Hello:
I am trying to change the vertical datum of a LIDAR LAS file. But
first I must understand the syntax of proj, but I can't understand it.
If I use the following expression:
echo 747194.732 2307402.892 2037.133 | proj +proj=vgridshift
+grids=C:/clouds/geoids/GGM10_GEO.gtx
"proj" is a legacy tool only for 2D cartographic projections. You want
to use cct instead: https://proj.org/en/9.4/apps/cct.html

My software is free, but my time generally not.
