Reproject (horizontal and vertical)? #340

Closed jgrn307 closed 4 years ago

I was curious if there is a way to convert LAS points between horizontal and vertical datums? We've got some data that is NAD83 and needs to be tweaked to NAVD88.

I don't think so. The tool for projection available is only a wrapper around sp::spTransform. It reprojects xy leaving z unmodified. If sp is capable of such transformation I guess lidR too. But anyway I really do not recommend to use R for that. Use las2las from LAStools instead.
