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
years.

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

Thanks very much,
