geohash

Geohash library for clojure.

Usage

Include geohash with leiningen:

(defproject your-project "1.0.0-SNAPSHOT"
    :dependencies [[org.clojars.sunng/geohash "1.0.1"]])

Encode coordinate into geohash:

(use [geohash.core])
(encode 37.8324 112.5584 9)
"ww8p1r4t8"

Decode geohash into coordinate:

(decode "ww8p1r4t8")
{:lat 37.83238649368286,
 :lon 112.55838632583618,
 :lat-err 2.1457672119140625E-5,
 :lon-err 2.1457672119140625E-5}

Decode geohash into bound box:

(decode-bbox "ww8p1r4t8")
{:minlon 112.55836486816406,
 :maxlon 112.5584077835083,
 :minlat 37.83236503601074,
 :maxlat 37.83240795135498}

Tip: Filter by directory path e.g. /media app.js to search for public/media/app.js.
Tip: Use camelCasing e.g. ProjME to search for ProjectModifiedEvent.java.
Tip: Filter by extension type e.g. /repo .js to search for all .js files in the /repo directory.
Tip: Separate your search with spaces e.g. /ssh pom.xml to search for src/ssh/pom.xml.
Tip: Use ↑ and ↓ arrow keys to navigate and return to view the file.
Tip: You can also navigate files with Ctrl+j (next) and Ctrl+k (previous) and view the file with Ctrl+o.
Tip: You can also navigate files with Alt+j (next) and Alt+k (previous) and view the file with Alt+o.
