Function TransverseMercator.tryReverse

Reverse a projected coordinate.

bool tryReverse(
  const ProjectedCoordinate!T source,
  out GeographicCoordinate!T result
) const pure nothrow @nogc @safe;

The represented-coordinate sheet must correspond to the supported forward domain. Reverse handling preserves the projection's defined pole canonicalization and representation-aware sheet boundaries.

Parameters

NameDescription
source Projected easting and northing in the ellipsoid linear unit.
result Receives the geographic coordinate on success.

Returns

true for a valid projection and supported represented coordinate; otherwise false. On failure result is initialized to .init on entry and has no guaranteed value on failure.

Example

Example reversing a projected coordinate without throwing. 

import geodesy;
const projection = TransverseMercator!double.fromParameters(
    wgs84!double(),
    Latitude!double.fromDegrees(0.0),
    Longitude!double.fromDegrees(15.0),
    0.9996,
    500_000.0,
    0.0);
const source = GeographicCoordinate!double.fromComponents(
    Latitude!double.fromDegrees(48.20849),
    Longitude!double.fromDegrees(16.37208));
GeographicCoordinate!double recovered;
assert(projection.tryReverse(projection.forward(source), recovered));
assert(recovered.latitude.degrees > 48.0);
