Location

Get location data, geocoding, coordinates, and maps.

Geocoding (Address → Coordinates)

Nominatim (OpenStreetMap - Free)

# Search address
curl -s "https://nominatim.openstreetmap.org/search?q=1600+Pennsylvania+Avenue,Washington+DC&format=json" | jq '.[0] | {lat, lon, display_name}'

# With limit
curl -s "https://nominatim.openstreetmap.org/search?q=Paris,France&format=json&limit=1" | jq '.[0]'

# Reverse geocoding (coordinates → address)
curl -s "https://nominatim.openstreetmap.org/reverse?lat=48.8584&lon=2.2945&format=json" | jq '.display_name'

Google Geocoding API

# Setup
export GOOGLE_MAPS_KEY="xxx"

# Geocode address
curl -s "https://maps.googleapis.com/maps/api/geocode/json?address=1600+Pennsylvania+Avenue,Washington+DC&key=$GOOGLE_MAPS_KEY" | jq '.results[0].geometry.location'

# Reverse geocode
curl -s "https://maps.googleapis.com/maps/api/geocode/json?latlng=48.8584,2.2945&key=$GOOGLE_MAPS_KEY" | jq '.results[0].formatted_address'

IP Geolocation

# Get location from IP (ip-api.com - free)
curl -s "http://ip-api.com/json/" | jq '{country, city, lat, lon, timezone, isp}'

# Specific IP
curl -s "http://ip-api.com/json/8.8.8.8" | jq '.'

# ipinfo.io

Distance Calculation

# Haversine formula (great-circle distance)
python3 -c "
from math import radians, sin, cos, sqrt, atan2

def haversine(lat1, lon1, lat2, lon2):
    R = 6371  # Earth radius in km
    dlat = radians(lat2 - lat1)
    dlon = radians(lon2 - lon1)
    a = sin(dlat/2)**2 + cos(radians(lat1)) * cos(radians(lat2)) * sin(dlon/2)**2
    c = 2 * atan2(sqrt(a), sqrt(1-a))
    return R * c

# New York to Los Angeles
distance = haversine(40.7128, -74.0060, 34.0522, -118.2437)
print(f'{distance:.1f} km')

Address Validation

# Validate and normalize address
curl -s "https://address-validation.googleapis.com/v1:validateAddress?key=$GOOGLE_MAPS_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "address": {
      "regionCode": "US",
      "addressLines": ["1600 Pennsylvania Avenue", "Washington DC"]
    }
  }' | jq '.result.geocode.location'

Tips

• Nominatim: Free but rate limited (1 req/sec)
• Google Maps: Requires API key, paid after free tier
• Use Accept-Language header for localized results
• Cache geocoding results to save API calls
• Handle cases where geocoding fails
