batch-evaluate-geofences

Description

Evaluates device positions against the geofence geometries from a given geofence collection.

This operation always returns an empty response because geofences are asynchronously evaluated. The evaluation determines if the device has entered or exited a geofenced area, and then publishes one of the following events to Amazon EventBridge:

  • ENTER if Amazon Location determines that the tracked device has entered a geofenced area.
  • EXIT if Amazon Location determines that the tracked device has exited a geofenced area.

Note

The last geofence that a device was observed within is tracked for 30 days after the most recent device position update.

Note

Geofence evaluation uses the given device position. It does not account for the optional Accuracy of a DevicePositionUpdate .

See 'aws help' for descriptions of global parameters.

Synopsis

  batch-evaluate-geofences
--collection-name <value>
--device-position-updates <value>
[--cli-input-json <value>]
[--generate-cli-skeleton <value>]

Options

--collection-name (string)

The geofence collection used in evaluating the position of devices against its geofences.

--device-position-updates (list)

Contains device details for each device to be evaluated against the given geofence collection.

(structure)

Contains the position update details for a device.

Accuracy -> (structure)

The accuracy of the device position.

Horizontal -> (double)

Estimated maximum distance, in meters, between the measured position and the true position of a device, along the Earth's surface.

DeviceId -> (string)

The device associated to the position update.

Position -> (list)

The latest device position defined in WGS 84 format: [X or longitude, Y or latitude] .

(double)

PositionProperties -> (map)

Associates one of more properties with the position update. A property is a key-value pair stored with the position update and added to any geofence event the update may trigger.

Format: "key" : "value"

key -> (string)

value -> (string)

SampleTime -> (timestamp)

The timestamp at which the device's position was determined. Uses ISO 8601 format: YYYY-MM-DDThh:mm:ss.sssZ

Shorthand Syntax:

Accuracy={Horizontal=double},DeviceId=string,Position=double,double,PositionProperties={KeyName1=string,KeyName2=string},SampleTime=timestamp ...

JSON Syntax:

[
  {
    "Accuracy": {
      "Horizontal": double
    },
    "DeviceId": "string",
    "Position": [double, ...],
    "PositionProperties": {"string": "string"
      ...},
    "SampleTime": timestamp
  }
  ...
]

--cli-input-json (string) Performs service operation based on the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, the CLI values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally.

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

See 'aws help' for descriptions of global parameters.

Output

Errors -> (list)

Contains error details for each device that failed to evaluate its position against the given geofence collection.

(structure)

Contains error details for each device that failed to evaluate its position against the geofences in a given geofence collection.

DeviceId -> (string)

The device associated with the position evaluation error.

Error -> (structure)

Contains details associated to the batch error.

Code -> (string)

The error code associated with the batch request error.

Message -> (string)

A message with the reason for the batch request error.

SampleTime -> (timestamp)

Specifies a timestamp for when the error occurred in ISO 8601 format: YYYY-MM-DDThh:mm:ss.sssZ
