Extended OFFLINE_THEME's color-role overrides to lean into the warm,
Harpers-Ferry-Center-derived look of the National Park Service's own "Park
Tiles" cartography, rather than the cooler default protomaps-themes-base
palette. A handful of values (background, the park/protected-area green, the
two road-importance tiers, the park-boundary line color) are the genuine
paint colors pulled from a public Park Tiles style JSON — the "Imagery"
variant is the only one of NPS's four styles served from a plain,
unauthenticated URL; "Standard"/"Slate"/"Light" resolve through Mapbox
Studio's private API with an access token, which isn't something to
piggyback on even though it's technically visible in their own JS bundle.
The rest of the palette (forest/scrub greens, water, sand, buildings) is
reasoned to match that same family rather than sourced.
Recreating the color choices is fine — that's not the kind of thing a data
license restricts. What stays off-limits is their actual tile service: its
OSM/terrain layers are licensed through Mapbox Atlas, a commercial,
non-sublicensable data service scoped to NPS's own use.
Two things pulled in from github.com/nationalparkservice/npmap5-plugins:
- A "Home" button (public/vendor/npmap-home-button/, NPS's own MapLibre
control) pinned to the app's CENTER/ZOOM, sitting top-left on the map. Now
that the URL hash permalink can open the map at any view, "current view"
and "the default view" aren't the same thing anymore, so a quick way back
to the default is worth having.
- npmap5-plugins bundles a newer, actively-maintained version of the same
NPS symbol-library already used for POI_ICONS (confirmed by its
maintainer to be the designated replacement for the older standalone
repo: nationalparkservice/npmap5-plugins#4), with a much larger icon
vocabulary and a simpler CC0 (public domain) license. All 25 icons
already in use came back byte-identical from the new source, so this
just repoints their attribution — but it also has icons the old repo
didn't: `forest` (POI_ICONS) is now the official "wilderness" pictogram
instead of hand-drawn, and three of the five previously icon-less
Services/Activities tags (wifi, mobile data coverage, winter/snow
camping) now have real icons too. Only bakery and vehicle wash still
have no NPS equivalent.
The Online/Offline sidebar icon was always shown, even on an install with
no data/offline.pmtiles — offering a choice that can't actually work.
LayerToggleControl#remove() removes the icon (and hides its panel) once the
existing /api/offline-tiles check confirms there's nothing to switch to; a
transient failure of that same-origin check leaves the switch as is rather
than guessing, since that's the request itself failing, not evidence
offline tiles are unavailable.
Panning/zooming now updates #map=<zoom>/<lat>/<lon> in the URL, and loading
a URL with one already opens at that view instead of the default center —
so copying the URL bar shares the exact spot someone's looking at, and a
page reload doesn't lose the current view either.
This is MapLibre GL JS's own built-in Hash control (hash: "map" on the Map
constructor) — it already does exactly this, replaceState and all, no
custom code needed.
Track properties gain activity_type (FIT: sport enum from the
session/sport message, Garmin's own table; GPX: <trk><type> passed
through as-is) alongside the existing distance/elevation/duration.
Clicking a track line now opens a bottom panel with a chart per
metric the track actually has (elevation always; speed/cadence/heart
rate only when present — FIT's record fields or GPX's device
extensions). TrackStats.build_profile computes cumulative distance
the same way for both formats so they're directly comparable. One
pointermove listener drives a synchronized crosshair across every
chart, a single tooltip listing all series, and a map marker at the
hovered point's position — hovering the chart shows where on the
track that moment was.
Clicking a LiveTrack session now fetches and draws its track (line +
latest position). Garmin's own API 403s any plain server-side request
(Cloudflare bot protection), so LiveTrackClient fetches the session
page instead and pulls the track out of the server-rendered data
embedded in it. The webhook now captures the session's token too,
since the id alone isn't enough to fetch anything.
A Gmail-watching Apps Script (documented in docs/deployment.adoc) posts
the session ID from each LiveTrack email to a new webhook, which stores
it in data/livetrack.json; a new sidebar panel lists what's been
received.
Remove osmand-style.js (the per-layer color-patching approach) and its
docs entirely — back to the plain OpenFreeMap "liberty" style online,
and protomaps-themes-base's stock theme offline as the base.
Offline maps previously had no text labels at all: the
protomaps-themes-base layers() call never passed a lang option, which
is required to include its label layers. Fixed, backed by vendored
Noto Sans Regular/Italic/Medium glyph PBFs (ranges 0-255 and 256-511
only — Basic Latin + Latin-1 Supplement + Latin Extended-A, enough for
accented Central European place names; other scripts won't render
offline). Verified against the actual offline.pmtiles vector layer
schema that the name/name:en/script fields this expects are present.
Also nudge a handful of OFFLINE_THEME color roles (background, water,
wood, buildings, the two road-importance tiers) towards the online
style's actual palette (sampled from its style JSON) so switching
Online/Offline doesn't look like two different apps — deliberately
partial, not the removed full recolor.
Restructure the map controls from MapLibre corner buttons into a left
sidebar of icons with flyouts/panels (radar, GPX, GNSS), matching
OsmAnd's layout more closely:
- Base map and GPX selection are now full-height side panels docked
next to the sidebar (not small dropdown flyouts or a right-docked
panel), opening/closing exclusively via a small shared event bus
(panels.js) so only one is ever open at a time.
- The GPX panel's upload/new-folder controls are now icon buttons in
the header instead of an always-visible dropzone and form; dragging
a GPX file onto the tree, a specific folder, or straight onto the
map itself all upload it.
- New: Maptool::GpsdClient (lib/maptool/gpsd_client.rb) streams live
GNSS fixes from a local gpsd daemon over Server-Sent Events
(/api/gnss/stream) to a marker on the map (public/js/gnss.js) — one
background gpsd connection shared by every browser tab.
- The online map style (public/js/osmand-style.js) is now styled to
resemble OsmAnd's own rendering, applied to both the online and
offline (PMTiles) styles.
Also adds a GeolocateControl (browser geolocation) next to the zoom
controls.
Upload GPX files into a folder hierarchy (traversal-safe path
resolution against the store root), browse them in a tree panel, and
toggle each one's waypoints/tracks on the map. Waypoints render as
clickable points showing name, description and time; bare URLs in the
description are turned into safe links. GPX layers survive switching
between the Online/Offline base map, same as the radar overlay.
Adds rexml as an explicit dependency — it moved to a bundled gem in
this Ruby version and isn't picked up by Bundler otherwise.
Replace Leaflet/raster tiles with MapLibre GL JS: an online OpenFreeMap
style and an offline style built from a local PMTiles archive via
pmtiles.js and protomaps-themes-base (no glyphs/labels offline by
design, see docs/architecture.adoc). Frontend libraries are vendored
locally rather than loaded from a CDN so the app keeps working with no
internet access.
Also add an animated RainViewer precipitation radar overlay (toggle,
play/pause, scrub slider), matching the default time window of the
weather-radar-card Home Assistant integration.
