Question

I have a *.LAS file, I want to transform it to ASCII ....file which contains the coordinates of the points, organised in one line per point. The coordinates are separated per spaces or tabs. Any thoughts?

Make sure to add the PointCloudCoercer - I missed that on my initial reply.

And depending on the size of your point cloud - you may be creating millions of points...

a bit complicated

 

 

transform my *.LAS file into an ASCII file (like the one attached)cube.pdf ... to open it in a software called DSE to extract discontinuities from a rock face...

Yo can set the Character encoding in the parameters.

 

The output will be a text file (with default extension xyz).

You could add the PointCloudThinner in before the Coercer... or you might want to look at thinning the points afterwards...
