## Citation

The terms of use ask to name the Atlas of Switzerland and the data owners, and to keep the source references in exports, screenshots and embeds. Cite the map as:

## Variants

The map has 2 variants. Levels: spatial unit → time. The `u` value of a variant selects it in the links below.

- Cantons
  - 2012: `u=ARMAAwAA` (default)
- Communes
  - 2012: `u=ARMABQAA`

## Links

Replace `{u}` with the `u` value of a variant above, or leave out `u={u}` for the default variant. The map opens at its full extent; a link cannot set the map position.

- Map: https://atlasderschweiz.ch/en/theme/popular-initiative-stop-the-endless-constructionof-second-homes-2012/?u={u}
- Short link, stays valid when the title changes: https://atlasderschweiz.ch/en/t/711/?u={u}
- Side by side with another map: https://atlasderschweiz.ch/en/comparison/?lt=711&lu={u}&rt={id of the other map}&ru={u of the other map, or leave out}

Embed in another website (allowed by the terms of use, as long as the source references stay visible):

```html
<iframe src="https://atlasderschweiz.ch/en/embed/?id=711&u={u}&dm=e&ig=1" style="border:0;width:100%;height:600px;max-width:100%;" loading="lazy" title="Thematic map 'Second Home Initiative (2012)' in the Atlas of Switzerland" allowfullscreen sandbox="allow-scripts allow-same-origin allow-popups" allow="geolocation" referrerpolicy="strict-origin-when-cross-origin"></iframe>
```

In the embed URL, `dm` sets what is shown: `e` the map with its title bar (default), `p` also the values of an object clicked on the map, `m` only the map with a button that opens it in the atlas. `ig=1` (default) lets the map react to scrolling and dragging only after a click into it, `ig=0` right away. The size can be changed in `style`.
