Prime meridian

The WKT for prime meridian is defined in 8.2.2. In this document the following definition from both ISO 19125-1:2004 and OGC 01-009 has been deprecated but is included here for the purposes of documenting backward compatibility:

• <irm longitude> is the longitude of the prime meridian measured from the international reference meridian, positive eastward.
• <angle unit> is an optional attribute, optional for reasons of backward compatibility, but best practice is that it is included in WKT strings. If it is omitted then the value for <irm longitude> shall be given in the CRS’s <cs unit> where this is angular, else in decimal degrees. If the subtype of the geodetic CRS to which the prime meridian is an attribute is geographic, the prime meridian’s <irm longitude> value shall be given in the same angular units as those for the horizontal axes of the geographic CRS; if the geodetic CRS subtype is geocentric the prime meridian’s <irm longitude> value shall be given in degrees. Its <conversion factor> shall be to radians and is the number of radians per unit. <angle unit> is described in 7.4.

Examples of WKT describing a prime meridian:

• PRIMEM["Paris",2.5969213,ANGLEUNIT["grad",0.015707963267949]]
• PRIMEM["Greenwich",0.0]

Fields

type: Option<String>

Indicates the type of prime meridian. Always “PrimeMeridian” for this interface.

name: String

The name of the prime meridian.

longitude: ValueInDegreeOrValueAndUnit

The longitude of the prime meridian. Represented as a number or a value with a unit.

id: Option<Id>

An identifier for the datum ensemble.

ids: Ids

An array of identifiers for the datum ensemble.

Implementations

impl PrimeMeridian

pub fn to_projection_transform(&self, proj_transform: &mut ProjectionTransform)

Convert a PrimeMeridian to a ProjectionTransform

Trait Implementations

impl Clone for PrimeMeridian

fn clone(&self) -> PrimeMeridian

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for PrimeMeridian

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for PrimeMeridian

fn default() -> PrimeMeridian

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for PrimeMeridian

where PrimeMeridian: Default,

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for PrimeMeridian

fn eq(&self, other: &PrimeMeridian) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
