[pdal] Took long time to generate Geo-tiff file after Update to Pdal 2.1.0

[Peter Lim]

Hi,

 

I've recently updated the Pdal version to 2.1.0 (git_version: Release).  

 

It took about 40 hours to generate a geo-tiff file from a laz file with 23
million points 

using 64GB Ram and the following json commands:

[

    {

        "type":"readers.las",

        "filename":"somefile.laz"

    },

 

                                {

                                                "type":"writers.gdal",

                                                "resolution": 0.03,

                                                "data_type":"uint16",

                                                "output_type":"mean",

                                                "dimension":"Intensity",

 
"gdalopts":"COMPRESS=DEFLATE,ZLEVEL=9,NUM_THREADS=ALL_CPUS",            

                                                "filename":"somefile.tif"


                                                

                                }                              

]

 

Before the Pdal update, it used to take about 3 - 5 hours only

 

Any idea why was it taken such long time.

 

 

Thank you.

 

Best Regards,

 

Peter Lim
