             Summary: Some CoordinateOperation created from EPSG database get wrong name/identifier/remarks
                 Key: SIS-483
                 URL: https://issues.apache.org/jira/browse/SIS-483
             Project: Spatial Information Systems
          Issue Type: Task
          Components: Referencing
    Affects Versions: 1.0
            Reporter: Martin Desruisseaux
            Assignee: Martin Desruisseaux
             Fix For: 1.1


Calls to {{CRS.findOperation(sourceCRS, targetCRS)}} sometime produces a {{CoordinateOperation}} with wrong metadata (name, identifiers, remarks, scope). For example requesting an operation from EPSG::4202 to EPSG::4283 should produce the following operation:

{noformat}
CoordinateOperation["AGD66 to GDA94 (19)",
  SourceCRS[GeodeticCRS["AGD66", (...snip...)],
  TargetCRS[GeodeticCRS["GDA94", (...snip...)],
  Method["Coordinate Frame rotation (geog2D domain)"], (...snip...)],
  OperationAccuracy[0.5],
  Scope["Recommended for mid-accuracy use in A.C.T. 1m accuracy."],
  Area["Australia - Australian Capital Territory."],
  BBox[-35.93, 148.76, -35.12, 149.40],
  Id["EPSG", 5827, "9.7", URI["urn:ogc:def:coordinateOperation:EPSG:9.7:5827"]],
  Remark["Replaces nationally-derived transformation code 1458."]]
{noformat}

But we get instead the name _"Ellipsoidal 2D CS. Axes: longitude, latitude. Orientations: east, north. UoM: degree"_ together with identifier and remarks of EPSG::6424 coordinate system. The accuracy, scope, area and bounding box are lost. The bug is in {{EPSGDataAccess}} where metadata are accidentally overwritten before we finished to construct the {{CoordinateOperation}}. This bug affects only metadata; the coordinate operation parameters are unaffected so the numerical results of coordinate operations should be the same.
