I am trying to display a map, zoom into a zipcode, and then place Congressional District overlay onto map. The overlay is here: https://www.google.com/fusiontables/DataSource?snapid=S506424n-DY
I downloaded the KML link file, and saved it onto my local IIS server. However, the overlay never is drawn.
I also added the following mime types to my IIS Server:
.kml application/vnd.google-earth.kml+xml
.kmz application/vnd.google-earth.kmz
The kml file looks like this:
<?xml version="1.0" encoding="UTF-8"?>
<kml xmlns="http://www.opengis.net/kml/2.2">
<NetworkLink>
<name><![CDATA[2012 US Congressional Districts]]></name>
<Link>
<href>
https://www.google.com/fusiontables/exporttable?query=select+col5+from+1QlQxBF17RR-89NCYeBmw4kFzOT3mLENp60xXAJM&o=kmllink&g=col5</href>
</Link>
My HTML/javascript looks like:
<script src="http://maps.googleapis.com/maps/api/js" type="text/javascript"></script>
<script language="javascript">
var map;
var marker;
function showAddress() {
$("#divGoogleMap").css('display', '');
var mapProp = {
center: new google.maps.LatLng(51.508742, -0.120850),
zoom: 11,
mapTypeId: google.maps.MapTypeId.TERRAIN
};
map = new google.maps.Map(document.getElementById("divGoogleMap"), mapProp);
myListener = google.maps.event.addListener(map, 'click', function (event) {
placeMarker(event.latLng);
});
google.maps.event.addListener(map, 'drag', function (event) {
placeMarker(event.latLng);
});
var zipCode = $("#txtZip").val();
var geocoder = new google.maps.Geocoder();
geocoder.geocode({ 'address': zipCode }, function (results, status) {
if (status == google.maps.GeocoderStatus.OK) {
//Got result, center the map and put it out there
var pos = results[0].geometry.location;
saveLocation(pos);
map.setCenter(pos);
marker = new google.maps.Marker({
map: map,
draggable: true,
position: pos
});
} else {
alert("Geocode was not successful for the following reason: " + status);
}
});
var kmlUrl = '/DesktopModules/HelloWorld/2012_US_Congressional_Districts.kml';
var kmlOptions = {
suppressInfoWindows: true,
preserveViewport: false,
map: map
};
var kmlLayer = new google.maps.KmlLayer(kmlUrl, kmlOptions);
}
function placeMarker(location) {
if (marker) {
marker.setPosition(location);
} else {
marker = new google.maps.Marker({
position: location,
map: map,
draggable: true
});
google.maps.event.addListener(marker, "drag", function (mEvent) {
populateInputs(mEvent.latLng);
});
}
saveLocation(location);
}
function saveLocation(pos) {
$("#hfLatitude").val(pos.lat());
$("#hfLogitude").val(pos.lng());
}
</script>
<table cellpadding="2" cellspacing="2" border="0">
<tr>
<td>
<asp:TextBox ID="txtZip" ClientIDMode="Static" runat="server"></asp:TextBox>
</td>
<td>
<input type="button" id="btnSearch" value="Search" onclick="showAddress()" />
</td>
</tr>
</table>
<div id="divGoogleMap" style="width: 800px;height: 600px;display: none;"></div>
<asp:HiddenField ID="hfLatitude" ClientIDMode="Static" runat="server" />
<asp:HiddenField ID="hfLongitude" ClientIDMode="Static" runat="server" />
What am I doing wrong here?
For use in google maps th kml must be located in an accessible server e not in local.
This is form google doc.
Overview
The Google Maps API supports the KML and GeoRSS data formats for displaying geographic information. These data formats are displayed on a map using a KmlLayer object, whose constructor takes the URL of a publicly accessible KML or GeoRSS file.
the constructor take the URL of a publicly accessible KML.
Then for yoour need you must place your kml in a publicly accessible server
I had forgotten that i had already had a similar experience some years ago and the solution was precisely to place the files kml on a server accessible from the Internet.
