Research Places, Routes, and Time Zones with Hermes

The bundled Maps skill can search place names, reverse-geocode coordinates, find nearby categories, estimate distance and travel time, request directions, identify time zones, and work with bounding boxes. It is useful for research and planning, not a replacement for safety-critical navigation.

Resolve the place first

A place name may be ambiguous. Confirm the returned display name, coordinates, country or region, and bounding box before using it as a route endpoint. For a location pin, keep latitude and longitude in the correct order and show the user the resolved area before acting on nearby results.

Nearby searches can use coordinates or an address-like --near value. Distance and directions support travel modes, but estimates depend on available map and routing data. A straight-line distance, driving route, and walking route answer different questions.

Mapping checklist

Resolve each origin and destination to the intended place.
Confirm coordinate order and hemisphere signs.
Name the travel mode and whether the result is an estimate.
Set a reasonable radius and result limit for nearby searches.
Check time-zone output for the coordinates, especially near borders.
Preserve a human-reviewable map link or place name with key results.

Common pitfalls

Selecting the first geocoding match. Repeated street or city names can point to another region.
Swapping latitude and longitude. The result may still be valid coordinates but an entirely different place.
Presenting route time as guaranteed. Traffic, closures, access rules, and provider freshness can change the trip.
Using a broad category without reviewing results. Tags and business classifications vary.
Treating a time zone as a fixed UTC offset. Daylight-saving rules can change the offset by date.

Verification

Reverse-geocode important coordinates, compare the display name with the requested place, and sanity-check route distance and direction. For nearby results, inspect at least the top candidates' names and coordinates rather than returning an unreviewed list. For time-sensitive travel, confirm with a current navigation source before departure.
