I use a program called SCENE that is associated with the terrestrial LIDAR scanner. I have about 80 comparisons dealing with bank erosion and deposition. Once I have processed the images in SCENE I then use CloudCompare to run the M3C2 algorithm that is needed to see changes. After running the algorithm, I then use the rasterization tool to export the associated active layer and then the associated heights of the scans. Of all the comparisons, 3 are showing strange height values. If the GPS data for one of the two comparison images is missing could this impact the results of the heights being exported, however, this has not impacted other scan height values. (As a few comparisons also have missing GPS data and their associated height values are correct).
Is Cloud able to alter height information or does it transform it in some way if all the required information it needs is unavailable?
In general, what values is Cloud using to get the heights that I export? (Altimeter, GPS?)
Also, would this missing information impact the algorithm?
