When I fly with LIDAR each flight has overlaps at the edges, and additional sidelap, which results in overlapping points where the flight lines come together. Is there a way to filter the points so the density is consistent right across the point cloud?

This is what the data should look like inside a PRJ file:

GEOGCS["GCS_WGS_1984",DATUM["D_WGS_1984",SPHEROID["WGS_1984",6378137,298.257223563]],PRIMEM["Greenwich",0],UNIT["Degree",0.017453292519943295]]

PRJ contains the projection data to allow the exported file to be overlaid on other projected data, e.g. in Google Earth or an ESRI platform. Without it, shape files are pretty useless.

I did as you suggest for the contours Daniel, but the SHP file set is missing the PRJ file so cannot be used. Do you have any idea what I'm missing that would cause this? The original point cloud is georeferenced but I think this gets removed when you open it in CC? How do you restore the georeferen...

I hope you will excuse a newbie dumb question, but I am struggling to get meaningful exports from CloudCompare. I was able to import 4 Lidar point clouds, merge them together, crop to an area of interest, classify to ground and generate contours, very easy and straightforward. But what I need to do ...
