# Reverse geocoding

## Overview

Reverse geocoding using provided longitude and latitude to gain a human-readable street address.

## Example & DSL attributes

```yaml
reverse geocoding:
  name: googleLookup
  apiKey: BJazSyDCKmFA1bTBjAp4beYMp7sVVSAqfBtNeuZ0
  response field: currentLocation
```

### Google Geocode Requests

Joule calls the Google geocode api directly using the provided api key and latitude and longitude provided attributes.

{% hint style="info" %}
Google Geocode request used

[https://maps.googleapis.com/maps/api/geocode/json?latlng=40.714224,-73.961452\&key=YOUR\_API\_KEY](https://maps.googleapis.com/maps/api/geocode/json?latlng=40.714224,-73.961452\&key=YOUR_API_KEY)
{% endhint %}

**Note** Be aware a high frequency of google api calls will incur high charges against your google project. Joule will cache responses based upon matching `latlng` to reduce calls.

### Response

This is a direct Google Geocode API request which places the response payload in the response field. Further details on what is returned can be found [here](https://developers.google.com/maps/documentation/geocoding/start?_gl=1*13qcz28*_up*MQ..*_ga*NzIzNTg3MDg5LjE3MTYyMTQyOTY.*_ga_NRWSTWS78N*MTcxNjIxNDI5Ni4xLjAuMTcxNjIxNDI5Ni4wLjAuMA..#quotas).
