Struct OrthometricHeightM 

pub struct OrthometricHeightM {
    pub value_m: f64,
}

Orthometric height H in metres above the EGM96 mean sea level geoid.

DTED/SRTM terrain postings use this datum. Convert to ellipsoidal height only through Self::to_ellipsoidal_height_deg or Self::to_ellipsoidal_height_rad, which require a pinned geoid tier.

Fields

value_m: f64

Orthometric height H in metres.

Implementations

impl OrthometricHeightM

pub const fn new(value_m: f64) -> Self

Build an orthometric height H in metres.

pub const fn metres(self) -> f64

Return the orthometric height H in metres.

pub fn to_ellipsoidal_height_deg( self, latitude_deg: f64, longitude_deg: f64, geoid: TerrainGeoidModel<'_>, ) -> Result<EllipsoidalHeightM, TerrainDatumError>

Convert this orthometric height to ellipsoidal height h = H + N.

Inputs are geodetic (latitude_deg, longitude_deg), matching the geoid module’s axis order. Terrain lookup APIs use (longitude_deg, latitude_deg), so call sites should pass the axes deliberately.

TerrainGeoidModel::Egm96OneDegree uses the embedded EGM96 1-degree grid. It agrees with the full EGM96 15-arcminute grid to about 0.4 m RMS, so byte-identical terrain heights do not imply byte-identical ellipsoidal heights across geoid tiers.

pub fn to_ellipsoidal_height_rad( self, latitude_rad: f64, longitude_rad: f64, geoid: TerrainGeoidModel<'_>, ) -> Result<EllipsoidalHeightM, TerrainDatumError>

Convert this orthometric height to ellipsoidal height h = H + N.

Inputs are geodetic (latitude_rad, longitude_rad), matching the geoid module’s axis order. TerrainGeoidModel::Egm96OneDegree uses the embedded EGM96 1-degree grid. It agrees with the full EGM96 15-arcminute grid to about 0.4 m RMS, so byte-identical terrain heights do not imply byte-identical ellipsoidal heights across geoid tiers.

Trait Implementations

impl Clone for OrthometricHeightM

fn clone(&self) -> OrthometricHeightM

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for OrthometricHeightM

impl Debug for OrthometricHeightM

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

Formats the value using the given formatter.

impl PartialEq for OrthometricHeightM

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