IMPLEMENTATION
Viewers responsible for this format
LAS is a binary exchange format for LiDAR point clouds. Its header describes the point layout and the scale and offset used to reconstruct coordinates. Anyfile reads supported LAS 1.0–1.4 records in chunks and displays their positions, making it useful for a quick check of a survey's overall shape.
Common question
Why is my LAS cloud missing classification colors?
The current preview uses positions only. A LAS file can store additional attributes, but this viewport does not color or filter points by ground class, intensity or return.
Should I use the LAS or LAZ page?
LAS is uncompressed; LAZ adds point-data compression. Use the matching file directly. The LAZ reader has a smaller compressed-input limit because it loads that input into memory.
