Response Structure

  • (dict) –

    • Entries (list) –

      Contains a list of geofences stored in the geofence collection.

      • (dict) –

        Contains a list of geofences stored in a given geofence collection.

        Note

        The returned geometry will always match the geometry format used when the geofence was created.

        • GeofenceId (string) –

          The geofence identifier.

        • Geometry (dict) –

          Contains the geofence geometry details describing a polygon or a circle.

          • Polygon (list) –

            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.

            • (list) –

              • (list) –

                • (float) –

          • Circle (dict) –

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

            • Center (list) –

              A single point geometry, specifying the center of the circle, using WGS 84 coordinates, in the form [longitude, latitude].

              • (float) –

            • Radius (float) –

              The radius of the circle in meters. Must be greater than zero and no larger than 100,000 (100 kilometers).

          • Geobuf (bytes) –

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

            A polygon in Geobuf format can have up to 100,000 vertices.

        • Status (string) –

          Identifies the state of the geofence. A geofence will hold one of the following states:

          • ACTIVE — The geofence has been indexed by the system.

          • PENDING — The geofence is being processed by the system.

          • FAILED — The geofence failed to be indexed by the system.

          • DELETED — The geofence has been deleted from the system index.

          • DELETING — The geofence is being deleted from the system index.

        • CreateTime (datetime) –

          The timestamp for when the geofence was stored in a geofence collection in ISO 8601 format: YYYY-MM-DDThh:mm:ss.sssZ

        • UpdateTime (datetime) –

          The timestamp for when the geofence was last updated in ISO 8601 format: YYYY-MM-DDThh:mm:ss.sssZ

        • GeofenceProperties (dict) –

          User defined properties of the geofence. A property is a key-value pair stored with the geofence and added to any geofence event triggered with that geofence.

          Format: "key" : "value"

          • (string) –

            • (string) –

    • NextToken (string) –

      A pagination token indicating there are additional pages available. You can use the token in a following request to fetch the next set of results.
