Having previously taken a comparison (signed difference) between a layer of LAS LiDAR points in NAVD88 and the same points transformed (using VDatum) to MLLW, visually the average value of that difference appears to be about 1.795m ±0.002m. It doesn't seem possible to obtain a more precise value from Global Mapper, or am I missing something?


Thank you very much.
