The "City Lights" layer above is created from a single web accessible
|
|
image. If you construct it without any resolution related options,
|
|
the layer will be given a single resolution based on the extent/size.
|
|
Otherwise, it behaves much like a regular layer. This is primarily
|
|
intended to be used in an overview map - where another layer type
|
|
might not make a good overview.
