Multiple layers in Overvew Map dijit

EdSaunders — Wed, 13 Jul 2011 05:47:11 GMT

Hi there,

Just wondering how I can load more than one base layer into an overview map dijit? I'd like to add a tiled layer and, on top, an operational layer that is loaded in the main map?

Thanks for any assistance.

I don't think you can add more then one layer on the overview map. An alternative approach would be add another map control on the page acting as a overiew map and using Map's onExtentChange event to synchronize the extents and behaviors of the two maps.

Heming, thanks for your comments. Yeah I was thinking that's what I'd have to do. I reckon the ability to add more than one base layer to the overview dijit would be a good enhancement to the API.

Cheers.
