Lots of them! Pokemon go has a few main biomes with lots of other factors to determine what spawns. Main biomes are grass, city, mountain, and water.
Then you have other tags for things like parks and paths, which give special spawn points. Parks have rotating habitats for one particular species and can have EX gyms. Paths will spawn Pokemon along them with a few unique species.
Regional spawns occur as well, with some continents or countries having one or more special species unique to it. And rather than a strict limit, some species are much more common in certain latitudes.
Beyond that are some tags that prevent spawns, like military bases or wetlands, places you aren’t encouraged to just walk around.
Lines tagged highway=footway that also carry the tag bridge=yes do not generate additional spawn points. Critically, this encompasses all boardwalks, which are correctly tagged bridge=boardwalk.
Lines tagged highway=footway do not provide a spawn point exception through the area blocked by natural=wetland as they do for natural=wood. It’s possible that this is an extension of the issue with bridge=yes – I have no local examples without both tags.
Areas tagged landuse=basin block all spawn points, despite being used correctly to tag the contemporary practice of building a stormwater retention system beneath a city park. These areas are rendered as water in-game, but do not seem to influence Water spawns, although more data would be helpful in determining this. (OSM also has issues rendering basins.)
Areas tagged leisure=nature_reserve do not nest. Could be intent, could be oversight, but seems like an odd exception, as the distinction between a park and a preserve is fluid – at least in the US. The same is true for areas tagged landuse=winter_sports, the correct tag to describe a ski resort, and areas tagged leisure=dog_park.
Areas tagged amenity=prison do not block all spawn points. Since this is the correct way to tag a prison or jail – which is to say, a high-security facility where people probably shouldn’t be chasing Pokémon – this seems wrong.
Lines tagged waterway=river, waterway=stream, and waterway=ditch are not rendered on the map despite influencing Water spawns in nearby spawn points. The same is true for areas tagged natural=wetland and points tagged amenity=fountain.
Lines tagged power=line and power=minor_line do not influence Electric spawns in the way that streams do with Water Pokémon. More of a missed opportunity than anything. You could say the same with railway=rail and Steel or any of the more specific OSM building tags the game references to seemingly no effect: leisure=stadium, amenity=cinema, tourism=hotel, and so on.
Lines tagged highway=track show up visually as paths, despite being intended to represent vehicle tracks that fall short of the qualifications for being an unpaved road. They do not generate additional spawn points, so this is assumed to be an error with the in-game renderer.
Lines tagged highway=service and service=driveway render as roads on the map, which are not to scale. This is especially glaring if houses and garages are mapped. Ideally, there probably should be a thinner style of road for all service roads, tracks, living streets, or any other highway designation where vehicles are likely to encounter pedestrians.
