To batch geocode, simply pass an array of addresses or coordinates instead of a single string
geocoder.geocode([
'1109 N Highland St, Arlington VA',
'525 University Ave, Toronto, ON, Canada',
'4410 S Highway 17 92, Casselberry FL',
'15000 NE 24th Street, Redmond WA',
'17015 Walnut Grove Drive, Morgan Hill CA'
])
.then(response => { ... })
.catch(err => { ... });
geocoder.reverse([
'35.9746000,-77.9658000',
'32.8793700,-96.6303900',
'33.8337100,-117.8362320',
'35.4171240,-80.6784760'
])
.then(response => { ... })
.catch(err => { ... });
// Optionally supply a custom key that will be returned along with results
geocoder.geocode({
'MyId1': '1109 N Highland St, Arlington VA',
'MyId2': '525 University Ave, Toronto, ON, Canada',
'MyId3': '4410 S Highway 17 92, Casselberry FL',
'MyId4': '15000 NE 24th Street, Redmond WA',
'MyId5': '17015 Walnut Grove Drive, Morgan Hill CA'
})
.then(response => { ... })
.catch(err => { ... });
Geocodio allows you to append additional data points such as congressional districts, census codes, timezone, ACS survey results and much much more.
To request additional fields, simply supply them as an array as the second parameter
geocoder.geocode(
[
'1109 N Highland St, Arlington VA',
'525 University Ave, Toronto, ON, Canada'
],
[ 'cd', 'timezone' ]
)
.then(response => { ... })
.catch(err => { ... });
geocoder.reverse('38.9002898,-76.9990361', ['census2010'])
.then(response => { ... })
.catch(err => { ... });
For forward geocoding requests it is possible to supply individual address components instead of a full address string. This works for both single and batch geocoding requests.
geocoder.geocode({
street: '1109 N Highland St',
city: 'Arlington',
state: 'VA',
postal_code: '22201'
})
.then(response => { ... })
.catch(err => { ... });
geocoder.geocode([
{
street: '1109 N Highland St',
city: 'Arlington',
state: 'VA'
},
{
street: '525 University Ave',
city: 'Toronto',
state: 'ON',
country: 'Canada',
},
])
.then(response => { ... })
.catch(err => { ... });
Optionally limit the number of maximum geocoding results by using the third parameter on geocode(...)
or reverse(...)
// Only get the frst result
geocoder.geocode('1109 N Highland St, Arlington, VA', [], 1)
.then(response => { ... })
.catch(err => { ... });
// Return up to 5 geocoding results
geocoder.reverse('38.9002898,-76.9990361', ['timezone'], 5)
.then(response => { ... })
.catch(err => { ... });
