OBJ global positioning not correct
Posted: Mon Oct 21, 2024 4:30 pm
Hi,
I know I HAVE to be doing something wrong, so I thought it best to post what I'm doing and what I'm trying to achieve - all help greatly appreciated!
I have a LAS file (in CRS EPSG:27700), which when I import to CC I get the global shift/scale window which states
shift of --627000.00, -231000.00, 0.00 and scale of 1. (The preserve global shift on save is ticked)
Thats fine, I import it in, compute normals, apply PossionRecon to mesh it and then export as an OBJ
However, when I load my OBJ into Cesium, its positioned at 49.79650021969205 , -7.565011240063517 (Lat/Long), but I expected it to be 51.937229 , 1.3132739.
I assumed on export that it would've kept the original coordinates? What am I doing wrong that it's being misplaced?
