Hi, Anna,

   I don't know if the original las files are available; I'll ask the agency
for them (and I have a las compression library that reduces storage volume
for the .las files.)

   As I'm learning about LiDAR data I've no idea what I need in terms of
processing. These data are quite different from the 10m DEMs I've used for

   OK, then, nothing significant has changed external to the modules.

Thanks very much,
