# GeoArea

Let the user select a polygon.

**Reference type:** {class}`dasf_exb.input_models.GeoArea`

:::{dropdown} Usage

```python
from dasf_exb.input_models import GeoArea


def get_area_info(
    area: GeoArea,
) -> str:
    return ("The following area has been selected:\n" "Points:\n") + "\n".join(
        f"lon: {p.lon}\nlat: {p.lat}" for p in area.points
    )
```

:::

The GeoArea is essentially the same as a list of {ref}`ui-input-geolocation`
(i.e. `List[GeoLocation]`), just that it let's the user select multiple points
which will then be visualized on the map.
