Does to_wkt use PROJ version to determine WKT version to use?

See original GitHub issue

I’m in the process of converting the pyresample project to use WKT internally by calling CRS.to_wkt(). We’ve had issues in the past with other projects where we would pass pyproj.CRS.to_wkt() to rasterio’s CRS object. Rasterio seemed to depend on the version of GDAL installed (GDAL 3 -> WKT2 supported, otherwise WKT1). So I’m wondering, does pyproj’s support of WKT2 depend on the version of PROJ? Is there ever a chance for a user to install current pyproj with an old-ish PROJ and get errors when to_wkt tries to convert to WKT2?

Great.pyproj >= 2.3 is probably what pyresample will require so this looks good. Thanks again.

Is it coded in pyproj or does it come from PROJ?

It comes from PROJ

Does the minimum version of PROJ required by pyproj support WKT2 so this could never happen?

Correct
