I'm using google map as layer in openlayer. I'm trying to add an point in the
map as in example http://www.logisticsplus-ks.com/testmap/. I'm successfully
adding the point in the map but when I move the map the point changes the
position. So it does not stay at the coordinates that I give it.
By the way the functions works perfectly with openstreet map, but not with
google maps.
In the following is the code that I'm using:
<script type="text/javascript">
var map;
function init() {
map = new OpenLayers.Map('map');
map.addControl(new OpenLayers.Control.LayerSwitcher());
var gmap = new OpenLayers.Layer.Google(
"Google Streets", // the default
{numZoomLevels: 20}
);
map.addLayers([gmap]);
map.setCenter(new OpenLayers.LonLat(21.159739, 42.656138), 10);
}
var featurecollection = {"type":"Feature",
"id":"OpenLayers.Feature.Vector_173", "properties":{},
"geometry":{"type":"Point", "coordinates":[21.159739, 42.656138]}};
function addGeoJson() {
var geojson_format = new OpenLayers.Format.GeoJSON();
var vector_layer = new OpenLayers.Layer.Vector();
map.addLayer(vector_layer);
//vector_layer.addFeatures(geojson_format.read(featurecollection));
vector_layer.addFeatures(geojson_format.read(featurecollection));
}
</script>
Any help would be appreciable.
Thanks in advance,
Hekuran
