Comment (by helena):

 Replying to [ticket:742 stevensj]:
 > Often LiDAR data is collected as strips (e.g. airborne), or point clouds
 with different sources (e.g. ground-based).  When the two files are
 combined they might be slightly offset, resulting in nasty artefacts.  It
 would be excellent to have a module that would allow one point cloud to be
 adjusted to best fit another one.  The same module would also be able to
 pin a dataset to ground control points.
 ....

 We have just started to look into this - we have ground based laser
 scanner and we need to co-register  multiple scans in 3D and we also work
 with a lot of airborne data (although the newest data usually come
 gereferenced pretty accurately). Please email me (hmitaso at
 unity.ncsu.edu) so that we can exchange more details about the potential
 module and the best methods for the task.
