Can i change the POI location dynamically?

Can i change the POI location dynamically?

Of course you can. After creating the POI (GeoObject) you can change the properties of its GeoLocation.

Here is a quick example how to do this:
// create the POI
var loc = new AR.GeoLocation(47, 12);
var drawable = new AR.Circle(1);
var poi = new AR.GeoObject(loc, {drawables: {cam: drawable}});

// change its location afterwards
loc.latitude = 48;
// or animate it
var anim = new AR.PropertyAnimation(loc, "latitude", null, 48, 2000);
anim.start();

Let us know if you have any question to this.

Thanks for your answer
I finally made it works.

but it makes me wonder why the world scale is so small?
according to the sample project, if i change it to 48 the POI is just gone from the screen. only when i change it to values from 47.772 to 47.774 it works.
how can i change the scale and make it bigger?

The values are representing longitude and latitude from the geographic coordinate system - so they represent the actual value of the geo position. See this Wikipedia article for more information:
