LASInfo64 repairs, delete_empty and cores

[ncwil...@gmail.com]

I've found a few things with lasinfo with the following script I have been trying to get working. 

For some context, the input for this would be tiles I get out of running lastile with an external tiling shapefile. The goal is to delete the empty las files and repair counters and bounding boxes. Here is my script:

lasinfo64 -i %INPUT_FOLDER%\*.las -repair -delete_empty -cores %NUM_CORES%

I noticed the following

• It appears to be deleting empty LAS files, but not running the repair switch. Are these two switches not compatible to be run in a single lasinfo call?
• I tried running without -delete_empty and the repair switch works, but the 64 bit lasinfo does not run with multiple cores. 32 bit lasinfo does use multiple cores with repair.

Hi,

(a) you have to run -repair and -delete_empty in 2 steps

(b) repair works good to repair the header boundaries. If the reader tries to read behind the data it maybe fail, both, the 32 and 64 bit version. But: The 64 bit version has a new error handling. If a read error on one file occur, the program stops. To force to continue on (read) errors you have to use '-errors_ignore'.

   lasinfo64 -i %INPUT_FOLDER%\*.las -repair -delete_empty -cores %NUM_CORES%  -errors_ignore

will lead into the same behavior than the old version.

Cheers,
