randy aa2b96ac70 Add a "user overlay" tool: click the map, save a note
New map-corner "Add note" control (public/js/notes.js), mirroring
measure.js's click-to-place UX. Click the map, write a short note,
pick an existing .geojson layer file or name a new one — saved via a
new GpxStore#append_feature (grows the target file in place, unlike
save()'s always-disambiguate-the-filename behavior) through a new
POST /api/gpx/notes route.

No new rendering path: a note is just another point in a .geojson
file the Tracks panel's tree already lists, checkboxes, and pops up —
visibility toggling ("layers") comes for free from that existing
machinery, per-file, with no changes needed there.

Points only for now — a polygon mode would need gpx.js's point/line
split taught a third Polygon bucket first, or a saved polygon
wouldn't render back on reload (see TODO.adoc).

Covered by new tests: GpxStore#append_feature (create/append/missing-
path/filename-safety) and the /api/gpx/notes route (auth gate, create,
append, malformed/missing-geometry rejection, 404 on a missing
target). Full suite: 97 runs, 0 failures.

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.
