[Liblas-devel] Remove an SRS using LibLas

[Brady Callahan]

Thanks Howard,

The following is definitely the functionality that I'm after

las2las --a_srs "" srs.las output.las

so I'll look forward to seeing it in an upcoming release!

You could always do this through the C++/C/Python APIs, but not through las2las.  You can use the --a_srs switch in las2las to assign a new SRS to the outputted file (which is what I think you might be referring to), but if you set it to an empty string, it would complain.  I have fixed this for the next beta.  It will now be possible to do:

las2las --a_srs "" srs.las output.las

and have output.las end up with no coordinate system attached.

Thanks for the feedback!
