Bug NIM100236


The IGeographicCoordinateSystemEdit.Define method fails on defined spatial references, and is making the geographic system object with empty properties.

Additional Information

Projecting a point from one GCS to another normalizes coordinates to +-180 range (left longitude + 360)

Alternate Solution

Use the Define method on a new geographic coordinate system object. This does not make the properties blank. Sample Code: Public Sub CustomGCS() 'create a new spatial regernce factory Dim pSRF As ISpatialReferenceFactory2 Set pSRF = New SpatialReferenceEnvironment 'create a new WGS 1984 coordinate system for providing inputs Dim pInPutGC As IGeographicCoordinateSystem2 Set pInPutGC = pSRF.CreateGeographicCoordinateSystem(esriSRGeoCS_WGS1984) 'create a new geographic coridnate system Dim pOutputGC As IGeographicCoordinateSystem2 Dim pGCS As IGeographicCoordinateSystemEdit Set pOutputGC = New GeographicCoordinateSystem 'set the new coordinate system to IGeographicCoordinateSystemEdit to define custom projections Set pGCS = pOutputGC 'Define custom projection by providing inputs pGCS.Define pInPutGC.Name, pInPutGC.Alias, pInPutGC.Abbreviation, pInPutGC.Remarks, pInPutGC.Usage, pSRF.CreateDatum(esriSRDatumType.esriSRDatum_Abidjan1987), pInPutGC.PrimeMeridian, pInPutGC.CoordinateUnit Debug.Print "START" Debug.Print pOutputGC.Name Debug.Print pOutputGC.Abbreviation Debug.Print pOutputGC.Alias Debug.Print pOutputGC.CoordinateUnit.FactoryCode Debug.Print pOutputGC.Datum.FactoryCode Debug.Print pOutputGC.FactoryCode Debug.Print pOutputGC.LeftLongitude(True) Debug.Print pOutputGC.PrimeMeridian.FactoryCode Debug.Print pOutputGC.RightLongitude(True) Debug.Print "END" End Sub
