# Displaying Locations on a Map with TTN LoRaWAN

> This article explains how to send location data from The Things Network (TTN) to TagoIO so that device locations are displayed on a Map widget, including the required JSON payload format and the steps to add the 'location' variable to a dashboard map.

If you have a custom payload format decoder at TTN (The Things Network), you can send your payload variables directly to TagoIO.

To display locations on a Map, your data needs to be sent inside a "location" field with the format shown below:

```json
{
  "variable": "speed",
  "value": 10,
  "location": {
    "lat": 42.2974279,
    "lng": -85.628292
  }
}
```

TagoIO converts latitude and longitude fields to the specific format required, so you don't need to perform any conversions. To accomplish this, you only need to have the variables named `latitude` and `longitude` or `lat` and `lng`. TagoIO will automatically read these variables and create a new variable called `location`.

After your device is sending latitude and longitude information to TagoIO:

- Create a dashboard.
- Add a [Map widget](/docs/tagoio/widgets/map-and-location/map-widget/).
- Look for the device and add the variable `location` inside the Map widget.
