Hi Roberto, I am not sure what is going on there. There haven’t been any chances to that code over the period you talk about. However, I think the difference is more likely to be with your input data. The spdmccgrd and spdpmfgrd commands do not try to classify vegetation or any other classes only ground but if returns have a classification before they are entered into spdmccgrd or spdpmfgrd then only the points which are classified at some point with the processing as ground are changed. In the final classification not all point may end up as ground, if they are only ground at an intermediate stage then those points will be assigned as unclassified. Therefore, you will commonly see quite a few unclassified returns near the ground.
If you want to test it or to ‘clean’ your data before using spdlib to classify it then you can use the spdclearclass command to assign all returns to the class ‘unclassified’. I hope that helps, let me know if it doesn’t make sense or this is not what you are seeing.
