Thanks Andrew for the quick response.....i was busy setting up for the reply. Unfortunately I can’t provide you the link of my website, since it’s under construction at the moment. What I can help you with algorithm and images describing my case:
Image : http://google-maps-api.googlegroups.com/web/GarbagePolylineAppearonDifferentAreaSelected.JPG?gda=jZwxSmIAAAD2QBbUKXEWvOZ2DJrBJujSREvSvfM-wBm2E4H4LleMIJxcQ5h5TEuC1AOoQo3CJwzH6uY7I2dQStp0wMmRx1cWlCobsPwTe01LI6SUXYKYBlXi7dpriIAjJhAipsb2do-CHqjxxwsG8_oKG53kozMh&gsc=JwEQJQsAAACJTJwaHlP-a0_1HOvRfJnv In image Gpolyline1 the blue rectangle is drawn when you click on Select from the context menu and the polylines in the blue rectangle are the active ones. The polylines on left and out of the blue rectangle are the ones which are trash. These lines are like garbage images which keeping moving across the map but are not gone. Image : Image shows the trace image at next zoom level, shifting its position though clearing off the previously selected polyline in image1 Steps considered while drawing polyline are (javascript code): when you "select area" from context menu 3.> function SelectArea() { map.clearOverlays(); ....... .......... ............ DrawRectangle() // the blue selected area .... ....... // AJax call to DB to fetch var polylineString = GetCommaSeperatedPolylineCoordinates (selectedrectangleboundaries); foreach(polylinedata in polylinestring) { var polylineCoords = Parse(polylinedata); // gets the polyline coordinates from lylinedata Foreach(coords in polylinecoords) // collect each coordinates into an array { // add to polyline array var polylinePoints = new GLatLng (polylinecoords.start,polylinecoords.end); polyLineArray.push(polylinePoints); } //Create new polyline var polyline = new GPolyline(polyLineArray, "#0000ff", DefaultPolyLineWeight, 1); map.addOverlay(polyline); } } The garbage image comes when I click 2 different areas on map too quick (almost simultaneously) for a map to plot the polylines in previously selected area. As a result the new area gets selected with fresh set of polylines and the old area has garbage images. Hope I m putting my case correctly!
