I have been rasterizing some las files and found something odd. All my geoTiffs have a lot of pixels that are defaulting to min height value - despite me setting options otherwise. Basically it seems that if a GeoTiff pixel doesn't have any Lidar sample points that fall within it, it gets assigned m...

Updating point cloud with GeoReference system

I’m really new to CloudCompare (and georeferencing n general) so forgive me if this is a simple question. We have a pointcloud scanned using the cameras local coordinate system. Afterwards we got GPS positions for the area corners and would like to update the pointcloud with that. In other words, sw...
