Replaced the OSMUS Tile Service and OpenMapTiles with the official OpenHistoricalMap tile server and tile schema. Installed Timescope and maplibre-gl-dates for time filtering.

Then Now
Limon in 1962 Limon today
California State Route 152 through Pacheco Pass in 1935 California State Route 152 through Pacheco Pass today

This is still a proof of concept. No decision yet on whether to integrate this functionality into the main OSM Americana application or maintain it as a separate application specific to OHM. The design and tagging implications are being discussed in this forum thread.

Shortlist of to-do items:

Fixes #1283.

This implements the German Autobahn shield for #389. It’s OHM-specific for now because only OHM is consistently namespacing the network=* value with DE:. The corresponding routes in OSM are still tagged with an out-of-pattern network=BAB.

OHM is consistently tagging these roads based on their symbols instead of trying to map them to English keywords.

The community is compiling a list of more network=* values that they’ve used or intend to use soon.
