A Clojure library for computing geohashes.
You are responsible for acquiring DJIA data, but this library will at least tell you which date to acquire it for.
- Fully 30W-compliant
- Negative-zero compliant
- Avoids the scientific notation bug
Add as a Leiningen dependency:
[org.timmc/geohash "1.0.0"]Compute a geohash:
(require '[org.timmc.geohash :as gh])
;;= nil
(gh/dow-date 42.37 -0.5 (org.joda.time.LocalDate. 2012 3 5))
;;= #<LocalDate 2012-03-04> ;; different from input due to 30W rule
(slurp (java.net.URI. "http://geo.crox.net/djia/2012/03/04"))
;;= "12980.75"
(gh/geohash 42.37 -0.5 (org.joda.time.LocalDate. 2012 3 5) "12980.75")
;;= [42.71583060829183 -0.17616573365392707]See the org.timmc.geohash namespace documentation for more information:
(-> (the-ns 'org.timmc.geohash) meta :doc println)Built with Leiningen 2.x, although 1.x should work as well.
