Subject matter is a group of buildings and surrounding landscape in about a 20 acre area. Objective is to get good modeling of buildings and a bit lesser so with the surrounding landscape. Also need to generate a DEM+contours for the surrounding undeveloped landscape. My plan is to do an Enhanced 3D Mission (Crosshatch + Perimeter) for the entire site and then a bit lower altitude in a smaller area just around the group of buildings. I’ve always noticed the “Enhanced 3D” mode just includes crosshatch and perimeter flights, no nadir flights. It also defaults to 60/60 overlap.
Does this mean if you run Enhanced 3D also doing a nadir mission doesn’t provide a significant enough benefit to make it worthwhile? If so, if only using Enhanced 3D for modeling buildings, should the overlap be increased? Or would a better quality model be achieved from combining the Enhanced 3D at 60/60 overlap with a nadir mission at say 70 sidelap, 80 frontlap?
