<h1>MapViewport</h1>
|
|
|
|
|
<p>
|
|
|
|
|
The MapViewport works under the hood of a map layer to track the informations about the current focus point and
|
|
|
|
|
zoom position.
|
|
|
|
|
This is important to maintain the same view when maps are changed.

<p><strong>WHAT TO SEE:</strong> The map should focus Paris.</p>
