The Matanuska-Susitna Borough's 2011 LiDAR & Imagery Project has been around for a while now, but I recently discovered that the Point MacKenzie data on the public mirror has been made available as compressed LAZ. The LASzip format is not ideal for all purposes, but it is always a major improvement when data servers provide data in LAZ format because of the massive reduction in bandwidth and download times.
Even when CloudAE did not support LAZ directly, it was always well worth it to download the compressed data and convert it to LAS. Now that CloudAE supports LAZ, everything is much simpler.
