You could simply add features of each layer to your 3rd layer. If you need a copy of features, rather than simply adding features from one layer to another clone them first.
From: [email protected] [mailto:[email protected]] On Behalf Of Brad Spencer Sent: Monday, October 17, 2011 5:12 AM To: 'openlayers users' Subject: [OpenLayers-Users] multiple vector layers List, I have a single markup vector layer [layer1] and I want to add a JSON vector layer [layer2] and work on the markup layer [layer1] snapping to both layers[layer1 & layer2]. This works fine so far. Now I want to merge the vector from both markup [layer1] and JSON loaded layer [layer2] into a single layer [layer3] for saving into a new JSON file. I have looked at OpenLayers.Layer.Vector.RootContainer as it looks like it should allow me to look at multiple layers and I assume I can set it up to save the layer3 as well. I have not been able to make it work so was wondering if there are any examples out there I could have a look at? Cheers, Brad....
