Google Maps API V3: KML Layer not showing?

android google maps kml example
google maps api layers
google maps kml not displaying
display kml file on website
google maps api export kml
read kml file in javascript
multiple kml layers google maps
combine kml files google maps

I have a KML file that I copy/paste together form a fusiontable which looks like this:

<?xml version="1.0" encoding="UTF-8"?>
<kml xmlns="">
<Polygon><outerBoundaryIs><LinearRing><coordinates>-73.992177,40.743465,0.0 -74.008242,40.752352,0.0 -74.006533,40.756112,0.0 -73.983973,40.748934,0.0 -73.987733,40.744149,0.0 -73.992177,40.743465,0.0</coordinates></LinearRing></outerBoundaryIs></Polygon>
<Polygon><outerBoundaryIs><LinearRing><coordinates>-73.973035,40.689458,0.0 -73.989784,40.683305,0.0 -74.008242,40.686381,0.0 -73.978846,40.705181,0.0 -73.977479,40.698003,0.0 -73.973035,40.689458,0.0</coordinates></LinearRing></outerBoundaryIs></Polygon>

As far as I understand drawing these on the map is as easy as

var zipoverlay = new google.maps.KmlLayer('zips.kml');

But apparently this does nothing. Is it not as magical as I thought?


Thanks to Dr.Molle we figured this out. Here's what I did wrong:

  1. The KML file needs to be accessible from outside my own machine. Host it somewhere else in order for maps to be able to grab it
  2. The structure of the KML file needs to be like this:


<?xml version="1.0" encoding="UTF-8"?>
<kml xmlns="">
<Polygon><outerBoundaryIs><LinearRing><coordinates>-73.992177,40.743465,0.0 -74.008242,40.752352,0.0 -74.006533,40.756112,0.0 -73.983973,40.748934,0.0 -73.987733,40.744149,0.0 -73.992177,40.743465,0.0</coordinates></LinearRing></outerBoundaryIs></Polygon></Placemark>

Displaying KML | Maps JavaScript API, preserveViewport specifies that the map should not be adjusted to the bounds of the KmlLayer 's contents when showing the layer. By default  Writing the KML feature data to the sidebar. More information. This tutorial shows you how to display information of a KML file in a Google map and sidebar. For more information on using KML files in maps, read the guide to KML Layers . Try clicking a marker on the map below to see data in the sidebar. The section below displays the entire code

A <Polygon/> has to be a child of either <Placemark/> or <MultiGeometry/>, but not of <Document/>

KML and GeoRSS Layers | Maps JavaScript API, KmlLayer(''); service accessible by the Intranet, the geometries were not displayed subscribed to the Google Groups "Google Maps JavaScript API v3" group  The KmlLayer renders KML and GeoRSS elements into a Maps JavaScript API tile overlay. Overview. The Maps JavaScript 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.

My mistake was having HTTP auth enabled on my server, which was preventing google from requesting the KML file. I guess it is not done client side.

I get a message that it's an invalid KML file and unfortunately neither of the online KML validator tool

I had this kind of issue (kml layer not displaying) because the url (or maybejust the file name) was too long. With a shorter url it was working.

Plotting KML files onto a Google Map, My goal is the following: I have a Google Maps API showing a kml layer If the KML is not too complex, use a third party parser (geoxml3 or geoxml-v3, which  Since you have already invested in Google Maps development, I would highly suggest pushing all of the data into Google Fusion Tables, which can then be parsed onto the map in a similar way as KML with incredible performance (see WNYC Fusion Tables app). Consider it an upgrade to KML without having to drastically modify the front-end.
