Ecumenopolis mapping question

Hi there, do anyone know if there is any good backdrops for mapping on an ecomenopolis (e.g. Coruscant, Nar Shaddaa etc.)? What I'm looking for is topside views of cities that i can map over, for example when making a bridge between two buildings where you see the vertigo inducing depth of the city under.

Try  Cyberpunk Chronicles: Downtown City Circuit or CYBER CRUNCH Sci-fi Warehouse Tile Set possibly  Compound Quick Encounters 1

All good sets, (Already have two of them since im a roll20 shoppaholic), although i more meant like a picture as background behind the actual map to see through windows etc. but not something the players can interact with other than see. (Imagine the movements where they see the city spreading out through the windows or look down as they hang over a balcony and see how far they would fall)

My suggestion would be to take one of those into an image editor and apply a blur filter, to simulate depth of field. This would really make the sharp focus of a balcony or bridge the characters are standing on pop out.

Humm... yeah, that'd work, thanks :D

In the past, I’ve used Google Earth to get an overheard shot between a few buildings in New York or Chicago and built a map over the top of that.
