 # Tutorial: Implement IoT spatial analytics using Azure Maps
 
-Tracking and capturing relevant events that occur in space and time is a common IoT scenario. For example, in fleet management, asset tracking, mobility, and smart city applications. This tutorial guides you through a solution pattern for using Azure Maps APIs. Relevant events are captured by IoT Hub, using the event subscription model provided by Event Grid.

 This solution demonstrates a scenario where a car rental company plans to monitor and log events for its rental cars. Often car rental companies rent out cars for a specific geographic region and need to keep track of their whereabouts while rented. Instances of a car leaving the chosen geographic region need to be logged. Logging data ensures policies, fees, and other business aspects would be handled properly.
 
-In our use case, the rental cars are equipped with IoT devices that send telemetry data to Azure IoT Hub on a regular basis. The telemetry includes the current location and indicates whether the car's engine is running or not. The device location schema adheres to the IoT [Plug and Play schema for geospatial data](https://github.com/Azure/IoTPlugandPlay/blob/master/Schemas/geospatial.md).
