查询返回一个包含一个或多个 OneMapResultItems

>>> geo = OM.geocode("%s,%s" % (res[0]['x'], res[0]['y']))
>>> type(geo)
<class 'core.ext.onemap.OneMapResult'>
>>>
>>> geo

$ pip install onemap

SVY21

OneMapAPI以SVY21格式返回坐标（而不是 更常见的WGS84 lat，液化天然气格式）

可以调用OneMap API在这两者之间进行转换 投影系统（还没有被这个库包装）

但是，如果你想在不命中的情况下转换点 一个外部API，看看这个很棒的opensource库

一个很棒的svy21库的python版本的副本 包括在这个回购协议中，但所有的信贷自然都归团队所有。
