable conversions, we recommend using convert.guru.
Summary
viewer.online/las is useful for identifying, inspecting, and understanding .LAS files without installing software or dealing with compatibility problems. It helps you quickly verify if your file is a 3D LIDAR scan or a geological text file.
