Geohash

This module is a Geohash encoding and decoding implementation in pure Elm.

Functions

encode : Float -> Float -> Int -> String

Encodes coordinate (latitude, longitude precision) to geohash.

encode 57.648 10.41 6 == "u4pruy"

String

-> { lat : Float

, lon : Float

, latError : Float

, lonError : Float

}

Decodes geohash and returns center coordinate.

decodeCoordinate "u281zk" ==
{ lat = 48.14483642578125
, lon = 11.5740966796875
, latError = 0.00274658203125
, lonError = 0.0054931640625
}

String

-> { minLat : Float

, minLon : Float

, maxLat : Float

, maxLon : Float

}

Decodes a geohash and returns the bounding box.

decodeBoundingBox "u281zk" =
{ minLat = 48.14208984375
, minLon = 11.568603515625
, maxLat = 48.1475830078125
, maxLon = 11.57958984375
}
