Meteorite landings on Planet Earth

This is a demo project demonstrating how to setup a pipeline to build and use static vector tiles as described in the accompanying blog post.

Check out the live demo here!

Setup

Dependencies

Make sure you have installed:

• tippecanoe
• ogr2ogr
• Node.js

Building tiles

Use artifacts/Makefile to build the tiles:

TILES_HOST=https://my-host.com make -C artifacts

This downloads the necessary data, cleans up and generates a tiles folder in the project root containing a nested directory structure with the tiles.

If you don't provide a TILES_HOST, http://localhost:5000 will be used by default.

Once you have the files downloaded, it's generally faster to just run the build-map-tiles command:

TILES_HOST=https://my-host.com make build-map-tiles -C artifacts

Development flow

You can start a dev server on http://localhost:5000 by running the dev-server.js file on the root.

node dev-server.js

The script serves map tiles with the correct Content-Type and Content-Encoding headers so you can experiment and tweak the build pipeline locally.
