Edit global shift and scale by command line

Post by PSpohn »

Hello everyone

I have many LAS files which are stored in a local system (global shift = 0.0 0.0 0.0). I need to shift them to a global system like UTM32 (global shift = 32512000 5845000 0.0).

Is there a way to edit the global shift in command line mode, like you can do it in CC directly?

Maybe like: -SET_GLOBAL_SHIFT -32512000 -5845000 0.0

I tried to use the "-APPLY_TRANS" command. But since the shift is too far, I ran into coordinate accuracy problems because of the internal storage as 32 bit float values for the coordinates.

Hum, good point. Sadly I don't think there's any way to do it yet! That's something we should think about, I'll add this to the TOOD list.

"-O -GLOBAL_SHIFT"

-GLOBAL_SHIFT is different, as it will shift the coordinate (values) before storing them in memory. Here @PSpohn will need to virtually change the global shift, so that the points are changed at export time only...
