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.
