[pdal] Generation of tiff file stops half-way

[Peter Lim]

Hi Andrew,

 

Using pdal info also gives the same output message.  

 

Anyway for Pdal to output what could be the possible errors in the laz file..

 

 

Thank you.

 

Best Regards,

Perhaps there's something wrong with the input? Perhaps you should use lasinfo or pdal info to check the file as a start.

 

Good luck,

Hi,

When I use Pdal to generate a tiff file from a laz file using the following Json: 

[

    {

        "type":"readers.las",

        "filename":"somefile.laz"

    },

                                {

                                                "type":"writers.gdal",

                                                "resolution":0.04,

                                                "data_type":"uint16",

                                                "output_type":"mean",

                                                "dimension":"Intensity",

                                                "gdalopts":"COMPRESS=DEFLATE,ZLEVEL=9,NUM_THREADS=10000,TILED=YES",               

                                                "filename":"compressed/CR_03C_BS, Tile 0168.tif"

                                }                              

]

 

I have the following message:

 

proj_create_from_database: datum not found

proj_create_from_database: ellipsoid not found

proj_create_from_database: prime meridian not found

proj_create_from_database: datum not found

proj_create_from_database: ellipsoid not found

proj_create_from_database: prime meridian not found

PDAL: readers.las: reading point 50000 of 176406445 total points 

 

and Pdal just stops half-way.

 

No tif file is generated.  May I know what is the issue…

 

 

Thank you.

 

Best Regards,
