Today I noticed that the previously out-dated “Spatial Reference” coordinate registry website has been refactor to PROJ v9 thanks to Javier Jimenez Shaw.
website: https://Spatialreference.org
Pros - the IAU 2015 codes based on the Archinal et al., 2018 IAU report are available. These are the same codes standardized by the OGC, found in PROJ (thus GDAL, QGIS), and used in the latest version of GeoServer.
Cons - The older IAU2000 links are deprecated. You can still find them but if used you will be met with this new error
404
File not found
Sorry, iau2000 is not supported anymore. You can get old data from file
spatialreference.org/scripts/iau2000.json at master · OSGeo/spatialreference.org · GitHub
example uses:
- Mars (HTML): IAU_2015:49900 - WKT2 -- Spatial Reference
- Mars (programmatic WKT2): https://spatialreference.org/ref/iau_2015/49900/prettywkt2.txt
- Mars (programmatic WKT1): https://spatialreference.org/ref/iau_2015/49900/ogcwkt/
- Mars (programmatic Proj4, yes deprecated): https://spatialreference.org/ref/iau_2015/49900/proj4.txt

but you can also just do:
gdalsrsinfo IAU_2015:49900
