Contour lines from big LIDAR data

Post by MagicBrou »

hey guys,

is there a software to produce contour lines of very big datasets from LIDAR? I have a Pointcloud with 120million Points.
I tried cloud compare and trimble realworks but always failes :(

You can do it easily enough with SCC, download here which will give you a 30 day trial license http://www.atlas-files.com/scc-users/se ... 3-27-6.exe 120 million points isn't that big, we're regularly working with point clouds in the billions of points. Depending on what you are contouring, you may also need to do some feature extraction for kerbs, break-lines etc... to get a good quality DTM from which to derive your contours. If you can send me a link to your data in an open format such as LAS, E57 or PTS, I'll capture you a short video of the process involved.

I used Rhino 3D to generate these contours from LIDAR data of the island where I live.
The pointcloud is about 110 million points.

Mike.

I use Cyclone 3DR, expensive but accurate.
Global Mapper by Blue Marble is very inexpensive but I've not tested it for accuracy in contour extraction.
Accuracy is key for my needs.
