Geohash utilities

Description

Various common functions that arise when working often with geohashes

Usage

gh_delta(precision)

Arguments

Value

Length-2 numeric vector; the first element is the latitude (y-coordinate) half-width at the input precision, the second element is the longitude (x-coordinate).

Note

Caveat coder: not much is done in the way of consistency checking since this is a convenience function. So e.g. real-valued "precision"s will give results.
