Subject [jira] [Created] (SIS-488) Handle wrap-around longitude in NADCON grid
Date Wed, 19 Feb 2020 09:39:00 GMT
Martin Desruisseaux created SIS-488:
---------------------------------------

             Summary: Handle wrap-around longitude in NADCON grid
                 Key: SIS-488
                 URL: https://issues.apache.org/jira/browse/SIS-488
             Project: Spatial Information Systems
          Issue Type: Task
          Components: Referencing
    Affects Versions: 1.0, 0.8, 0.7
            Reporter: Martin Desruisseaux
            Assignee: Martin Desruisseaux


The NADCON grid for Alaska ({{"alaska.las"}} and {{"alaska.los"}} files) have a domain of
validity ranging from -194° to -127.875° of longitude and 46° to 77.125° of latitude.
So it has a part defined beyond the -180° limit, with longitude values between -194° and
-180°. When asking a coordinate transformation at longitude 170°, the {{InterpolatedTransform}}
class should understand that this 170° longitude is actually located at -190° longitude
in the coordinate system of its NADCON grid.
