R: compute geohash from (average) coordinates

st_geohash {lwgeom} | R Documentation

## compute geohash from (average) coordinates

### Description

compute geohash from (average) coordinates

### Usage

    st_geohash(x, precision = 0)

### Arguments

`x` | object of class `sf`, `sfc` or `sfg`
`precision` | integer; precision (length) of geohash returned. From the liblwgeom source: “where the precision is non-positive, a precision based on the bounds of the feature. Big features have loose precision. Small features have tight precision.”

### Details

see http://geohash.org/ or https://en.wikipedia.org/wiki/Geohash.

### Value

character vector with geohashes

### Examples

    library(sf)
    lwgeom::st_geohash(st_sfc(st_point(c(1.5,3.5)), st_point(c(0,90))), 2)
    lwgeom::st_geohash(st_sfc(st_point(c(1.5,3.5)), st_point(c(0,90))), 10)
