TryFromAuthorityAndCode(System.String crsAuthority, System.String crsAuthorityCode, out Crs crs)
Returns a Coordinate Reference System specified by authority and code. The datum shift choice is Conservative.Syntax
public static System.Boolean TryFromAuthorityAndCode (
System.String crsAuthority,
System.String crsAuthorityCode,
out Crs crs
)Parameters
crsAuthority
Type: System.String
The name of an authority, often "epsg".
The name of an authority, often "epsg".
crsAuthorityCode
Type: System.String
A unique code for the new instance, according to the authority, for example "3034".
A unique code for the new instance, according to the authority, for example "3034".
crs
Type: Crs
The resulting Coordinate Reference System. This is an output parameter, and it will only be valid if the return value is True.
The resulting Coordinate Reference System. This is an output parameter, and it will only be valid if the return value is True.
Return Value
Type: System.Boolean
In C# and C++ this method returns True if the combination of authority and code matched a Coordinate Reference System that can be created, and False otherwise. In Java and Python, the actual Coordinate Reference System is returned, or null (Java) or None (Python) if no matching Coordinate Reference System was found.

In Java and Python, the actual Coordinate Reference System is returned, or null (Java) or None (Python) if no matching Coordinate Reference System was found.
Remarks
The supported authorities are "EPSG", "ESRI", "IGNF", "CRS" and "OGC". Carmenta methods will regard authority strings as case insensitive.
