Level 20 cells are used to generate Pokémon spawns.Level 17 cells are used to determine whether an Ingress portal will be imported into Pokemon GO.Level 16 cells are used to render the overworld map, rendering Gyms and Stops within a 500-meter radius of your current location.Level 15 cells are used to block military zones from the game.Once you reach a certain threshold of PokeStops in the L14 cell, the game will convert one of them into a Gym Level 14 cells are used to determine the number of gyms in a cell (see above).Level 13 cells are used in the EX Raid system distribution, as explained in our comprehensive guide on how to trigger EX Raids.Level 10 and 11 cells are used to determine the current weather conditions.Level 10 cells are used to determine Pokémon caught location.Level 20 cells are used to decide whether or not a gym that is on the boundary of a park is eligible for EX raids.Ī list of confirmed S2 levels and their role in Pokémon GO:.Only one gym in each Level 13 cell can host an EX raid in any given week. EX raids are controlled by Level 13 cells.The number of PoIs determines the number of Gyms in Pokemon GO: Each level 14 cell contains 64 Level 17 cells, so up to 64 PoI in Pokemon GO. There can be multiple Ingress portal in an L17 cell, but only one Point of Interest in Pokemon GO. Only one PokeStop or one Gym in a Level 17 cell.Here are how S2 cells influence Pokemon GO: Trainer Tips has an excellent video on the subject: As you will see from the list below, S2 cells are the secret underpinning of everything you interact with in Pokémon GO. Up to this date, the Pokémon GO research community has managed to identify several ways in which Niantic uses the S2 cell system to build and enhance our game experience. This is how Level 12 cells are organized over Split, a beautiful city in Croatia: Level 12 S2 cells (visualized over Split, Croatia) they are indexed and each cell has a unique number, which is very handy for software developers.they are hierarchical, or in other words, a larger cell can be broken down into multiple smaller ones.they come in various sizes called “levels” (higher level = smaller size).S2 cells are not “magical” in any way, but they do have a few useful properties: This is one of my favorite libraries at Google. It internally uses 64 bit numbers to uniquely identify cells, with sizes ranging from millimeters to hundreds of kilometers on a side, using projections of spheres onto the surfaces of cubes, quadtrees, and enumeration of positions on Hilbert space filling curves. Within Google we use a clever library built by Eric Veach to identify regions on the surface of the earth. Jeff Dean, a senior Google fellow, has shared the following about the S2 cell system: We will not go into how Hilbert’s curve works, but, in a nutshell, it allows you to fill any 2D space with a single, uninterrupted line. S2 cells were first produced in 2005 by Eric Veach, a Google engineer who used David Hilbert’s “space filling curve” to translate Earth’s shape into 2D space. You can think about them as tiny units of geography that computers understand and developers love to use. S2 cells are a mathematical mechanism that helps computers translate Earth’s spherical 3D shape into 2D geometry. This article explains how S2 cells work, what are S2 cells and how S2 cells work in the context of Pokémon GO.
