[gdal-dev] How to determine which creation options are supported by a driver?

[Rahkonen Jukka]

Hi,

Run ”gdalinfo –format GTiff”.  For me it prints:
<Option name="COMPRESS" type="string-select">
    <Value>NONE</Value>
    <Value>LZW</Value>
    <Value>PACKBITS</Value>
    <Value>JPEG</Value>
    <Value>CCITTRLE</Value>
    <Value>CCITTFAX3</Value>
    <Value>CCITTFAX4</Value>
    <Value>DEFLATE</Value>
    <Value>ZSTD</Value>
  </Option>

So my GDAL build does not support LERC.

Aihe: [gdal-dev] How to determine which creation options are supported by a driver?

Hi,

I have gdal 3.8.1 installed via Brew which includes liblerc and zstd as part of their formulae, so I assumed I could use the creation options “COMPRESS=LERC_ZSTD” and “MAX_Z_ERROR=x” as documented on the GTIFF page when creating a new gtif image.

But when I do GDAL states:

“Warning 6: 'LERC_ZSTD' is an unexpected value for COMPRESS creation option of type string-select.
Warning 6: driver GTiff does not support creation option MAX_Z_ERROR”

So I am not sure if this is an issue with the driver itself or with the brew formula.  Please advise,

Thanks,
Jesse
