Too aggressive simplification of some units of measurement



    • Type: Bug
    • Status: Open
    • Priority: Major
    • Resolution: Unresolved
    • Affects Version/s: 0.8
    • Fix Version/s: 1.0, 1.1
    • Component/s: Utilities
    • Labels:


      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.
