Struct EqualEarthProjection 

pub struct EqualEarthProjection { /* private fields */ }

Equal Earth

Classification: Pseudo cylindrical

Available forms: Forward and inverse, spherical and ellipsoidal projection

Defined area: Global

Alias: eqearth

Domain: 2D

Input type: Geodetic coordinates

Output type: Projected coordinates

Projection String

+proj=eqearth

Usage

The Equal Earth projection is designed for world maps and retains the relative size of areas. It was inspired by the Robinson projection.

Example:

$ echo 122 47 | proj +proj=eqearth +R=1
1.55    0.89

Parameters

Note: All parameters for this projection are optional.

Optional

• +lon_0 (Central meridian)
• +ellps (Ellipsoid name)
• +R (Radius of the sphere)
• +x_0 (False easting)
• +y_0 (False northing)

Trait Implementations

impl Clone for EqualEarthProjection

fn clone(&self) -> EqualEarthProjection

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl CoordinateStep for EqualEarthProjection

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 EqualEarthProjection

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

Formats the value using the given formatter.

impl PartialEq for EqualEarthProjection

fn eq(&self, other: &EqualEarthProjection) -> 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 EqualEarthProjection

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
