Keeping your initial assumption of default visibility, you'd get at least 6 tiles loaded, that makes for ~600 sq miles, wich is ~1/8 of the LA Metropolitan Statistical area, 8*340k ~ 2.7 million buildings for a population of ~12.8 million, that gives about 4.75 persons / building. Assuming 1/3 of the buildings are actualy represented as commercial/office that gets us to ~7persons/building or around 2households/building, which would be about right if it were residential, but is of course wrong for the apartment buildings; that is not the algorithm that's at fault, that's the underlying representation of the terrain (which should have just the core of the bigger cities in the area mapped as urban, and te rest as residential/town) Disclaimer: All this ignores the fact that Stuart was actualy using the live weather hence we don't actualy know the visibility/ number of tiles loaded, that we don't know which way he was facing, the fact that in reality just 1/6 of the surface loaded at startup is dense urban area, while the rest is residential, and wide spaced commercial/business area, etc. Emilian ------------------------------------------------------------------------------ Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.
