geo:destination(
   $p as cts:point,
   $bearing as xs:double,
   $distance as xs:double,
   [$options as xs: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 with degrees as the angular unit. wgs84/radians The WGS84 coordinate system with radians as the angular unit. wgs84/double The WGS84 coordinate system at double precision with degrees as the angular unit. wgs84/radians/double The WGS84 coordinate system at double precision with radians as the angular unit. 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

let $sf := cts:point(37, -122)
let $ny := cts:point(40, -73)
return
geo:destination($sf, 1.22100904274442,
    geo:distance($sf, $ny))

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