2023/10/03 - Amazon Location Service - 5 updated api methods
Changes Amazon Location Service adds support for bounding polygon queries. Additionally, the GeofenceCount field has been added to the DescribeGeofenceCollection API response.
{'KmsKeyEnableGeospatialQueries': 'boolean'}
Creates a tracker resource in your Amazon Web Services account, which lets you retrieve current and historical location of devices.

Request Syntax
client.create_tracker(
Description='string',
EventBridgeEnabled=True|False,
KmsKeyEnableGeospatialQueries=True|False,
KmsKeyId='string',
PositionFiltering='TimeBased'|'DistanceBased'|'AccuracyBased',
PricingPlan='RequestBasedUsage'|'MobileAssetTracking'|'MobileAssetManagement',
PricingPlanDataSource='string',
Tags={
'string': 'string'
},
TrackerName='string'
)
string
An optional description for the tracker resource.
boolean
Whether to enable position UPDATE events from this tracker to be sent to EventBridge.
Note
You do not need enable this feature to get ENTER and EXIT events for geofences with this tracker. Those events are always sent to EventBridge.
boolean
Enables GeospatialQueries for a tracker that uses a Amazon Web Services KMS customer managed key .
This parameter is only used if you are using a KMS customer managed key.
Note
If you wish to encrypt your data using your own KMS customer managed key, then the Bounding Polygon Queries feature will be disabled by default. This is because by using this feature, a representation of your device positions will not be encrypted using the your KMS managed key. The exact device position, however; is still encrypted using your managed key.
You can choose to opt-in to the Bounding Polygon Quseries feature. This is done by setting the KmsKeyEnableGeospatialQueries parameter to true when creating or updating a Tracker.
string
A key identifier for an Amazon Web Services KMS customer managed key . Enter a key ID, key ARN, alias name, or alias ARN.
string
Specifies the position filtering for the tracker resource.
Valid values:
TimeBased - Location updates are evaluated against linked geofence collections, but not every location update is stored. If your update frequency is more often than 30 seconds, only one update per 30 seconds is stored for each unique device ID.
DistanceBased - If the device has moved less than 30 m (98.4 ft), location updates are ignored. Location updates within this area are neither evaluated against linked geofence collections, nor stored. This helps control costs by reducing the number of geofence evaluations and historical device positions to paginate through. Distance-based filtering can also reduce the effects of GPS noise when displaying device trajectories on a map.
AccuracyBased - If the device has moved less than the measured accuracy, location updates are ignored. For example, if two consecutive updates from a device have a horizontal accuracy of 5 m and 10 m, the second update is ignored if the device has moved less than 15 m. Ignored location updates are neither evaluated against linked geofence collections, nor stored. This can reduce the effects of GPS noise when displaying device trajectories on a map, and can help control your costs by reducing the number of geofence evaluations.
This field is optional. If not specified, the default value is TimeBased .
string
No longer used. If included, the only allowed value is RequestBasedUsage .
string
This parameter is no longer used.
dict
Applies one or more tags to the tracker resource. A tag is a key-value pair helps manage, identify, search, and filter your resources by labelling them.
Format: "key" : "value"
Restrictions:
Maximum 50 tags per resource
Each resource tag must be unique with a maximum of one value.
Maximum key length: 128 Unicode characters in UTF-8
Maximum value length: 256 Unicode characters in UTF-8
Can use alphanumeric characters (A–Z, a–z, 0–9), and the following characters: + - = . _ : / @.
Cannot use "aws:" as a prefix for a key.
