Hello @twhiteaker I am wary of the reference you have provided for this CRS definition. https://epsg.io/3408
The WKT provided appears not conformant to the CRS WKT standard. There are syntax issues suggesting this may have been manufactured a long time ago. I'm not convinced it is valid syntax. Searching for EASE suggests that http://www.epsg-registry.org/export.htm?wkt=urn:ogc:def:crs:EPSG::6931 may be the definition in this case, but I do not know enough about the EASE grid definitions to understand if this is the case. The definition in the registry suggests that this is an updated version of 3408: ``` WGS 84 / NSIDC EASE-Grid 2.0 North | EPSG::6931 | ProjectedCRS | Valid | Northern hemisphere. | Supersedes NSIDC EASE-Grid North, CRS code 3408. This ellipsoidal development is to be preferred for new data. ``` If you examine the syntax, you will see key differences, such as * ~~GEOGCS~~ BASEGEODCRS * ~~UNIT["degree",0.0174532925199433~~ ANGLEUNIT["degree",0.01745329252] I am concerned that the use of https://epsg.io is causing you problems in this definition. all the best marqh -- You are receiving this because you are subscribed to this thread.
