FalconView (#1) - Network links (#519) - Message List

FalconView KML should support the onInterval refresh mode in KML. See  http://code.google.com/apis/kml/documentation/kmlreference.html#link If it doesn't refresh when it should, let me know.

What version of FalconView are you using? Can you send me your KML so that I can look at it and offer suggestions?

Joel, a time-static KML does work. The KML we will be creating will be updated approximately every 5 seconds. We'd like the display to change automatically without having to manually reload it. Would you explain how a custom overlay could accomplish this? I'm brand new to FalconView, and unfamiliar with most of these concepts.

Michele, does your KML file not work in FalconView? It should work in FalconView 4.2.1 and beyond. What version of FalconView are you using? If it is older than 4.2.1, I can ask around for other ideas.

You could also write a custom overlay, if you can program. The custom overlay samples that we have on this web site could be adapted in a few hours of time.

@joelodom Thank you again for your response. What I am ultimately trying to do is to automatically update points on a map. Imagine I have something that is sending me real-time position information. I want to parse that data stream and update FalconView accordingly. In Google Earth I would do this with what they call "network links" (I apologize for the confusion, I thought it was a universal term). In GE I can run a script that updates a KML file, and the "network link" is merely a pointer in GE to that file that allows me to set properties such as refresh rate. How would I do this real-time/near-real-time updating in FalconView?

This means that network links within KML will be followed when FalconView loads KML. We don't (yet) have a full capability to edit KML, which is what you seem to be looking for. If you want to create KML with an embedded network link, you can do it in Google Earth and view it in FalconView, or you can create one by hand. See  http://code.google.com/apis/kml/documentation/

Thank you for the response. The reference in the FalconView docs is here right under the section titled "KML Support": http://www.falconview.org/trac/FalconView/wiki/OpenSourceFeatures

"FalconView Open Source can display KML and KMZ files. Network links, ground overlays, screen overlays and styles are fully supported. 3D models are not supported."

In Google Earth, if you open the "Add" menu, Network link is the very last option. If you click on that, in the dialog that opens up, you can Browse your file system and select a file you want to link to. You can also go to the third tab and specify how frequently you want to refresh. With this set up, you can make changes to the file and Google Earth will update itself automatically.

Thanks!

I'm trying to figure out what you want to do. Can you paste the text from the feature page or explain more what you mean by a network link? I'm very familiar with Google Earth and KML, as I implemented KML in FalconView, but I don't quite understand what you mean in the context of a network link for FalconView.
