GeoIP

The catalog has a set of APIs for guessing at your geographical location based on your current IP address.

You can access these with the ark-catalog-geoip-tool tool.

For example:

~/ark$ ./build/ark-catalog-geoip-tool
{
  "accuracy_radius_m": 5000.0,
  "city": "Monroeville",
  "country": "United States",
  "ip_address": "172.32.10.10",
  "latitude": 40.485,
  "longitude": -79.918,
  "subdivisions": [
    "Pennsylvania"
  ],
  "time_zone": "America/New_York"
}

This information is very coarse and generally only useful for allowing robots to determine their time zone.
