# Code examples and tutorials for working with Amazon Location Service
<a name="samples"></a>

This topic shows a list of code examples, tutorials, and blog posts to help you learn about Amazon Location Service. Each code example includes a description of how it works.

You can find additional samples on the [AWS Geospatial GitHub page](https://github.com/orgs/aws-geospatial/repositories), the [AWS samples GitHub page for Amazon Location](https://github.com/aws-samples/amazon-location-samples), and on the [AWS blog site](https://aws.amazon.com/blogs/mobile/category/mobile-services/amazon-location/).

**Note**  
It is good to understand the difference between the AWS Geospatial GitHub page and the AWS samples GitHub page.  
**Geospatial GitHub** – The [AWS Geospatial GitHub page](https://github.com/orgs/aws-geospatial/repositories) includes samples that are created and maintained by the Amazon Location Service team.
**Samples GitHub** – The [AWS samples GitHub page for Amazon Location](https://github.com/aws-samples/amazon-location-samples) includes samples that were created for Amazon Location, but may or may not be actively maintained.

The [quick start](sample-quick-start.md) tutorial is a good place to start before using other samples, as it shows how to complete prerequisites that are useful for most of the samples.

# Amazon Location Demo site
<a name="sample-demo-site"></a>

![\[alt text not found\]](http://docs.aws.amazon.com/location/previous/developerguide/images/samples/location-demo-site-samples.png)


You can see demos with source code of Amazon Location Service in action at the [Amazon Location Demo site](https://location.aws.com/). This site includes a [hosted web demo](https://location.aws.com/demo), and also a demo app for [Android](https://play.google.com/store/apps/details?id=com.aws.amazonlocation).

You can also find a wide array of samples, filterable by features, language, and platform in the site's [Samples](https://location.aws.com/samples) page.

# Tutorial: Quick start
<a name="sample-quick-start"></a>

![\[alt text not found\]](http://docs.aws.amazon.com/location/previous/developerguide/images/samples/quickstart-both.png)


There are quick start tutorials available for web, iOS, and Android devices. For each platform, the tutorial shows you how to add an interactive map to an application, and how to make calls to the Amazon Location Service APIs from your application. The tutorial is available for JavaScript in a static webpage, Kotlin for an Android phone application, or Swift for an iOS application.

![\[alt text not found\]](http://docs.aws.amazon.com/location/previous/developerguide/images/samples/database-validation_small.png)


This tutorial shows you how to use Amazon Location Service, called from AWS Lambda to normalize addresses and add latitude and longitude to records in an Amazon Aurora database. Uses Amazon Aurora and AWS Lambda.

# Example: Explore app
<a name="example-explore"></a>

![\[alt text not found\]](http://docs.aws.amazon.com/location/previous/developerguide/images/samples/ExploreSample_small.png)


One of the best ways to learn about the functionality of Amazon Location Service is to use the [Explore functionality](https://console.aws.amazon.com/location/explore/home) within the Amazon Location console. This full web application example mimics the maps, places, routes, geofences, and trackers functionality from the console to show you how to recreate these features in your own app. Uses Amplify, React, and JavaScript.

This blog post shows different ways to notify customers with estimated delivery times. It explains using routes to show estimated driving time, and then using trackers and geofences to notify when a driver gets close to the customer. Uses Amplify, React, Amazon EventBridge, and Amazon Simple Notification Service (Amazon SNS).

**Kinesis Stream To Tracker App**: This sample demonstrates how to use Kinesis Data Stream to post tracker updates with Amazon Location Service. The sample is a deployable lambda application written in python that can be integrated with a Kinesis Data Stream to consume the Kinesis events and batch update device positions.

Repository link: [ Amazon Location Amazon Kinesis Data Streams Stream To Tracker App](https://github.com/aws-geospatial/amazon-location-stream-device-data-to-tracker-lambda)

For more information on tracking and geofences, see the [Geofences and Trackers](https://docs.aws.amazon.com/location/previous/developerguide/geofence-tracker-concepts.html) documentation. Developers can deploy the app by following the [AWS's Serverless Application Repository](https://docs.aws.amazon.com/serverlessrepo/latest/devguide/serverlessrepo-how-to-consume.html) documentation, or dicretly from the [Lambda console](https://console.aws.amazon.com/lambda/home#/create/app?applicationId=arn:aws:serverlessrepo:us-east-1:003883091127:applications/kinesis-stream-device-data-to-amazon-location-tracker).

**Device Position Streaming Sample App**: This code example shows how to stream device position data to a Kinesis Data Stream and how geofence notifications work. This app depends on the Kinesis Stream to Tracker Sample App, listed above, to be running for the streamed tracker positions to be updated in Amazon Location Service.
