Installation

npm install @geolonia/osm-miniplanets

Usage

tileToMiniplanetId

Returns the miniplanet ID for a given tile coordinate. Returns undefined for zoom levels below BASE_ZOOM (6).

import { tileToMiniplanetId } from '@geolonia/osm-miniplanets';

// Pass tile coordinates as [x, y, z]
const id = tileToMiniplanetId([906, 404, 10]);
console.log(id); // '14'

// Returns undefined for zoom levels below BASE_ZOOM (6)
const id2 = tileToMiniplanetId([0, 0, 5]);
console.log(id2); // undefined

generateGeoJSON

Generates a GeoJSON FeatureCollection containing all miniplanet subdivision boundaries.

import { generateGeoJSON } from '@geolonia/osm-miniplanets';

const geojson = generateGeoJSON();
console.log(geojson.features.length); // 18

calculateMiniplanetTiles

Returns the tiles that make up each miniplanet, merged into the largest possible tiles.

import { calculateMiniplanetTiles } from '@geolonia/osm-miniplanets';

const tiles = calculateMiniplanetTiles();
// tiles[0] = tiles for miniplanet 00
// tiles[1] = tiles for miniplanet 01
// ...

Constants

import { BASE_ZOOM, SUBDIVISIONS } from '@geolonia/osm-miniplanets';

console.log(BASE_ZOOM); // 6
console.log(SUBDIVISIONS.length); // 18
