GeofenceGeometry

Contains the geofence geometry details.

A geofence geometry can be a circle, a polygon, or a multipolygon. Polygon and MultiPolygon geometries can be defined using their respective parameters, or encoded in Geobuf format using the Geobuf parameter. Including multiple geometry types in the same request will return a validation error.

Note

Amazon Location doesn't currently support polygons that cross the antimeridian.

Circle

A circle on the earth, as defined by a center point and a radius.

Type: Circle object

Required: No

Geobuf

Geobuf is a compact binary encoding for geographic data that provides lossless compression of GeoJSON polygons. The Geobuf must be Base64-encoded.

This parameter can contain a Geobuf-encoded GeoJSON geometry object of type Polygon OR MultiPolygon. For more information and specific configuration requirements for these object types, see Polygon and MultiPolygon.

Note

The following limitations apply specifically to geometries defined using the Geobuf parameter, and supercede the corresponding limitations of the Polygon and MultiPolygon parameters:

A Polygon in Geobuf format can have up to 25,000 rings and up to 100,000 total vertices, including all vertices from all component rings.
A MultiPolygon in Geobuf format can contain up to 10,000 Polygons and up to 100,000 total vertices, including all vertices from all component Polygons.

Type: Base64-encoded binary data object

Length Constraints: Minimum length of 0. Maximum length of 700000.

Required: No

Polygon

A Polygon is a list of up to 250 linear rings which represent the shape of a geofence. This list must include 1 exterior ring (representing the outer perimeter of the geofence), and can optionally include up to 249 interior rings (representing polygonal spaces within the perimeter, which are excluded from the geofence area).

A linear ring is an array of 4 or more vertices, where the first and last vertex are the same (to form a closed boundary). Each vertex is a 2-dimensional point represented as an array of doubles of length 2: [longitude, latitude].

Each linear ring is represented as an array of arrays of doubles ([[longitude, latitude], [longitude, latitude], ...]). The vertices for the exterior ring must be listed in counter-clockwise sequence. Vertices for all interior rings must be listed in clockwise sequence.

The list of linear rings that describe the entire Polygon is represented as an array of arrays of arrays of doubles ([[[longitude, latitude], [longitude, latitude], ...], [[longitude, latitude], [longitude, latitude], ...], ...]). The exterior ring must be listed first, before any interior rings.

Note

The following additional requirements and limitations apply to geometries defined using the Polygon parameter:

The entire Polygon must consist of no more than 1,000 vertices, including all vertices from the exterior ring and all interior rings.
Rings must not touch or cross each other.
All interior rings must be fully contained within the exterior ring.
Interior rings must not contain other interior rings.
No ring is permitted to intersect itself.

Type: Array of arrays of arrays of doubles

Array Members: Minimum number of 1 item. Maximum number of 250 items.

Array Members: Minimum number of 4 items.

Array Members: Fixed number of 2 items.

Required: No
