MapTool

A mapping application written in Ruby with Sinatra.

The project’s shape is still open — this is the initial scaffold.

Status

Early scaffold. The web application serves a vector map (MapLibre GL JS), with an online style and an optional offline style backed by a local PMTiles file, an animated RainViewer radar overlay, GPX upload/display (points and tracks, organized in folders), and a live position marker from a local GNSS receiver via gpsd.

Requirements

  • Ruby (see .ruby-version) and Bundler

Getting started

bundle install
bundle exec puma -C config/puma.rb

Then open http://127.0.0.1:4567 in a browser.
