LIDAR Point Cloud Sources

Best sources for free LIDAR point clouds (probably LAS or LAZ format):

For MICRODEM, the data must be in UTM or geographic coordinates. There are options to reproject with MICRODEM, liblas, or LAStools. LAS lidar

General caveats:

May need to get LAStools to
- reproject data if it is not UTM
- uncompress LAZ data if that is what you get
MICRODEM will identify each project area by the name of the directory. You should put the files for each project in a separate directory, and give it a short, meaningful name

Source and directions	Web site	Notes
OpenTopography	http://www.opentopography.org/	Mostly US, but now a lot of data from New Zealand. If you have an edu email, you can get USGS lidar.
NOAA Coastal Lidar	Graphical: http://coast.noaa.gov/dataviewer/?# (Flash required) Projects list: http://coast.noaa.gov/dataviewer/?dataregistry/#/coastallidar Getting lots of data	Some surveys may penetrate water; others only coastal strips of land. For many areas several dates are available, showing temporal change.
