Hi Dominic, Well first it is important to not assume that it is easy to create a mesh from a point cloud. One of the biggest problem is the position of the scanner is not saved into the point cloud data file. Even worst is that often more than one surveyed point clouds is mixed into the same point cloud data file. Finally point cloud often contains a lot of noise (outlier points) which need to be removed. But in the end I guess it all depends on what you are trying to achieve. Mesh created from picture precision is about the pixel size of the picture. So close-up pictures would be able to give you good precision. HTH, Mathieu
