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 houses are properly extruded where as trees were not extruded. I am wondering why this happens with Drone2Map. To clarify more: 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. But uninterestingly there is a forest area in my AOI in which NOT EVEN ONE TREE was 3D extruded, leading to a big confusion. 2. The images have 60% forward overlap and 40% lateral overlap, which is sufficient for stereo generation in a normal photogrammetric scenario. Is this a short coming in the processing algorithm? Because, I can not see any fault in the input images.

Have you tried processing the same set of images on two different machines: One for 2D product (orthomosaic) and another for 3D product (mesh)? Hope that saves the processing time considerably.

Hi Rosie, I am also facing a similar issue but one thing I can be sure that it is efficient to run maximum number of images with D2M than running with small chunks. From my experience, I can say that the D2M does not take much time in report generation but writing the output takes the considerable time.

How can I get complete bounding polygon of XS CutLines for flood plain mapping (Flood Inundation Mapping) using HEC-GeoRAS and ArcMap 10.3? When I tried to perform this task, the bounding polygon formed was in an unexpected manner: I want to get the bounding polygon without the gap that is visible around the river junction.
