This gist describes how to download a map for a custom region and serve it on a website.

It uses the Protomaps Basemap but the same workflow can be used with OpenMapTiles or Shortbread.

The download links are:

Outline

Define the outline of the region you want to have a map of with https://geojson.io.

With this website you can draw a polygon and get the geojson of it.

Copy the geojson from the right panel to a files called outline.geojson.

pmtiles CLI Tool

The pmtiles command line tool allows you to download a map extract for the region defined in outline.geojson.

The pmtiles tool is distributed as a binary executable on the github releases at https://github.com/protomaps/go-pmtiles/releases

Download the pmtiles tool for your machine:

Download Region

With the pmtiles tool we can now download the pmtiles file for the region defined in outline.geojson:

pmtiles extract https://build.protomaps.com/20240721.pmtiles protomaps.pmtiles --region outline.geojson

You might need to change the date to the current date...

Serve the Map

Now download the files below index.html and style.json to the folder where you have the outline.geojson and protomaps.pmtiles file.

Serve the files with a http server that supports range requests, e.g., npx serve --debug . -p 3000 --cors.

Open a web browser at http://localhost:3000/ and you find your map:
