[pdal] assign projection info without creating new file

[Matt Beckley]

Hello All,

I have thousands of .laz files that have no projection information.  From
my contact, I received the EPSG codes for the datasets.  I can apply them
with a pipeline such as:

{

    "pipeline": [

        {

            "type" : "readers.las",

               "filename": "input.laz"

           },

        {

            "type" : "writers.las",

               "filename": "output.laz",

            "a_srs": "EPSG:2193+7839"

           }

    ]

}


I suppose I could just then do  "mv output.laz input.laz" in a bash script
to end up with a single file with the proper projection in the header.

My question: Is there a way I can do it without creating an intermediary
file?  I tried the obvious of reading and writing to input.laz, but that
didn't work.  With thousands of files, it seems like it could save some
time.  Just curious.

Thanks,

matt.
