Maps

Free distance/routing (OSRM) and geocoding (Nominatim/OSM). No API keys needed.

Geocoding (place name → coordinates)

bash scripts/geocode.sh "Times Square, New York"

Returns lat,lon and display name. Use this first when you have place names instead of coordinates.

Distance & Route

bash scripts/distance.sh <origin_lat>,<origin_lon> <dest_lat>,<dest_lon> [mode]

Modes: driving (default), foot, bicycle

Examples:

# Manhattan to JFK Airport
bash scripts/distance.sh 40.7580,-73.9855 40.6413,-73.7781 driving

# Golden Gate Park to Fisherman's Wharf (walking)
bash scripts/distance.sh 37.7694,-122.4862 37.8080,-122.4177 foot

Workflow

• If user gives place names → geocode both with geocode.sh
• Use returned lat,lon pairs with distance.sh
• Report distance in km and duration in minutes

Limits

• OSRM: free public demo server, no hard rate limit but be reasonable
• Nominatim: max 1 request/second (OSM policy), include User-Agent
• No live traffic data — durations are estimates based on road type/speed
• Routing is road-network only (no public transit)
