Questions tagged with Amazon Location Service

I’ve been struggling to create a form that can be filled out to create a tracker at a given location. I have maps set up but haven't been able to create the tracker to be able to pin it; I found the parameters from the AWS SDK but am having trouble implementing it. Here is a snippet of my code: ``` import {AWS} from 'aws-sdk'; export default function Setup() { var location = new AWS.Location({apiVersion: '2020-11-19'}); var params = { TrackerName: 'STRING_VALUE', /* required */ Description: 'STRING_VALUE', KmsKeyId: 'STRING_VALUE', PricingPlanDataSource: 'STRING_VALUE', Tags: { '<TagKey>': 'STRING_VALUE', /* '<TagKey>': ... */ } }; location.createTracker(params, function(err, data) { if (err) console.log(err, err.stack); // an error occurred else console.log(data); // successful response }); return( <form> <div class="form-group"> <label for="truckName">Tracker Name</label> <input type="text" class="form-control" id="truckName" placeholder="Enter Truck Name" /> <small id="trackerHelp" class="form-text text-muted">Please enter the name of your tracker.</small> </div> <button type="submit" class="btn btn-primary" onclick="Setup">Submit</button> </form> ); } ```

Using Amazon Location Services, is there a way to retrieve the alternative routes of getting from origin to destination. It appears that the best possible route is selected when calling the `calculate route/calculate route matrix` api's. However the routes chosen by the API are not preferable to the alternative routes you could find on a map directions application (e.g. google).

I'm attempting to evaluate Amazon Location Service as a replacement for MapBox. The available map styles are here: https://forums.aws.amazon.com/forum.jspa?forumID=394&start=0 This page mentions "Esri map styles that are not listed in this section are currently not supported." **Is there a way to overlay streets on the "Esri Imagery" (aka Satellite Imagery) map?** **Notes:** * I've been using this maplibre-gl-js-react AWS sample as a guide: https://github.com/aws-samples/amazon-location-samples/tree/main/maplibre-gl-js-react * Instructions for creating custom styles are here: https://github.com/aws-samples/amazon-location-samples/tree/main/create-custom-map-style * Unfortunately I'm not able to get that code to work and I seem to be at a dead end there. * However, it is not clear to me whether I would be able to pull a streets layer onto the "Esri Imagery"

Part of our application needs to track the current location of a device every day at midnight with AWS Location. The tracking needs to be based off the devices local timezone. My first though was to have the backend get the devices position daily. But if we used this approach, we would need to do this EVERYTIME its midnight somewhere in the world. This could get expensive quick and does not seem a great approach, both from a user and system efficiency perspective. The other option I though of was having the devices attached to a tracker, but again it does not seem like I configure this to only track location at midnight. So again creates significant additional noise. Does any one have any suggestions or additional methods of doing this? Thanks! Greatly appreciated!

Hi, I am trying to change the location of the mobile device in the AWS device farm by providing correct latitude and longitude but it's now working. Can you please guide me?

Using Postman to send a request to "/routes/v0/calculators/**{{ROUTE_CALCULATOR}}**/calculate/route-matrix" fails with the message: ``User: {{USER}} is not authorized to perform: geo:CalculateRouteMatrix on resource: arn:aws:geo:{{RESOURCE}}`` In the IAM Policy Editor, there is not an option for CalculateRouteMatrix; only CalculateRoute. Calling the /calculate/route API does work correctly, so it does not appear to be a problem in my URL or signing process. Am I doing something wrong or is this a bug? Thanks

I have a map in AWS Location Service and a React frontend with mapbox-gl. When accessing this resource as an authenticated user everything works fine. The attached policies for the unauthenticated role have the same map permissions and yet unauthenticated access does not work. The role has other permissions too for appsync and these do work in both the unauthenticated and authenticated cases which indicates that the role is being assumed in both cases. The error message when trying to access the map as an unauthenticated user states that the user assumed the correct unauthenticated role but was not permitted to access the map but as far as I can tell they are (same policies as authenticated role which works). Could the problem be that my Cognito resources are in eu-west-2 (London) and the map is in eu-west-1 (Ireland) ? If so, not sure why it works for authenticated access. If this is the issue, any idea when the service will be available in eu-west-2?

Hi, I'm just getting started with Amazon Location Services. I've created my first map, and can access it fine as an unauthenticated user. However, I'm trying to now add geocoding functionality, but it's not clear to me how to make access to the 'places' API be unauthenticated. The documentation explicitly covers granting unauthenticated access to maps, but it is silent on this topic for places. I have tried a simple POST to https://places.geo.eu-west-1.amazonaws.com/places/v0/indexes/<placesname>/search/text, but I get back an HTTP 403 response. Can anyone help?

My asset tracking project requires including an accuracy or radius (in meters) for each of the location entries on a tracker. Does ALS support the inclusion of a radius and drawing it on the map with the asset?
