Hi Martin,
Esri's reference below: https://github.com/Esri/esri-zlas-io-library
states that the esri-zlas-io-library read/writes Optimized LAS, and is
also Open Source, under the Apache license.
Does this mean that it is possible to reverse engineer the Optimized LAS
format?
Would this open the possibility to integrate LASzip and Optimized LAS?
Thoughts?
Regards Cameron.
