  11. def fromEpsgCode(epsgCode: Int): CRS

    Creates a CoordinateReferenceSystem (CRS) from an EPSG code.

  12. def fromName(name: String): CRS

    Creates a CoordinateReferenceSystem (CRS) from a well-known name.

    Creates a CoordinateReferenceSystem (CRS) from a well-known name. CRS names are of the form: "authority:code", with the components being:

    • authority is a code for a namespace supported by PROJ.4. Currently supported values are EPSG, ESRI, WORLD, NA83, NAD27. If no authority is provided, the EPSG namespace is assumed.
    • code is the id of a coordinate system in the authority namespace. For example, in the EPSG namespace a code is an integer value which identifies a CRS definition in the EPSG database. (Codes are read and handled as strings).

    An example of a valid CRS name is EPSG:3005.

    name

    the name of a coordinate system, with optional authority prefix

    returns

    the CoordinateReferenceSystem corresponding to the given name

  13. def fromString(name: String, proj4Params: String): CRS

    Creates a CoordinateReferenceSystem from a PROJ.

    Creates a CoordinateReferenceSystem from a PROJ.4 projection parameter string.

    An example of a valid PROJ.4 projection parameter string is:

    +proj=aea +lat_1=50 +lat_2=58.5 +lat_0=45 +lon_0=-126 +x_0=1000000 +y_0=0 +ellps=GRS80 +units=m
    

    name

    a name for this coordinate system.

    proj4Params

    a PROJ.4 projection parameter string

    returns

    the specified CoordinateReferenceSystem

  14. def fromString(proj4Params: String): CRS

    Creates a CoordinateReferenceSystem from a PROJ.

    Creates a CoordinateReferenceSystem from a PROJ.4 projection parameter string.

    An example of a valid PROJ.4 projection parameter string is:

    +proj=aea +lat_1=50 +lat_2=58.5 +lat_0=45 +lon_0=-126 +x_0=1000000 +y_0=0 +ellps=GRS80 +units=m
    

    proj4Params

    a PROJ.4 projection parameter string

    returns

    the specified CoordinateReferenceSystem

  15. def fromWKT(wktString: String): CRS

    Creates a CoordinateReferenceSystem (CRS) from a well-known-text String.
