Hello Adam,
lasoverage is fully functional in the version that is online - except for the black diagonal lines that are added to the output raster. However, these only minimally affect your ability to judge the quality of the flight line alignment but let you evaluate the speed and efficiency of using LAStools for quality checking.
The GPS time is not being used for lasoverlap. For lasoverlap it is important that an adequate step size is used and that the input contains correct populated point source ID fields. If the input is a set of flight lines this means that the option ‘-files_are_flightlines’ needs to be set. Then there will be one single output raster. If the input are already tiled flightlines then each point must indicate which flight line it is from with a flight line unique point source ID. Then there will be one ouput raster per tile (unless ‘-merged’ was specified).
Any issues with lasoverlap are to be blamed either on user error or on poor documentation. (-:
Regards,
Martin

I am still playing with the trial version until commercial license is finalised… Should I expect lasoverage to be totally broken until the commercial version is used? I remember seeing something about GPS time being butchered on trial version?
If you could confirm that it should be working in the trial version I will persist and perhaps follow up with a detailed outline of the issues I am having.
Thanks.
