Bug NIM100236

Zusammenfassung

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


Zusätzliche Informationen

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


Alternative Lösung

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 <a href="http://pInPutGC.Name" target="_blank">pInPutGC.Name</a>, pInPutGC.Alias, pInPutGC.Abbreviation, pInPutGC.Remarks, pInPutGC.Usage, pSRF.CreateDatum(esriSRDatumType.esriSRDatum_Abidjan1987), pInPutGC.PrimeMeridian, pInPutGC.CoordinateUnit



Debug.Print "START"

Debug.Print <a href="http://pOutputGC.Name" target="_blank">pOutputGC.Name</a>

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"
