@Adrian,

Since the development of kmlmapserver mapfiles syntax has changed slightly, this is probably the reason why kmlmapserver does not very well with latest mapserver.

And to tell you the truth, we will probably not invest much more time in this project. The idea behind kmlmapserver was to have something at hand while a true KML support was being integrated into mapserver core. This did not happen so far.

Unfortunately, we have not any paying customer to fund the development of kmlmapserver and we did don’t receive any donation until now.

If anybody has a budget available to invest on further tests and development on kmlmapserver, we would be happy to continue our work on this project.

Hi there, I’ve got a working MapServer installation with both WMS and WFS running happily. I’ve installed KMLMapServer and it’s serving files. Which is great! However, the files only contain the layer names and not any data. I see a couple of other people are experiencing the same issue. Has anyone worked this one out yet?

Is there any chance someone who has a working installation could post their map file?

Thanks

Adrian

Thats a very fine application,thanks.

I am using Mapserver data from a postgis database.When i use the script it servers a doc.kmz file alright but opening it in google earth it seems there is no data inside.The file is 4kb.
Could anyone please give me a hint on what could be the problem.

Thanks

Well, this problem only affects linux google earth 5.1 version.
A solution exists, described here :

@Lionel:

yes we have indeed had some problems due to a KML spec change (KML parser has become more strict), we have done some changes in our other internal libraries but we didn’t find the time to fix kmlmapserver.

I received a patched version three days ago but I don’t know if this version fixes your problem, if you have time to work on this issue and if you are willing to commit back your findings I could send it to you for testing.

Also: are you sure the problem is not in your Google Earth build ? I’ve observed a similar issue under a 64bit linux distribution and it was just a library problem.

Hi,
I try to use kmlmapserver with GoogleEarth v5.1.
I still work with Google v4.2, but I have troubles with the last version. Polygons are not correct and points are not correctly represented (all points have the same coordinates).
Have you heared about changes in KML specifications that could append with kmlmapserver ?

Thank you for your answer Alessandro.

It was not too complicated …
I added a parameter “kmxfilename”, I changed get_request () to read it and I changed send_header () and send_stream ().
Everything is ok!
Thank you for this script.

@Vincent

no, you need to modify the code and add a new metadata and parameter for the file name.

Not an easy job though.

Hello,
I want to use KML Mapserver but I need to control the file name generated by KML Mapserver. By default, the file name is doc.kml (or doc.kmz). Is there an hidden parameter for that ?
Thank you for this component !
