I've gotten a ton of requests asking how I manage to find massive POI building locations and figured I just share what I've learned.
father.io poi buildings are, of course, generated using the real world buildings. The type of building is determined by the industry in which the real world building belongs to.
Solar cell: resturaunts, fast food chains, truck stops, cell phone stores
Coin generators: retail stores, vending machines, department store, auto repair shops
Banks: banks, credit unions, money exchanges, western unions, money grams, tax services
Multi-Resource Buildings (white/yellow) - these are rare and hard to find but the ones I've found come from these buildings: Concert Pavillion, Ampetheatre, Starbucks (Large Flagship style stores), DutyFree Stores
