Struct Enu

pub struct Enu {
    pub east: Meters,
    pub north: Meters,
    pub up: Meters,
}

Enu is East, North, Up in Meters.

East-North-Up are cartesian coordinates rooted at some reference point’s local tangent plane. That reference location is not included in the Enu struct, so re-contextualizing an Enu to a Lle or Xyz requires knowing the point at which the observation was taken from or was in reference to.

These measures are cartesian in the local tangent plane, which is to say, increasing “North” will continue straight ahead, but not following the curve of the Earth – so you’ll slowly get further and further away from Earth’s surface.

Fields

east: Meters

East is the distance in the easterly direction on some local tangent plane reference. This may be negative to indicate a westerly distance.

north: Meters

North is the distance in the northernly direction on some local tangent plane reference. This may be negative to indicate a southern distance.

up: Meters

Up is the distance above the local tangent plane that intersects with the coordinate system ellipsoid (this is not the same as altitude above the surface, this is elevation above the ellipsoid).

Implementations

impl Enu

pub fn to_lle<CoordinateSystem, LleAngularMeasure>( &self, obs: &Lle<CoordinateSystem, LleAngularMeasure>, ) -> Lle<CoordinateSystem, LleAngularMeasure>

where Radians: From<LleAngularMeasure> + Copy, LleAngularMeasure: From<Radians> + Copy, CoordinateSystem: CoordinateSystem<LleAngularMeasure>,

Take some observation (self), and contextualize it into some absolute Lle given some reference point obs that this Aer is in reference to.

Trait Implementations

impl Clone for Enu

fn clone(&self) -> Enu

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Enu

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

Formats the value using the given formatter.

impl From<Aer<Radians>> for Enu

fn from(aer: Aer<Radians>) -> Self

Convert to Enu cartesian local tangent plane coordinates from an Aer local tangent plane angular measurement in Radians.

impl From<Aer> for Enu

fn from(aer: Aer<Degrees>) -> Self

Convert to Enu cartesian local tangent plane coordinates from an Aer local tangent plane angular measurement in Degrees.

impl From<Enu> for Aer<Degrees>

impl PartialEq for Enu

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