combine-tiles

Combine map tiles into a single large image. Uses the great sharp package for efficiency. Similar to abacus and merge-tiles.

Installing

npm install combine-tiles

Usage

Check out the example directory!

const combineTiles = require('combine-tiles')

const size = 300
const tiles = [
	{x: 0, y: 0, file: '/path/to/0-0.png'},
	{x: 1, y: 0, file: '/path/to/1-0.png'},
	{x: 0, y: 1, file: '/path/to/0-1.png'},
	{x: 1, y: 1, file: '/path/to/1-1.png'}
]
const dest = '/path/to/combined.png'

await combineTiles(tiles, size, size, dest)

You may want to use tilebelt to convert bounding boxes into [x, y, zoom] tiles or tile-cover to generate a list of tiles in a bounding box.
