KML GroundOverlays

[WilliamHenson]

Hi,

First off, my apologies if this has been answered elsewhere if if I am asking in the wrong forum

I have started programming a Silverlight application where we show a KML file with a ground overlay.  This is using the esri:KmlLayer tag but none of the images referenced in the KML file will render.  Have also tried using a KMZ file and also using a full path to the image instead of a local reference in the KML/KMZ file.  Any lines or shapes etc work fine, just ground overlayed images have issues.

Has anyone seen this issue before or know of something that could fix it?

Cheers
Will

Which Silverlight ArcGIS API version are you using?

Support for GroundOverlays has been added in 2.3.

Note also that your map must be in geographical coordinates to display GroundOverlays. At this time, GroundOverlays are not automaticllay projected in the map coordinates.

Hi,

Thanks for the reply.  It ends up I was battling 3 issues - (1) the geographical coordinates, (2) the fact that gifs would not display (other formats are fine) and (3) that KML files that are referenced by other KML files wont show.

Is it possible that #3 is a known issue?  KML files can reference other KML files with no problems (apart from loading time) in Google Earth

Cheers
