I have two construction sites where the point cloud classification is really mixed up between road surface and ground. I.e road is classified as ground and ground is classified as road. Does this mix up between the two groups have any negative impact on the accuracy or ‘truthfulness’ of the contour lines or DTM?
It would be a painstaking job to reclassify everything manually so if it does not negatively impact the DTM or contour lines then I guess it’s not worth the trouble to reclassify. Unless it is really necessary.
