Amazon have released the USGS 3DEP data set, which is Lidar point cloud data covering the USA. It’s in a “requester pays bucket” which apparently means that you have to pay a fee to cover the cost of the network download. I guess that means opening some sort of Amazon account. Well it is a huge amount of data and somebody has to pay for the network traffic.

On the same subject, the UK Environment agency offer free downloads of UK Lidar data and they aimed to have complete coverage of England by the end of 2018, plus most of Scotland and Wales, so we should be there by now. The whole of those countries should follow in the future.
