<i>ol.control.Profil</i> is a control that draw a profil of a 3D lineString
|
|
(with a XYZ or XYZM layout).
|
|
<br/>
|
|
The control can be drawn inside or outside the map.
|
|
<br/>
|
|
It fires an <i>over</i> and <i>out</i> event with informations on the point of the profil
|
|
that is pointed by the mouse (to show the point on the map).
|
|
<ul>
|
|
<li>
|
|
<i>graduation</i> option let you specify the z axis graduation interval
|
|
</li>
|
|
<li>
|
|
<i>zmin</i> option let you specify the z axis origin
|
|
</li>
|
|
<li>
|
|
<i>zmax</i> option let you specify the z axis maximum
|

</li>
|
|
<li>
|
|
<i>amplitude</i> option let you specify the alitude amplitude
|
|
</li>
|
|
<li>
|
|
The <i>popup</i> function lets you show a popup when cursor fly over the profil.
