Documentation

Contains the geofence geometry details.

A geofence geometry is made up of either a polygon or a circle. Can be either a polygon or a circle. Including both will return a validation error.

Amazon Location doesn't currently support polygons with holes, multipolygons, polygons that are wound clockwise, or that cross the antimeridian.

See: newGeofenceGeometry smart constructor.

Create a value of GeofenceGeometry with all optional fields omitted.

Use generic-lens or optics to modify other optional fields.

The following record fields are available, with the corresponding lenses provided for backwards compatibility:

$sel:circle:GeofenceGeometry', geofenceGeometry_circle - A circle on the earth, as defined by a center point and a radius.

$sel:polygon:GeofenceGeometry', geofenceGeometry_polygon - A polygon is a list of linear rings which are each made up of a list of vertices.

Each vertex is a 2-dimensional point of the form: [longitude, latitude]. This is represented as an array of doubles of length 2 (so [double, double]).

An array of 4 or more vertices, where the first and last vertex are the same (to form a closed boundary), is called a linear ring. The linear ring vertices must be listed in counter-clockwise order around the ring’s interior. The linear ring is represented as an array of vertices, or an array of arrays of doubles ([[double, double], ...]).

A geofence consists of a single linear ring. To allow for future expansion, the Polygon parameter takes an array of linear rings, which is represented as an array of arrays of arrays of doubles ([[[double, double], ...], ...]).

A linear ring for use in geofences can consist of between 4 and 1,000 vertices.
