[jira] [Commented] (SIS-378) Too aggressive simplification of some
units of measurement
[ https://issues.apache.org/jira/browse/SIS-378?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17416599#comment-17416599 ]
Martin Desruisseaux commented on SIS-378:
-----------------------------------------
Some issues were fixed in SIS 1.0, but we keep this issue open because there is remaining too aggressive simplifications.

> In the left column, some units used by the World Meteorological Organisation (WMO). In the right column, the result of parsing with Apache SIS. Some simplifications are too aggressive, in particular with dimensionless units like radians.
