 Intensity is digitised at either 1 or 2 nano seconds with either 256, 128 or 64 samples recorded. [[BR]]
+ns represents 15cm/256 samples --> max. collection of 38.4 meters (25615cm). [[BR]]
+If it is known that the height is under 19 meters, then can change to a lower sampling rate (128@1ns --> 19.2m or 256@2ns --> 19.2m)
+ns represents 15cm/256 samples --> max. collection of 38.4 meters (256*15cm). [[BR]]

+If it is known that the height is under 19 meters, then can change to a lower sampling rate (128@1ns or 256@2ns).[[BR]]
+If flying over flat(ish) terrain, then can reduce to a lower sample depth without loss of useful information.
