The <i>ol.interaction.GeolocationDraw</i> is a draw interaction that use an <i>ol.Geolocation</i>.
|
|
<ul>
|
|
<li>
|
|
<i>setActive(bool)</i> method will start/stop the GPS and draw a location area.
|
|
</li>
|
|
<li>
|
|
<i>start()</i> method will start drawing (registering poisitions).
|
|
</li>
|
|
<li>
|
|
<i>pause()</i> will pause registering locations.
|
|
</li>
|
|
<li>
|
|
<i>stop()</i> method will stop drawing and save the resulting feature in the provided source.
|
|
</li>
|
|
</ul>
|
|
Options:
|
|
<ul>
|
|
<li>
|
|
You can define a <i>minAccuracy</i> overneath the location will be skipped or a <i>condition</i> function
|
|
to decide if the point should be registered.
|
|
</li>
|
|
<li>
|
|
You can define a <i>tolerance</i> to simplify the resulting geometry.
|
|
</li>
|
|
<li>
|
|
When activated the interaction will follow the GPS position at a defined <i>zoom</i>.
|
|
You can override this behavior in specifying the <i>followTrack</i> option (can be true | false | auto | position | visible).
