Hi Jochen, it would be nice to be able to use lacopy with xy and z. 
exemple: lacopy64 -i mylassource -i maylastarget -xy 0.5 -z 0.01 -o mynewlas
Kind regards from Cambodia

Hi David,
you can use lascopy64 with arguments -match_xyz 0.5
If you want to have different from xy values for z it is probably easiest to scale z before to the same dimension like xy, do the copy and then scale back:

las2las64 .... -scale_z 50
lascopy64 ... -match_xyz 0.5
las2las64 ... -scale_z 0.02

Cheers,

Hi, effectively this is a way of doing it, but it adds 2 scripts and thus will increase processing time. 
It would be nice in a future version to be able to get a different size for the planimetry and for the altimetry,
exactly like las3dpoly.

Hi David,
we implemented this request.
You can now use the lascopy64 argument with 1 argument or with 3 arguments for xyz distance.

-match_xyz [dx] <[y] [z]> : Match points by x-y-z coordinates and a spherical distance [dx] or a bounding box [dx] [y] [z]. 

Please find a pre-release for Windows and Linux here:


Until otherwise noticed this will be part of the next official release.

Cheers,

Jochen @rapidlasso
