Amazon Location Service Is Now Generally Available with New Routing and Satellite Imagery Capabilities

In December of 2020, we made Amazon Location Service available in preview form for you to start building web and mobile applications with location-based features. Today I’m pleased to announce that we are making Amazon Location generally available along with two new features: routing and satellite imagery.

I have been a full-stack developer for over 15 years. On multiple occasions, I was tasked with creating location-based applications. The biggest challenges I faced when I worked with location providers were integrating the applications into the existing application backend and frontend and keeping the data shared with the location provider secure. When Amazon Location was made available in preview last year, I was so excited. This service makes it possible to build location-based applications with a native integration with AWS services. It uses trusted location providers like Esri and HERE and customers remain in control of their data.

Amazon Location includes the following features:

• Maps to visualize location information.
• Places to enable your application to offer point-of-interest search functionality, convert addresses into geographic coordinates in latitude and longitude (geocoding), and convert a coordinate into a street address (reverse geocoding).
• Routes to use driving distance, directions, and estimated arrival time in your application.
• Trackers to allow you to retrieve the current and historical location of the devices running your tracking-enabled application.
• Geofences to give your application the ability to detect and act when a tracked device enters or exits a geographical boundary you define as a geofence. When a breach of the geofence is detected, Amazon Location will send an event to Amazon EventBridge, which can trigger a downstream set of actions, like invoking an AWS Lambda function or sending a notification using Amazon Simple Notification Service (Amazon SNS). This level of integration with AWS services is one of the most powerful features of Amazon Location. It will help shorten your application’s time to production.

In the preview announcement blog post, Jeff introduced the service functionality in a lot of detail. In this blog post, I want to focus on the new two features: satellite imagery and routing.

Satellite Imagery

You can use satellite imagery to pack your maps with information and provide more context to the map users. It helps the map users answer questions like “Is there a swamp in that area?” or “What does that building look like?”

To get started with satellite imagery maps, go to the Amazon Location console. On Create a new map, choose Esri Imagery. 

Routing
With Amazon Location Routes, your application can request the travel time, distance, and all directions between two locations. This makes it possible for your application users to obtain accurate travel-time estimates based on live road and traffic information.

If you provide these extra attributes when you use the route feature, you can get very tailored information including:

• Waypoints: You can provide a list of ordered intermediate positions to be reached on the route. You can have up to 25 stopover points including the departure and destination.
• Departure time: When you specify the departure time for this route, you will receive a result optimized for the traffic conditions at that time.
• Travel mode: The mode of travel you specify affects the speed and the road compatibility. Not all vehicles can travel on all roads. The available travel modes are car, truck and walking. Depending on which travel mode you select, there are parameters that you can tune. For example, for car and truck, you can specify if you want a route without ferries or tolls. But the most interesting results are when you choose the truck travel mode. You can define the truck dimensions and weight and then get a route that is optimized for these parameters. No more trucks stuck under bridges!

Amazon Location Service and its features can be used for interesting use cases with low effort. For example, delivery companies using Amazon Location can optimize the order of the deliveries, monitor the position of the delivery vehicles, and inform the customers when the vehicle is arriving. Amazon Location can be also used to route medical vehicles to optimize the routing of patients or medical supplies. Logistic companies can use the service to optimize their supply chain by monitoring all the delivery vehicles.

To use the route feature, start by creating a route calculator. In the Amazon Location console, choose Route calculators. For the provider of the route information, choose Esri or HERE.

You can use the route calculator from the AWS SDKs, AWS Command Line Interface (AWS CLI) or the Amazon Location HTTP API.

For example, to calculate a simple route between departure and destination positions using the CLI, you can write something like this:

aws location \
    calculate-route \
        --calculator-name MyExampleCalculator \
        --departure-position -123.1376951951309 49.234371474778385 \
        --destination-position -122.83301379875074 49.235860182576886

The departure-position and destination-positions are defined as longitude, latitude.

This calculation returns a lot of information. Because you didn’t define the travel mode, the service assumes that you are using a car. You can see the total distance of the route (in this case, 29 kilometers). You can change the distance unit when you do the calculation. The service also returns the duration of the trip (in this case, 29 minutes). Because you didn’t define when to depart, Amazon Location will assume that you want to travel when there is the least amount of traffic.

{
    "Legs": [{
        "Distance": 26.549,
        "DurationSeconds": 1711,
        "StartPosition":[-123.1377012, 49.2342994],
        "EndPosition": [-122.833014,49.23592],
        "Steps": [{
            "Distance":0.7,
            "DurationSeconds":52,
            "EndPosition":[-123.1281,49.23395],
            "GeometryOffset":0,
            "StartPosition":[-123.137701,49.234299]},
            ...
        ]
    }],
    "Summary": {
        "DataSource": "Esri",
        "Distance": 29.915115551209176,
        "DistanceUnit": "Kilometers",
        "DurationSeconds": 2275.5813682980006,
        "RouteBBox": [
            -123.13769762299995,
            49.23068000000006,
            -122.83301399999999,
            49.258440000000064
        ]
    }
}

It will return an array of steps, which form the directions to get from departure to destination. The steps are represented by a starting position and end position. In this example, there are 11 steps and the travel mode is a car.

The result changes depending on the travel mode you selected. For example, if you do the calculation for the same departure and destination positions but choose a travel mode of walking, you will get a series of steps that draw the map as shown below. The travel time and distance are different: 24.1 kilometers and 6 hours and 43 minutes.
