Line or transfer details
All metro networks stay visible, including metros without a circle. Each result card is the largest circle that does not reuse another result's rail segments and focuses it on the map; clicking any visible line, platform, transfer, street, or station updates this final section directly.

Clock time vs solar time
Civil time gives a whole region one clock. Longitude determines mean solar time. Their difference shifts the Sun's highest point away from 12:00.
Solar noon displacement
Color is calculated continuously from each timezone's UTC offset and every point's longitude.
Local clock reading
Inspired by Stefano Maggiolo's map. Timekeeping boundaries since 1970 come from timezone-boundary-builder, using OpenStreetMap data under ODbL. Seasonal and historical offsets use pinned IANA 2026c rules; recurring daylight-saving changes are excluded from official-history eras.
Where water divides
Follow each river system to its final outlet. The Mississippi, Missouri, Ohio, and their tributaries form one primary watershed.

Receiving-body colors
Colors show the receiving sea or ocean. Smaller bays and estuaries use their larger receiving body’s color. Gray indicates unresolved drainage. Outlines mark individual basins and include coastlines.
Drainage details
From terrain to catchments
Catchments are joined by their final downstream outlet, removing internal tributary boundaries. Catchments sharing the same terminal node form one basin. Outside North America, branching rivers follow the modeled main stem; secondary outlets remain separate. Canals do not automatically combine all connected river systems. Documented underground connections join karst catchments to their downstream basin. Gray surface sinks have unverified final drainage; they are not confirmed endorheic basins. Rivers entering the Caspian Sea keep separate watersheds by river outlet and share the same receiving-body color. The marker shows the modeled drainage endpoint, not necessarily the deepest point of a lake.
Receiving bodies use generalized Natural Earth marine areas; colors do not change basin boundaries. North American boundaries use HydroSHEDS v2’s 1 arc-second grid (about 30 m); other regions use GRIT v1.0 catchments derived from 30 m terrain, with simplification in the source vectors. Zoom in for full detail. Source resolution is not positional accuracy: a boundary within 100 m of the true divide everywhere is not verified. Terrain shading is a separate visual reference.
Coverage spans North and South America, Europe, Africa, Asia, and Oceania. Greenland and Antarctica are not included. Composite coastal areas below the source stream threshold are left uncolored. Gray surface depressions without a supplied outlet have no outlet marker.

Zoning + current status
Each lot combines its tax class and building record with current zoning and historic-district boundaries.

Parcel details
This is an exploratory classification, not a legal zoning determination. Parcel records are from Jersey City's 2024 tax-map service; zoning and historic overlays are from the city's interactive zoning map. “Historic” means a mapped historic district or a recorded build year before 1946.
