[OpenLayers-Users] Make the base layer empty or blank

[Matt Williamson]

Justin,

I've done something sort of like this before--I just made a small  
transparent GIF image and set it as a Layer.Image as the base layer  
(stretched to some arbitrary size and bounding box). You might even be  
able to set it to not be visible in the Layer Switcher, but I forget  
the property or method to set to try that (and it might not work). The  
only thing you'll have to do is configure that "blank" image layer  
with the appropriate scales or resolutions that you want your other  
layers to conform to (or I think you can set these on the map  
directly, but I haven't tried that yet).

Probably a better way, but that has at least worked for me.
