marine traffic kml

philippschnetzer — Mon, 19 Dec 2011 14:52:27 GMT

Any ideas why this won't work? It does bring up some layer names and such in the TOC but no info will appear on the map...

<layer label="marine traffic" type="kml" visible="false"
                   url="http://www.marinetraffic.com/ais/ge_marinetraffic.kml"/>

I'm using FV 2.5...and my web server is setup for kml/kmz mime types...

Thanks!

clicking the link on the marineTraffic website gives 404 - File or directory not found message.

Hmmm....the link was working for me when I was testing it, must just be down temporarily...

here's the site where it 'can' be accessed:

This might have something to do with it not working.

Ah I see...that could explain it! Where did you find that error message...firebug?? Is this something that could be changed in the code to allow for a larger size kml?

Fiddler 2

I looked for a way of increasing the limit but couldn't find anything. It must be part of the compiled source.

I'm trying to limit the load using <Region>, but that hasn't worked yet. Still tinkering...

Do you have any idea what this means? :

serviceurl�??Optional, URL to your own utility service for converting KML files to features. [Added in version 2.5]

I found the above quote here: http://help.arcgis.com/en/webapps/flexviewer/help/index.html#/Layer_tag/01m30000000p000000/

...does this mean you can somehow link to a kml in arcmap and publish it using arcgis server and use that service instead?

You can do KML to Layer for instance, but I think it's a snapshot. I believe it doesn't honor the Dynamic nature of the KML Network. You can also use the AGS Manager to publish a KMZ Network link. (which is what I did)

I also loaded the KML in Arcmap (KML to Layer), and it is very slow(large). Someone smarter than me may have a better idea.

btw, I did get <Region> to work in the KML file, but unfortunately, once you hit the set spatial box, it loads the entire feed, not the singular Region I hoped for. So if the size is indeed the problem, this will not fix it. Works great in Google Earth 😞

Thanks for your continued effort! Maybe I will give the kml to layer a try - but as you say if it's not dynamic it's pretty much worthless for this very dynamic dataset! Thanks again, Happy Holidays!

Phillip,

I was hoping one of the API team member would chime in on this... But as far as the bits and pieces that I know the service url is for when esri distributes the KML utitlity that converts the kml to a featurelayer that previously was only available and hosted by esri. This is just hear say but I believe that the method to receive the KML utlity service was going to require you to contact esri customer services and request it. You would then install it on your web server and point that attribute to your server and then the requirement for have public KMLs goes away. Now once again this is what I believe to be true from my bits and pieces of knowledge.

Thanks for the info Robert.

So arcgis.com was creating the features. And if we can host the util/server ourselves, we can increase the limit, maybe?

200 OK (text/plain)

I would stay clear of KML Network until this bug gets fixed:

It's referring to the KML utility that converts the KML feed to a feature layer. This utility service is part of ArcGIS Portal. If you have ArcGIS Portal, you can use its utility service instead of the one on ArcGIS.com.
