Pokémon GO spawns are usually encounter at certain areas that correlate with Open Street Map data. Our initial research showed that Nests also correlate with certain OSM (Open Street Map) areas. These areas are marked on Open Street Map as:
- Recreation Grounds
- Golf courses
Basically this tool shows areas in your location that can produce possible spawns and nests. It does not guarantee that Pokémon will be found in the highlighted area but it is a good indication on where they might be. Since nests and spawns are generally found in parks and recreation areas, this app is very helpful and it is very easy to use.
