Unrelated to anything the app renders, but the doc already collects
NPS-ecosystem color facts and this came up while sourcing colors
for a 3D print of the shield.
Offline tiles were built from Protomaps' own basemap schema, needing a
completely separate hand-tuned theme (protomaps-themes-base + OFFLINE_THEME)
from the online Liberty style's ONLINE_STYLE_PATCH — the two could never be
made to match exactly no matter how much either side got tuned (today's
session found and fixed several mismatches: building opacity, park
boundaries, road casings, road widths).
Offline.pmtiles is now built with Planetiler's default OpenMapTiles profile
against Geofabrik per-country OSM extracts (osmium-merged when more than one
country is selected), the same vector schema Liberty already expects.
offlineStyle() now clones the same Liberty JSON (vendored as a local
snapshot for reliability with no internet) and applies the identical
ONLINE_STYLE_PATCH, just repointed at local PMTiles/glyphs/sprite — one
palette instead of two, correct on both sides by construction.
Also vendors Liberty's icon sprite for the first time (offline had none
before), adds Java/osmium-tool/planetiler.jar to the Docker image, and
removes the now-unused protomaps-themes-base dependency and the
theme-comparison debug page that found today's bugs.
Self-hosted Bold woff2 only (the one weight .topbar__brand renders at)
under public/vendor/national-park-typeface/ — a router-carved-signage
display face for the "MAPTOOL" heading, matching the uppercase/
letter-spaced treatment it already had. Everything else stays on the
system font stack; this is a wordmark swap, not a body-text one.
docs/nps-resources.adoc/third-party-notices.adoc updated to record it.
- national-park-service/fonts: unofficial but genuinely open (SIL OFL
1.1) typefaces inspired by public-lands signage -- unlike the
proprietary Rawlinson/Frutiger this app already ruled out, this one
has no licensing blocker if the look is ever wanted in this app's
own UI chrome.
- The official NPS Data API (developer.nps.gov) -- a legitimate
government data source, separate from the Mapbox-Atlas-licensed
tile service. No current use case (this app isn't NPS-park-specific)
but worth remembering.
- Two hobby projects (carlknutson/nps-changes-site,
seankelliher/us-national-parks-alerts) noted as real-world examples
of consuming that API, not as reusable libraries.
ONLINE_STYLE_PATCH mirrors OFFLINE_THEME's color choices onto
OpenFreeMap Liberty's OpenMapTiles layer ids (a separate hand-built
table -- the two schemas share no layer names). loadOnlineStyle
fetches Liberty's style.json once, patches it in place, and the
result replaces the plain URL everywhere ONLINE_STYLE is used --
MapLibre accepts a style object anywhere it accepts a style URL, so
applyStyle needed no change.
Runs before the map (and the rest of the page) is constructed, so
there's no flash of Liberty's own colors first -- but with a 3s
timeout and a catch-all fallback to the plain URL, since this app is
meant to keep working offline in the field and blocking startup on a
remote style server would undermine that.
Verified in a real browser: online map now visually matches the
offline theme (cream ground, brown/khaki land cover, green parks,
muted roads), no console errors, Online/Offline toggle still works.
Home now fitBounds()s a country-wide bbox instead of resetting to
CENTER/ZOOM's Bratislava point, since Home resetting into the same
city you'd already be looking at wasn't useful.
The overview map is NPS's own overview plugin (npmap5-plugins, still
on an unmerged branch), vendored and converted from its UMD dist
build to a plain ES module. Patched one MapLibre API break found while
verifying it: the plugin reads map.transform (public in the MapLibre
~2.4 it targets) to relax the inset's polar pan limit; MapLibre 6 (this
app's vendored version) no longer exposes .transform at all, so it
threw on load. Guarded to skip that cosmetic adjustment when absent
instead.
NPMap4 has infoboxControl: a generic "click anything, show every raw
property" debug view, kept separate from a dataset's own curated popup.
Not portable code (Leaflet), but the concept is: Alt+click anywhere now
opens a popup listing every rendered feature at that point via
map.queryRenderedFeatures — base map OSM tags included, not just this
app's own GPX/FIT/radar layers — with a raw key/value table per feature.
No dedicated UI for it on purpose: a keyboard-modified click needs no
button, toggle state, or cursor change of its own, and it's fine for it to
coexist with a layer's own click handler firing on the same click (e.g. a
GPX waypoint's normal popup) since this is a power-user/debugging
affordance, not a replacement for those. Feature properties can come from
an uploaded GPX/FIT file (untrusted input) via this app's own layers, so
every value is escaped the same way gpx.js's popups already are.
A CLI tool for pulling ArcGIS/ESRI REST data into GeoJSON/GeoPackage -
different category from the browser plugins/icons elsewhere in this doc.
No current use case (we have no ArcGIS data source to query) and,
unlike everything else surveyed so far, no LICENSE file at all.
v4 is one mature, accumulated framework; npmap5 is a still-in-progress
rewrite split into small, independently-versioned (mostly pre-1.0)
plugins, several of which aren't merged yet. Worth knowing so we don't
assume v5 already has everything v4 does.
Noted for completeness in docs/nps-resources.adoc — both proprietary/
licensed fonts, unlike the SIL OFL Noto Sans already vendored, so not
adoptable. The editorial style guide is NPS's own writing/terminology
conventions, not a design or code resource, included only since it was
shared alongside the typography notes.
A reference doc (docs/nps-resources.adoc) covering everything looked at
while pulling icons/controls/theme colors from NPS's mapping ecosystem:
what's actually in use (symbol-library, home-button, the Park Tiles-inspired
offline palette), what was considered and deliberately skipped (svg-icons,
markdown-handlebars, the unmerged overview/carto/wms branches) and why, the
Park Tiles cartography research (Harpers Ferry Center lineage, the four
style variants, why the actual tile service is off-limits via Mapbox
Atlas licensing, the public style JSON and Mapbox Studio style IDs found),
and the still-open upstream PR revising artwork for three icons we use.
Worth having as a knowledge base rather than re-deriving any of this from
scratch next time — NPS's tooling has repeatedly turned out to be a better
source than building something from nothing.
