<p class="MsoNormal"><span lang="EN-US">Hi,<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">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. <o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">But when I do GDAL states:<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">“Warning 6: 'LERC_ZSTD' is an unexpected value for COMPRESS creation option of type string-select.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">Warning 6: driver GTiff does not support creation option MAX_Z_ERROR”<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">So I am not sure if this is an issue with the driver itself or with the brew formula. Please advise,<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">Thanks,<o:p></o:p></span></p>
