i'm trying to extract a dem from a LiDAR multipoint. My method is to create a new field (bare earth elevation), and get values from calculate geometry of Minimum Z Value. I'm just wondering if I should explode the multipoint first, calculate my elevations before doing my interpolation????
i just dont know if the interpolation tools (e.g. IDW) are considering all of the 12 million points that i have, or just considering the multipoint set. (i'm just nervous because i have around 3000 multipoints and it's giving one elevation value for 1 multipoint that could contain around 3500 individual points...)
