topic Drone2Map: Trees are not extruded in 3D mesh. Why? in ArcGIS Drone2Map Questions https://community.esri.com/t5/arcgis-drone2map-questions/drone2map-trees-are-not-extruded-in-3d-mesh-why/m-p/346725#M705 <HTML><HEAD></HEAD><BODY><P>I have been trying to generate 3D mesh in Drone2Map but the major issue I am facing is that the trees in the image are not extruded into 3D. This is so peculiar that all the shrubs and&nbsp;houses are properly extruded where as trees were not extruded. I am wondering why this happens with Drone2Map.</P><P></P><P>To clarify more:</P><P></P><P>1. I have tried with different parameter combinations in the D2M image processing window but somehow I managed to get a maximum of 50% trees extruded in the study area, with a final optimal parameter combination.

The images have 60% forward overlap and 40% lateral overlap, which is sufficient for stereo generation in a normal photogrammetric scenario.</P><P></P><P>Is this a short coming in the&nbsp;processing algorithm?
