geo.destination

geo.destination(
   $p as cts.point,
   $bearing as Number,
   $distance as Number,
   [$options as String[]]
) as cts.point

Summary

Returns the point at the given distance (in units) along the given bearing (in radians) from the starting point.

Parameters
$p The starting point.
$bearing The bearing, in radians.
$distance The distance, in units. See the units option, below.
$options Options for the operation. The default is ().

Options include:

"coordinate-system=string"
Use the given coordinate system. Valid values are:
wgs84
The WGS84 coordinate system.
wgs84/double
The WGS84 coordinate system at double precision.
etrs89
The ETRS89 coordinate system.
etrs89/double
The ETRS89 coordinate system at double precision.
raw
The raw (unmapped) coordinate system.
raw/double
The raw coordinate system at double precision.
"precision=value"
Use the coordinate system at the given precision. Allowed values: float and double.
"units=value"
Measure distance and the radii of circles in the specified units. Allowed values: miles (default), km, feet, meters.

Usage Notes

The value of the precision option takes precedence over that implied by the governing coordinate system name, including the value of the coordinate-system option. For example, if the governing coordinate system is "wgs84/double" and the precision option is "float", then the operation uses single precision.

Example

var sf = cts.point(37, -122);
var ny = cts.point(40, -73);
geo.destination(sf, 1.22100904274442,
    geo.distance(sf, ny));

=> cts:point("40.009335,-72.997467")
