[kml-support] NetworkLinkControl not updating in Google Maps, works fine in Google Earth

[JohnRiz]

Hello,

I hope someone can help..

I have a KML file, which loads two other KML files via NetworkLinks
The loader file is here:
http://bumbleware.co.uk/loader.kml

The first KML that loads up is going to draw some shapes, to keep it
simple I have just one shape in there now, the shape has an id of
"shape1". This shapes file can be found here:
http://bumbleware.co.uk/shapes.kml

Then I want the second KML file from the loader to update the shape
from the first file, so I have a KML file "updates.kml" with a
NetworkLinkControl referencing the first shapes file, and trying to
rename the shape.
This file is here:
http://bumbleware.co.uk/updates.kml

The whole thing works perfectly when I load the single loader file
into Google Earth, the shape is drawn, then the name is changed by the
updates.kml file.

However when I try and do this using Google Maps (either v2, or v3)
the loader only manages to load the shapes file, it looks like the
updates.kml is not taking effect.
Does anyone know why this might be?

Both v2 and v3 versions of the google maps efforts can be found here:
http://bumbleware.co.uk/mapsversion2.htm
http://bumbleware.co.uk/mapsversion3.htm
You can see in both cases the Shape1 does not get it's updated
description from the updates.kml file, like it does when the loader is
opened in Google Earth

Thanks in advance!

John

Addition:
I realised someone might point me in the direction of the MIME types,
since the I can't change the httpd.conf on the bumbleware site so I
made a mirror copy of the site on IIS where I have correctly set the
mime types. It's running here:
http://demo.qresearch.org/mapsversion3.htm (loader and other KML files
updated to work from this domain too!)

Problem is the same with the mime types correctly set. i.e. Works in
GE, not in Google Maps.

Ta!

Another addition..

I've found some documentation that says updates are only supported in
Google Maps for styles:
http://code.google.com/apis/kml/documentation/kmlelementsinmaps.html#notes

"
<NetworkLinkControl> partially <Update> and <expires> partially
supported (see Notes section above)
<Update> partially only style changes, not <Create> or <Delete>
"

So I've changed my code to simply update the shapes style by changing
the styleUrl
It's running here:

http://demo.qresearch.org/2/mapsversion2.htm

It still doesn't work though, the polygon remains the style that it is
set in the initial file (a blue circle), rather than the update that I
want to apply (yellowLineGreenPoly)
I'm out of ideas and clutching at straws now. I'd better stop posting
and let someone respond...

No map in FF2 ; I think because of the use of self-closing tag
<script ... />
See
http://www.webmasterworld.com/html/3614746.htm

I note that your updates.kml contains indirection, referring to a
style in another seperate KML not previously referred to
(styles.kml). Maybe the GGeoXml parser can't cope with that depth of
indirection, it does have many limitations. What happens if you
change colour style directly in updates.kml?

[JohnRiz]

Cheers Rossko
I've fixed the </script> for FF now, well spotted.

I tried a few ways of changing the colour style, both using styles
embedded in update.kml and also in shapes.kml, neither worked in
Google Maps.
I'm now thinking that because it works perfectly in Google Earth,
maybe the documentation for Google Maps isn't quite right, and that
changing the style is not supported afterall.
I hope I am wrong and someone can point out what I've missed though...

My fallback option I guess would be to embed a Google Earth viewer
object in the page...

Still looking for an answer I came across this person:
http://groups.google.com/group/kml-support-server-side-scripting/browse_thread/thread/e5eea4917e3ca409/dda403e6baa42463#dda403e6baa42463
..who seems to be having the same issues as me, i.e. Style updates
working in GE not GMaps.
Although they are changing the style in a different way (using a
targetId on the style element)

It would be good to hear from someone who has managed to change the
style of an element using NetworkLinkUpdates in Google Maps, I would
have thought it was a pretty common thing (1 static file holds shapes,
the 2nd is used to dynamically change their colour based on some
changing data)

Cheers!

Hi John,

Any chance you found out what was going wrong?

I have a slightly different problem -- updating a StyleLabel tag in GoogleEarth is not doing anything for me.

I'm gathering information for now ;)
