The Esri zLAS I/O library is a C++ runtime library that provides API access for reading and writing Esri Optimized LAS (*.zlas) format files as well as converting between zLAS and LAS. It is out of beta and available to the general public in final form.
- Convert zLAS files into LAS files. LAS is an ASPRS industry standard format for lidar data.
- Convert LAS files into zLAS files.
- Read zLAS into memory buffers as LAS formatted data (e.g., header record, point data records).
- Read zLAS into structs for easy interpretation of LAS information.
