Struct GeocentricTranslation

Translation parameters from a source geocentric frame to a target geocentric frame using EPSG method 1031.

struct GeocentricTranslation(T)
  
if (isGeodesyScalar!T);

All three translations use the same linear unit as source and target geocentric coordinates. The represented direction is source to target: target components equal source components plus the corresponding translation. .init is therefore the identity transformation.

inverse returns the exact inverse parameterization by negating all three translations. Construction rejects non-finite parameters.

Properties

NameTypeDescription
deltaX[get] TX-axis translation in the coordinate linear unit.
deltaY[get] TY-axis translation in the coordinate linear unit.
deltaZ[get] TZ-axis translation in the coordinate linear unit.

Methods

NameDescription
fromComponents (deltaX, deltaY, deltaZ) Construct source-to-target translation parameters.
inverse () Return the exact inverse parameterization.
tryFromComponents (deltaX, deltaY, deltaZ, result) Construct source-to-target translation parameters without throwing.

Example

Example using struct GeocentricTranslation(T) if (isGeodesyScalar!T). 

import geodesy;

const shift = GeocentricTranslation!double.fromComponents(
    84.87, 96.49, 116.95);

const source = GeocentricCoordinate!double.fromComponents(
    3_771_793.97, 140_253.34, 5_124_304.35);

const target = source.applyGeocentricTranslation(shift);
const recovered = target.applyGeocentricTranslation(shift.inverse);

assert(target.x > source.x);
assert(recovered == source);
