A point cloud is a set of data points in a coordinate system. They can be the result of a laser scan and show the external surface of the scanned object. Point clouds can be stored and shared using Trimble Connect, the collaboration environment from Trimble.
To find out more, see the Point Clouds article on the forums in the Trimble Community.
The community is a great place to learn about point clouds, as well as many other things. You can also ask questions or talk to your peers.
