Usually you will look at a diorama or a model railway layout from the bird's
eye view - an aspect you should take into consideration when planning your
project. You want to build your own miniature village? So first check some real
air photographs of the original or at least similar villages and find out how
buildings, streets and places are arranged in reality.
You will find aerial views of almost every spot on our planet on maps.google.com (requires fast internet access). Most of the pictures provided are really breathtakingly detailed, but high resolution is not (yet) available everywhere.
