Struct LambertEqualAreaConicProjection 

pub struct LambertEqualAreaConicProjection { /* private fields */ }

Lambert Equal Area Conic Projection

Classification: Conical

Available forms: Forward and inverse, spherical and ellipsoidal

Defined area: Global

Alias: leac

Domain: 2D

Input type: Geodetic coordinates

Output type: Projected coordinates

Projection String

+proj=leac

Parameters

Note: All parameters are optional for the Lambert Equal Area Conic projection.

Required Parameters

• lat1: Latitude of the first standard parallel.
• +south: Sets the second standard parallel to 90°S. When the flag is off, the second standard parallel is set to 90°N.

Optional Parameters

• lon0: Longitude of the central meridian.
• ellps: Name of the reference ellipsoid.
• R: Radius of the sphere if ellps is not specified.
• x0: False easting (coordinate offset in the x-direction).
• y0: False northing (coordinate offset in the y-direction).

Trait Implementations

impl Clone for LambertEqualAreaConicProjection

fn clone(&self) -> LambertEqualAreaConicProjection

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl CoordinateStep for LambertEqualAreaConicProjection

fn new(proj: Rc<RefCell<Proj>>) -> Self

Create a new Converter

fn forward<P: TransformCoordinates>(&self, p: &mut P)

forward conversion

fn inverse<P: TransformCoordinates>(&self, p: &mut P)

inverse conversion

impl Debug for LambertEqualAreaConicProjection

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

Formats the value using the given formatter.

impl PartialEq for LambertEqualAreaConicProjection

fn eq(&self, other: &LambertEqualAreaConicProjection) -> 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.

impl ProjectCoordinates for LambertEqualAreaConicProjection

fn code(&self) -> i64

ESPG code for this projection

fn name(&self) -> &'static str

Projection name

fn names() -> &'static [&'static str]

Returns the list of canonical names for this projection. This is an associated function, similar to a static method.

fn datum_type() -> u8

get the datum type. Defaults to no datum
