I think the OP is referring to a statistical spatial model, not a physical (or digital facsimile) model.
His post is asking about MAPPING sightings and then creating a geographical model of the aggregate sightings.
...to create an accurate model ... looking in the sky in the right geographical location...
Something like this (among many others already available, OP):
Google UFO Map
Other sources (pretty much using the same modeling algorithms):.
UFO Maps.com
UFO Maps blog
Slate UFO Map version
This one is good because it includes a descriptive table about the sightings:
UFO Stalker Maps&Data
Of course, if you really wanted the kind of model my good friend Zorgon is referring to, you can have one of your own. Get it here:
UFO Model on eBay
Or, the newer Roswell version:
UFO Rosewell Model on eBay
Many more "models" likes this are in the marketplace.
Again - IMHO - I don't think these are the kind of "models" he was referring to, but rather the kind TPTB are interested in, like this:
