Struct MercatorProjection 

Source 
pub struct MercatorProjection {
    pub earth_radius_m: f64,
}
Expand description

Parameters for a Web-Mercator (EPSG:3857) projection.

Fields§

§earth_radius_m: f64

Earth radius used in the spherical Mercator formula [m].

Implementations§

Source§

impl MercatorProjection

Source

pub fn web_mercator() -> Self

Standard Web Mercator with R = 6 378 137 m.

Source

pub fn forward(&self, pt: LonLat) -> [f64; 2]

Forward projection: geographic (lon, lat) → Mercator (x, y) metres.

Latitude is clamped to ±85.051129° to stay within the Mercator domain.

Source

pub fn inverse(&self, xy: [f64; 2]) -> LonLat

Inverse projection: Mercator (x, y) → geographic (lon, lat).

Source

pub fn forward_all(&self, pts: &[LonLat]) -> Vec<[f64; 2]>

Project an entire LonLat slice to metres.
