Calling all researchers, land managers, and FOSS4G hobbyists who need a modern web map. Using just a Github account, you can make a web map that is simple and free to deploy, is totally customizable, can be integrated into your CMS or modern web stack.
In this workshop, we will walk through how to build a map inside a GitHub repository, hosted with GitHub Pages, and built entirely with open source tools.
Workshop materials and individual modules with step-by-step instructions are under construction at https://github.com/mizmay/standalone_web_maps_foss4g2025 and viewable at mizmay.github.io/standalone_web_maps_foss4g2025/.
Attendees are encouraged to come prepared with a laptop, having completed at least step 1.
Key concepts / technologies:
- PMTiles: because they work via HTTP, PMTiles (portable map tiles) do not require a map server to deliver tiled map data to your browser.
- Protomaps: is a global basemap stored in PMTiles that can be downloaded from a bounding box and customized to meet your needs.
- Overpass: is an API and querying language for OpenStreetMap that can be used to extract select data you want to use to add context and fidelity by styling them within your basemap
- GitHub Pages: provide a built-in web hosting platform for any Github repo. Provided your repo is under 1 GB of data, achievable for most project or site-level maps, this is all you need to host your map
- Maplibre GL JS: is an open source, vector tile map rendering library for Javascript. It supports PMTiles and can be used to control how your data from PMTiles and other sources is rendered and displayed.
