The value of 'maps' can be, for example; [{:lat 1 :lng 4} {:lat 2 :lng 3}].
If you enter (min [{:lat 1 :lng 4} {:lat 2 :lng 3}]) in the repl the result will be {:lat 1 :lng 3} If you replace 'min' by its definition you get; (min [{:lat 1 :lng 4} {:lat 2 :lng 3}]) => (zipmap [:lat :lng] (map (fn [k] (apply clojure.core/min (map k [{:lat 1 :lng 4} {:lat 2 :lng 3}]))) [:lat :lng])) I hope this helps.
