LIDAR Accuracy ?

Good afternoon All,

Firstly, I can't believe I'm posting on the survey part of this forum, but since starting to use Kubla Cubed I've become fascinated with obtaining survey points and contours for all my cut and fill projects.
My question is, to all you land surveyor types is, how accurate do you find LIDAR data?
I've managed to find a way of converting the LIDAR data into xyz points then producing a dxf of the contours, chopping the resulting file to the required area of the site, then importing into Kubla Cubed.
It would be quite comforting to know if the data is reasonably accurate and suitable for estimating applications.

Cheers

Tim,

I have Lidar on my iphone.  I tried a couple times to get usable data.  One time the scan I did turned out upside down.  Is there a tool to make this work?  It seems like I get too many points of data even when I use the low res option, and the file is still too big.  Has anyone had success with lidar scanning?  Is there maybe a better app I can use.  I've tried Polycam and 3d Scanner App.

Thanks

Enoch
