Crs.FromWellKnownText Methods
Returns a new Coordinate Reference System from a definition in Well-Known Text (WKT), throwing an exception on failure.
Thread safety: This method is thread-safe.
Overload List
| Name | Description | |
|---|---|---|
 Public method | FromWellKnownText(System.String wellKnownText) | Returns a new Crs from Well-Known Text (WKT). The DatumShiftChoice will be Conservative if there is no explicit datum shift in the WKT. |
| Public method | FromWellKnownText(System.String wellKnownText, WellKnownTextFlavor flavor, DatumShiftChoice datumShiftChoice) | Returns a new Crs from Well-Known Text (WKT) expressed in a given WKT flavor, using a given DatumShiftChoice. |
| Public method | FromWellKnownText(System.String wellKnownText, DatumShiftChoice datumShiftChoice) | Returns a new Crs from Well-Known Text (WKT), using a given DatumShiftChoice. |
FromWellKnownText(System.String wellKnownText)
Returns a new Crs from Well-Known Text (WKT). The DatumShiftChoice will be Conservative if there is no explicit datum shift in the WKT.Syntax
public static Crs FromWellKnownText (
System.String wellKnownText
)Parameters
wellKnownText
Type: System.String
The Crs definition in WKT.
The Crs definition in WKT.
Return Value
Type: Crs
The Crs defined by the text.
The Crs defined by the text.
Remarks
If the datum shift is not given explicitly in the WKT, a default datum shift for the geodetic datum will be chosen in the Conservative way, so an exception can be thrown if Carmenta does not know any generally useful datum shift. Note that there is an overloaded variant that lets you specify the Lenient datum shift choice instead.
FromWellKnownText(System.String wellKnownText, WellKnownTextFlavor flavor, DatumShiftChoice datumShiftChoice)
Returns a new Crs from Well-Known Text (WKT) expressed in a given WKT flavor, using a given DatumShiftChoice.Syntax
public static Crs FromWellKnownText (
System.String wellKnownText,
WellKnownTextFlavor flavor,
DatumShiftChoice datumShiftChoice
)Parameters
wellKnownText
Type: System.String
The Crs definition in WKT.
The Crs definition in WKT.
flavor
Type: WellKnownTextFlavor
The WKT flavor of the Crs definition.
The WKT flavor of the Crs definition.
datumShiftChoice
Type: DatumShiftChoice
Tells how a default datum shift shall be chosen (Conservative or Lenient) if there is no explicit datum shift in the WKT.
Tells how a default datum shift shall be chosen (Conservative or Lenient) if there is no explicit datum shift in the WKT.
Return Value
Type: Crs
The Crs defined by the text.
The Crs defined by the text.
Remarks
There are many flavors (or dialects) of WKT. This method lets you specify the flavor you intend to read, but that should no longer be necessary, so it is better to use the overloaded variant without a flavor parameter.
FromWellKnownText(System.String wellKnownText, DatumShiftChoice datumShiftChoice)
Returns a new Crs from Well-Known Text (WKT), using a given DatumShiftChoice.Syntax
public static Crs FromWellKnownText (
System.String wellKnownText,
DatumShiftChoice datumShiftChoice
)Parameters
wellKnownText
Type: System.String
The Crs definition in WKT.
The Crs definition in WKT.
datumShiftChoice
Type: DatumShiftChoice
Tells how a default datum shift shall be chosen (Conservative or Lenient) if there is no explicit datum shift in the WKT.
Tells how a default datum shift shall be chosen (Conservative or Lenient) if there is no explicit datum shift in the WKT.
Return Value
Type: Crs
The Crs defined by the text.
The Crs defined by the text.
