geocode#
- geocode(level=None, names=None, countries=None, states=None, counties=None, scope=None) NamesGeocoder#
Create a NamesGeocoder. Allow to refine ambiguous request with where() method, scope that limits area of geocoding or with parents.
- Parameters:
- level{‘country’, ‘state’, ‘county’, ‘city’}
The level of administrative division. Autodetection by default.
- nameslist or str
Names of objects to be geocoded. For ‘state’ level: ‘US-48’ returns continental part of United States (48 states) in a compact form.
- countrieslist
Parent countries. Should have same size as names. Can contain strings or Geocoder objects.
- stateslist
Parent states. Should have same size as names. Can contain strings or Geocoder objects.
- countieslist
Parent counties. Should have same size as names. Can contain strings or Geocoder objects.
- scopestr or Geocoder
Limits area of geocoding. If parent country is set then error will be generated. If type is a string - geoobject should have geocoded scope in parents. If type is a Geocoder - geoobject should have geocoded scope in parents. Scope should contain only one entry.
- Returns:
- NamesGeocoder
Geocoder object specification.
