Google API--KMZ File Not Appearing in Web Map

问题

I am attempting to get a KMZ file to load ontop of a Google Map API and the KMZ file is not appearing. Below is my code and everything executes properly when I load the HTML--the KMZ file is just missing. I tried to minimize the size of the file by converting only one feature layer vs the entire map document to KMZ but I had the same problem.

Ideas?

 <!DOCTYPE html>
<html>
<head>
<title>Map Title, USA</title>
<script src="https://maps.googleapis.com/maps/api/js?key=AIzaSyAx70-         gnDWt1nCCf_pLezTNqZfH2G_im04"></script>
<script>
function initialize() 
{
var mapProp = {
   center:new google.maps.LatLng(38.89,-77),
   zoom:12,
   mapTypeId:google.maps.MapTypeId.SATELLITE
};
    var map = new google.maps.Map(document.getElementById("googleMap"),mapProp);

    var kmlPath = https://sites.google.com/site/geos455assignment/data_files/assignment-4/Turi_Kristen_GEOS455_Assign4.kmz';
    var urlSuffix = (new Date).getTime().toString();

    var layer = new google.maps.KmlLayer(kmlPath + '?' + urlSuffix );
   layer.setMap(map);
 }
google.maps.event.addDomListener(window, 'load', initialize);
</script>`
</head>

<body>
<div id="googleMap" style="width:1384px;height:936px;"></div>

The document is too large:

returns a KmlStatus of "DOCUMENT_TOO_LARGE":

Kml Status:DOCUMENT_TOO_LARGE

Size and Complexity Restrictions for KML Rendering in Google Maps

Google Maps currently has specific limitations to the size and complexity of loaded KML files. Below is a summary of the current limits:

Note: these limits are temporary and are subject to change at any time.

Maximum fetched file size (raw KML, raw GeoRSS, or compressed KMZ) 3MB
Maximum uncompressed KML file size 10MB
Maximum number of Network Links 10
Maximum number of total document-wide features 1,000

Your KML is 18.3 MB, it needs to be less than 10MB.

Your options are:

break your KMZ file into 2 separate files containing KML of < 10 MB
use a third party KMZ parser (like geoxml3), but that may have performance issues. Example using geoxml3 (kmz branch) and your KMZ hosted on my server)
