LASzip – Lossless Compression for LAS

Martin Isenburg presented this paper at ELMF this week on LASzip –  a software technology that he has recently developed for compressing LAS files.

Borrowing from the  paper abstract, “We describe a completely lossless compression scheme for LiDAR in binary LAS format versions 1.0 to 1.3. Our encoding and decoding speeds are around one to three millions points per second and our compressed files are only 7 to 25 percent of the original file size.

Sounds very impressive. Looks like the ASTM E57.04 Data Interoperability subcommittee is going to tackle compression next. We can use your input on the importance of adding this to the standard.

  1. Here is a video of my talk at ELMF on “LASzip: lossless compression of LiDAR data”.
