2021/11/16 - Amazon Location Service - 5 updated api methods
Changes This release adds the support for Relevance, Distance, Time Zone, Language and Interpolated Address for Geocoding and Reverse Geocoding.
{'PositionFiltering': {'AccuracyBased'}}
Creates a tracker resource in your AWS account, which lets you retrieve current and historical location of devices.
See also: AWS API Documentation
Request Syntax
client.create_tracker(
Description='string',
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.
string
A key identifier for an AWS 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.
This field is optional. If not specified, the default value is TimeBased.
string
[REQUIRED]
Specifies the pricing plan for the tracker resource.
For additional details and restrictions on each pricing plan option, see Amazon Location Service pricing.
string
Specifies the data provider for the tracker resource.
Required value for the following pricing plans: MobileAssetTracking ``| ``MobileAssetManagement
For more information about Data Providers, and Pricing plans, see the Amazon Location Service product page.
Valid values: Esri | Here
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.

{'PositionFiltering': {'AccuracyBased'}}
Updates the specified properties of a given tracker resource.

Description='string',
PositionFiltering='TimeBased'|'DistanceBased'|'AccuracyBased',
PricingPlan='RequestBasedUsage'|'MobileAssetTracking'|'MobileAssetManagement',
PricingPlanDataSource='string',
TrackerName='string'
)
string
Updates the description for the tracker resource.
string
Updates 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 distance are neither evaluated against linked geofence collections, nor stored. This helps control costs by reducing the number of geofence evaluations and device positions to retrieve. Distance-based filtering can also reduce the jitter effect when displaying device trajectory on a map.
string
Updates the pricing plan for the tracker resource.
For more information about each pricing plan option restrictions, see Amazon Location Service pricing.
string
Updates the data provider for the tracker resource.
A required value for the following pricing plans: MobileAssetTracking``| ``MobileAssetManagement
For more information about data providers and pricing plans, see the Amazon Location Service product page
