[Geoserver-users] Why does KML link give me KMX ?

Hello,
I am trying to include a layer in OpenLayers. I have set up the POSTGIS connection to my layer but when I click on the DEMO page and KML I get downloaded a KMZ file.

http://localhost.no:8080/geoserver/wms/kml?layers=kulturminner_ns:boplass

I checked on another geoserver and there the link downloads a KML file. What am I doing wrong? Is it something to do with the proxy.cgi?

Hi Asle,

it is actually a KML file, it just has the .kmz extension. We used to compress the KML output by default, I guess we don't anymore. Could you file a jira issue?

(The "wms/kml" part of the URL does not imply the format, it only tells GeoServer this is a KML-related request.)

The KML reflector is optimized for use with Google Earth, which means
that it returns a compressed kml file with a regionated hierarchy
whenever possible. If you want the raw XML, you can either:
* request a non-regionated, non-compressed KML file by appending
'&mode=download' to your request parameters, or
* go through the "real" WMS (geoserver/wms) and set format=kml.

Hope this helps.

Hi,
I understand that I am using GeoServer 1.7.3 and that the output is KMZ always?
The KMZ file I download from the GeoServer demo page zooms to the correct area when I open it in Google Earth. But all the markers were gone! So I found out that I had put this in Config-Server:

Proxy Base URL: mydomainame.no:8080

When I left that field in config empty I get the same KMZ file but now with correct markers. I am confused as to how this affects the serving of KML/KMZ to OpenLayers. Here is the code from my html which shows no data, only the name of the layer.

var kml =new OpenLayers.Layer.GML(“KML kulturminner”, “http://naturkart.no:8080/geoserver/wms/kml?layers=kulturminner_ns:gravminne&format=application/vnd.google-earth.kmz+XML&transparent=true&”,
{
format: OpenLayers.Format.KML,
formatOptions: {
extractStyles: true,
extractAttributes: true
}
});

And I can see it is loaded in Firebug with this request:

url http://naturkart.no:8080/geoserver/wms/kml?layers=kulturminner_ns:gravminne&format=application/vnd.google-earth
.kmz+XML&transparent=true&

And this response:

Aha. I think I found out the one with Proxy Base URL. I forgot the “http://” - Now my KMZ files load correctly in Google Earth at least!
