Calculates a geohash value given two
fields representing latitude and longitude.
| Parameter | Type | Required | Default | Description |
|---|---|---|---|---|
as | string | false | _geohash | The name of the field that is produced by the function. |
lat | string | false | ip.lat | The field to use for latitude. |
lon | string | false | ip.lon | The field to use for longitude. |
precision | number | false | 12 | The precision to use in the calculation. Usually 12 is enough. |
Examples
Calculate the geohash value of a
set of coordinates.
logscale
geohash(lat=myLatField, lon=myLonField)
This example computes the geohash
for Greenwich:
logscale
lat:=51.477928 | lon:=0.0 | g:=geohash(lat=lat, lon=lon)
The result is gcpuzgrbxvrc.
