Crs.Crs Constructors
Initializes a new instance of the Crs class with the specified Projection and GeodeticDatum, and optionally also Authority and AuthorityCode.
Overload List
| Name | Description | |
|---|---|---|
| Public method | Crs(Projection projection, GeodeticDatum geodeticDatum) | Initializes a new instance of the Crs class with the specified Projection and GeodeticDatum. |
| Public method | Crs(Projection projection, GeodeticDatum geodeticDatum, System.String authority, System.String authorityCode) | Initializes a new instance of the Crs class with the specified Projection, GeodeticDatum, Authority and AuthorityCode. |
Crs(Projection projection, GeodeticDatum geodeticDatum)
Initializes a new instance of the Crs class with the specified Projection and GeodeticDatum.Syntax
public Crs (
Projection projection,
GeodeticDatum geodeticDatum
)Parameters
The map projection.
The geodetic datum.
Remarks
Use this constructor if you need to specify projection and geodeticDatum explicitly, and you do not care that Authority and AuthorityCode will not be set in the Crs.
If you do care, you can use the alternative constructor Crs(projection, geodeticDatum, authority, authorityCode).
Or, if you are lucky you can use the static method FromAuthorityAndCode( authority, authorityCode), which constructs the Crs instance automatically. But that method may throw an exception.
Other ways to construct a Crs are listed under the Crs class documentation.
Crs(Projection projection, GeodeticDatum geodeticDatum, System.String authority, System.String authorityCode)
Initializes a new instance of the Crs class with the specified Projection, GeodeticDatum, Authority and AuthorityCode.Syntax
public Crs (
Projection projection,
GeodeticDatum geodeticDatum,
System.String authority,
System.String authorityCode
)Parameters
The map projection.
The geodetic datum.
The authority, which is often epsg.
The unique code number for Crs instance, according to the authority.
Remarks
If you already know the Authority and AuthorityCode, it is more convenient to use the FromAuthorityAndCode method, which constructs the Crs instance automatically. But that method may throw an exception, so you can use this constructor instead.
Other ways to construct a Crs are listed under the Crs class documentation.
