Remove Ground Contours and Objects such as trees or buildings

Hey guys can anyone assist me on how to remove contour lines for tress or buildings from a generated contour maps?


You will need to be on a plan that includes DTM. many CAD programs can do this as well. My recommendation would be Carlson precision 3D topo if you are doing this for business.

Has there been any new tools/services (cheaper!) that have cropped up in the last couple years?

I’d also like to be able to remove trees so that the terrain can be imagined/planned as more of a blank slate.

My client doesn’t want to remove any (or perhaps very few) actual trees, just have a better view of the land itself.


Yeah, unfortunately DroneDeploy’s DTM’s can be insuffient and they have problems with objects as the get larger. We use Carlson Precision 3D Topo. There is also Recap if you have it but it is a manual process and can potentially degrade the quality when it gets exported back out for Civil 3D or other CAD program. QGIS can do it but it will take some perseverance.
