    <p>The documentation is a bit unclear on that point; it should perhaps say that <code>KmlGeometry</code> objects cannot be <em>instantiated</em> directly. There are, in fact, several methods on a <code>KmlGeometry</code> object, <a href="https://developers.google.com/earth/documentation/reference/interface_kml_geometry-members" rel="nofollow">which you can see in the documentation</a> if you click through the "List of all members" link (the most relevant ones are inherited from <code>KmlObject</code>).</p> <p>All the different geometry types inherit from <code>KmlGeometry</code>, but since you know that this geometry is a <code>KmlPoint</code>, you can just treat it as a <code>KmlPoint</code> (in other languages you might have to explicitly cast the variable, but, for better or worse, Javascript is more forgiving). In your case, you could do</p> <pre><code>var point = pm.getGeometry(); point.setAltitude(newAltitudeValue); point.setLatLng(...); </code></pre> <p>etc. You can use all the <a href="https://developers.google.com/earth/documentation/reference/interface_kml_point" rel="nofollow">normal KmlPoint methods</a>.</p> <p>Incidentally, if you <em>don't</em> know the specific type of geometry (for instance, if the geometry is returned as the target on a click event and could be anything), you can always ask it with <code>getType</code> inherited from <code>KmlObject</code> (in this case, <code>pm.getGeometry().getType()</code> would return <code>'KmlPoint'</code>), which you could then act upon. Not a perfect reflection system, but it works.</p> <p><strong>Addendum:</strong> Your example KML contains the line</p> <pre><code>&lt;altitude&gt;clampedToGround&lt;/altitude&gt; </code></pre> <p>which is not valid KML. What you probably mean is</p> <pre><code>&lt;altitudeMode&gt;clampToGround&lt;/altitudeMode&gt; </code></pre> <p>Earth discards the element it doesn't understand (though a validator will show this error), but it doesn't especially matter in this case, since <code>clampToGround</code> is the default altitudeMode anyway. This is the cause of any altitude changes being dropped, as <code>clampToGround</code> "indicates to ignore an altitude specification" (<a href="https://developers.google.com/kml/documentation/kmlreference#point" rel="nofollow">per the docs</a>), so the point will be placed at ground level regardless of its altitude value.</p> <p>To be able to change the altitude, either change the KML you're feeding it, using <code>relativeToGround</code> or <code>absolute</code> as the altitudeMode, or use the API to change it, e.g.</p> <pre><code>pm.getGeometry().setAltitudeMode(ge.ALTITUDE_RELATIVE_TO_GROUND); </code></pre> <p>Then any altitude you set via <code>pm.getGeometry().setAltitude(...)</code> should work.</p>

    1. COI will try it and say you something, if it works that would be perfect.

    2. COIt's a good try... something similar of what I tried at first but it's not working. It's true that it returns that it's a KmlPoint, but when you try to set a new Altitude it gives you an error, like you can't access the properties. Thanks for the try, if you find something new let me know.

    3. COI updated my answer to catch the altitudeMode issue in your original code. I should have tested my answer more carefully!

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
