Best WorkFlow or Software for DSM/DTM Filtering

Hi All.

We are a aerial/land surveying firm here in Jamaica, and been using Pix4D/AutoCad work flow for terrain contour/topo mapping. We are looking for the best solution for DSM auto classification specifically of building, trees, and ground for ground based topo mapping. Anyone care to share their work flow or software solution?

There are three different programs I have used with good success. Global Mapper with the Lidar model (an iterative process). VG4D UAV explorer (real time editing) and LP 360 which is the top of the line. P4d is getting there, but it may be awhile before they catch up. If I was looking for production, LP360 would be my choice.
