Struct OrthographicProjection 

pub struct OrthographicProjection { /* private fields */ }

Orthographic

The orthographic projection is a perspective azimuthal projection centered around a given latitude and longitude.

Classification: Azimuthal

Available forms: Forward and inverse, spherical and ellipsoidal

Defined area: Global, although only one hemisphere can be seen at a time

Alias: ortho

Domain: 2D

Input type: Geodetic coordinates

Output type: Projected coordinates

Projection String

+proj=ortho

Required Parameters

• None

Optional Parameters

• +alpha=<value>: Azimuth clockwise from north at the center of projection. Defaults to 0.0. (added in PROJ 9.5.0)
• +k_0=<value>: Scale factor. Determines scale factor used in the projection. Defaults to 1.0. (added in PROJ 9.5.0)
• +lon_0=<value>
• +lat_0=<value>
• +ellps=<value>
• +R=<value>
• +x_0=<value>
• +y_0=<value>

Notes

• Before PROJ 7.2, only the spherical formulation was implemented. To replicate PROJ < 7.2 results with newer versions, force the ellipsoid to a sphere using +f=0.
• This projection method corresponds to EPSG:9840 (or EPSG:1130 with k_0 or alpha).

Trait Implementations

impl Clone for OrthographicProjection

fn clone(&self) -> OrthographicProjection

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl CoordinateStep for OrthographicProjection

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 OrthographicProjection

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

Formats the value using the given formatter.

impl PartialEq for OrthographicProjection

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

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
