Function TransverseMercator.tryForward

Project a geographic coordinate.

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

Non-polar inputs are accepted only for |delta longitude| <= 60 degrees from the natural-origin meridian. Geographic poles are independent of source longitude. Output uses the ellipsoid linear unit.

Parameters

NameDescription
source Geographic source coordinate.
result Receives projected easting and northing on success.

Returns

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

Example

Example projecting a geographic 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));
ProjectedCoordinate!double projected;
assert(projection.tryForward(source, projected));
assert(projected.easting > 500_000.0);
