The badge and category glyphs were registered as SDF images (a single alpha
shape MapLibre tints at render time via icon-color) purely so one shared
sprite could be recolored per category. But SDF rendering assumes the
source actually encodes a distance field — a smooth multi-pixel gradient at
every edge — and these were just normally antialiased rasters (a sharp ~1px
transition). MapLibre's SDF antialiasing pass softened every edge as a
result, visibly blurrier than the base map's own icons, worst on the small
category glyph.
The glyph color never varies (always white), so it never needed runtime
tinting at all: _registerCategoryGlyphs now bakes #fff directly into the
raster and registers one plain image per category. The badge color does
vary (arbitrary per-file hex), but a real POI export only has a handful of
distinct category colors, so _registerBadgeColors rasterizes one sharp
image per distinct color actually present in the points being shown,
cached by color, instead of one shared image tinted at render time.
The National Park Service frames its own map symbols (the icons already
vendored in for POI categories) in a rounded square, not a pin — pairing a
pin shape with NPS-style pictograms looked like two mismatched icon
conventions. Switched the marker to a rounded square to match.
This also simplifies the placement code: a pin has to anchor at its tip, so
the category glyph on top needed an offset computed from the pin/glyph
geometry to land in the pin's head. A square has no tip — both the badge and
the glyph layer just center directly on the coordinate with no offset math
at all.
Colored circles for waypoints looked too similar to a base map style's own
small circular POI icons, so uploaded POI data blended into the map instead
of standing out. Switched the marker shape to a pin/teardrop (reusing the
existing WAYPOINT_ICON path, filled instead of stroked) — no base map style
uses that shape for its own points, so it reads immediately as "your data".
Anchored at its tip, the standard map-pin convention, rather than centered
on the coordinate.
Also swapped the hand-drawn category glyphs for the National Park Service's
own map symbols (github.com/nationalparkservice/symbol-library, BSD
licensed, forked from Mapbox's Maki) for the six categories it covers —
professional, purpose-built pictograms beat ad-hoc "fuel pump"/"picnic
table" line art. `forest` has no NPS equivalent and stays hand-drawn.
The glyph now sits in the pin's head rather than centered on a flat dot,
which needed real geometry (both layers anchor to the same point, so the
offset is the gap between where the pin's head-center ends up and where the
glyph's own visual center already sits) rather than the old anchor="center"
zero-offset placement.
A park4night/OsmAnd POI export (e.g. a p4n2gpx area export) tags every
waypoint with a category and a per-category color/icon in its <extensions>
block, all of which was previously thrown away — every waypoint rendered as
the same plain red dot, unreadable once a file has a few thousand of them.
Maptool::Gpx now captures category/color/icon (waypoint_style), matched by
namespace URI rather than local element name: a p4n2gpx file carries both
<osmand:icon> and <locus:icon> side by side, and REXML strips prefixes from
Element#name, so both report as just "icon" — matching on that alone was
silently picking the (useless) Locus drawable path instead of the OsmAnd
category key. Regression test added for this.
On the map: waypoints are colored by category (falling back to the plain
track color for anything uncategorized), a small hand-drawn icon set
(public/js/icons.js's POI_ICONS, rasterized to SDF sprites at runtime) draws
a glyph on top for the categories it covers, the points source is clustered
so a dense export collapses into count bubbles instead of a solid blob, and
a legend in the side panel lists whichever categories are currently visible.
Splitting each file's GeoJSON into a lines source and a points source
(rather than one mixed source with a geometry-type filter per layer) was
needed for clustering, since MapLibre's cluster support only understands a
source made entirely of points.
GPX tracks were silently failing to render for large real-world files:
point_extensions used REXML's "extensions//*" XPath, and the // descendant
axis costs low-single-digit milliseconds per call regardless of subtree
size. Run once per point, that's negligible on small files but ~30s on a
real 8000-point track — long enough to hit a proxy timeout in production,
so the file just never appeared with no error. Replaced with plain
recursive child traversal (~40x faster on the same file, confirmed
29.9s -> 3.16s); test_parsing_many_points_with_extensions_stays_fast
guards against reintroducing it.
Also adds support for <rte> routes (not just <trk> tracks and <wpt>
waypoints), sharing the track/route conversion logic via a new
line_feature helper. Routes get their own "route" kind and a dashed
ROUTE_ICON in the file tree so the type is visible at a glance.
_addLayers handed MapLibre a URL and let it fetch the GeoJSON
internally — a 422 (a file REXML/Fit can't parse) just meant the
layer never appeared, with nothing telling the user why. It now
fetches the file itself first, alerts with the actual error and
un-checks the box on failure.
TrackStats.build_profile now also computes elapsed_secs per point
(relative to the first known timestamp), alongside the existing
cumulative distance. Point x-positions stay distance-based either
way — only the shared axis strip's 5 tick labels (and the tooltip)
switch between the two, so toggling is a cheap re-render rather than
rebuilding the charts. The toggle only appears when a track actually
has elapsed-time data to switch to.
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.
Maptool::TrackStats computes these once, shared by Gpx and Fit so
both track feature shapes carry the same properties regardless of
source format. Hovering a track line (not clicking — these describe
the whole line, not one point) shows them in a popup, same mechanism
GPX waypoints already use.
Maptool::Fit reads Garmin's binary FIT format directly rather than
adding a gem — the one Ruby option depends on activesupport, unmaintained
since 2022, for a single-purpose binary parser. Only "record" messages
are read (position + altitude; everything else is skipped by byte
length, never interpreted); field numbers and scale/offset are
Garmin's own (fit-python-sdk's profile.py), and the framing plus all
extracted values were checked byte-for-byte against 5 real device
files from python-fitparse's test suite before this shipped.
A .zip upload (Garmin's bulk/FIT export format) is expanded into its
.gpx/.fit entries via rubyzip — that one's an actual dependency, since
ZIP's own format isn't the kind of narrow, single-purpose parsing FIT
above is.
MAPTOOL_ALLOWED_GITEA_USER now accepts a comma-separated list of
Gitea usernames instead of just one, for when more than one person
needs upload/delete/move access.
Upload/delete/move/create-folder now require logging in via Gitea
OAuth2 (only MAPTOOL_ALLOWED_GITEA_USER is granted write access);
reading stays public. Deploy secrets (session secret, OAuth2 client
credentials, allowed user) are written to .env from Gitea Actions
repo secrets on every deploy instead of living on the server by hand.
Also switch the container's bind address to "[::]" (dual-stack) so
the app is reachable over IPv6, not just IPv4.
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.
Uploading is now drag & drop (or click to browse) instead of a form;
folders can be created any time, not just during upload; files can be
dragged onto a folder to move them, or dropped elsewhere in the tree
to move back to the top level; files and folders can be deleted. Both
drag sources (an OS file drag and dragging an existing tree entry)
land on the same drop targets, told apart by a custom drag payload
type versus the browser's own "Files" type.
Also sort folders before files in the tree (previously interleaved
alphabetically).
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.
