Elixir has a great set of tools for integrating mapping features into our applications. The best part is that it is surprisingly simple to do so! In a bid to demystify the world of mapping with Elixir, we will use libraries from Hex.pm and the amazing open source mapping ecosystem to live-demo: * creating customized maps using OpenStreetmap data * self-hosting those maps using a one-liner Plug * add custom data to maps from your preferred database * real-time, multi-user map interactions with Phoenix Channels * fetch and process data from online GIS portals (e.g. POIs, street addresses, land parcels) No prior experience with maps or GIS is assumed or required, and the demo app will be made available as open source.
