greetings my dears; I hope you are in good health;
The case is, my goal is to build a DTM; The dense cloud had more than 6 billion points, so to be able to classify the dense cloud, I had to split the chunk into three since with my RAM memory I can only classify about 2.5 billion points.
After classifying each chunk, I tried to build the DTM for each chunk, with active interpolation, the DTM covered the entire area, that is, it includes the area where I deleted the dense points (note that I compacted the point cloud). So I tried to merge the chunks (only the dense clouds), but when I look at the result I notice that the resulting cloud is not classified; Is there any solution for this case? I'm using Metashape 1.7.3
