preRotateForward()

protected preRotateForward(vec, out): Float64Array

Defined in: src/sdk/geo/GeoProjection.ts:302

Applies a forward rotation to a set of lat/lon coordinates using this projection's pre-projection rotation angles.

Parameters

Parameter	Type	Description
vec	ReadonlyFloat64Array	The lat/lon coordinates to rotate, as [lon, lat] in degrees.
out	Float64Array	The vector to which to write the result.

Returns

Float64Array

The rotated lat/lon coordinates, as [lon, lat] in degrees. The longitude value is guaranteed to be in the range [-180, 180), and the latitude value is guaranteed to be in the range [-90, 90].
