使用Nominatim进行openstreetmap地址搜索/解析

Nominatim（来自拉丁语，意思是“名称”）是一个可以按名称和地址来搜索OSM中的数据，并生成OSM点的合成地址的工具（反向地理编码）。可用在http://nominatim.openstreetmap.org找到这个工具。Nominatim也用在OpenStreetMap首页的搜索工具栏中，同时也为MapQuest Open Initiative提供搜索支持。

本页面提供了使用说明。要了解关于Nominatim如何工作的细节请查看发展概况以及这个FAQ。这里还有一个关于各个国家的语言代码和各个国家地址格式的列表。

搜索

Nominatim为OSM的数据集中已命名（或编号）的内容，以及其他无名的功能子集（酒吧，旅馆，教堂等）进行了索引。

搜索首先会从左至右进行，如果失败的话会再从右到左搜索。

这两个搜索都会得到结果：皮尔金顿大道，伯明翰 伯明翰，皮尔金顿大道

（逗号是可选的，但加上逗号可以降低搜索的复杂程度并提高搜索精度。）

门牌号码已经被定义了的区域，可以使用：135皮尔金顿大道，伯明翰

特殊的关键词

在搜索中不同的关键字会被翻译成特定OSM标签（例如，酒吧=>市容=酒馆）。这里有一个这样特殊短语的列表。

参数

 http://nominatim.openstreetmap.org/search?<params>
 http://nominatim.openstreetmap.org/search/<query>?<params>

 format=[html|xml|json|jsonv2]
   Output format

 json_callback=<string>
   Wrap json output in a callback function (JSONP) i.e. <string>(<json>) 

 accept-language=<browser language string>
   Preferred language order for showing search results, overrides the browser value.  
   Either uses standard rfc2616 accept-language string or 
   a simple comma separated list of language codes.

 q=<query>
   Query string to search for.  Alternatively can be entered as:

 street=<housenumber> <streetname>
 city=<city>
 county=<county>
 state=<state>
 country=<country>
 postalcode=<postalcode>
   (experimental) Alternative query string format for structured requests. 
   Structured requests are faster and require less server resources. 
   DO NOT COMBINE WITH q=<query> PARAMETER.

 countrycodes=<countrycode>[,<countrycode>][,<countrycode>]...
   Limit search results to a specific country (or a list of countries).  
   <countrycode> should be the ISO 3166-1alpha2 code, 
   e.g. gb for the United Kingdom, de for Germany, etc.

 viewbox=<left>,<top>,<right>,<bottom>
 or viewboxlbrt=<left>,<bottom>,<right>,<top>
   The preferred area to find search results

 bounded=[0|1]
   Restrict the results to only items contained with the bounding box. 
   Restricting the results to the bounding box also enables searching by amenity only. 
   For example a search query of just "[pub]" would normally be rejected
   but with bounded=1 will result in a list of items matching within the bounding box.

 polygon=[0|1]
   Output polygon outlines for items found 
   (deprecated, use one of the polygon_* parameters instead)

 addressdetails=[0|1]
   Include a breakdown of the address into elements

 email=<valid email address>
   If you are making large numbers of request please include a valid email address
   or alternatively include your email address as part of the User-Agent string.
   This information will be kept confidential and only used to contact you in the
   event of a problem, see Usage Policy for more details.

 exclude_place_ids=<place_id,[place_id],[place_id]>
   If you do not want certain openstreetmap objects to appear in the search result, 
   give a comma separated list of the place_id's you want to skip.

 limit=<integer>
   Limit the number of returned results.

 dedupe=[0|1]
   No explanation yet.

 debug=[0|1]
   No explanation yet.

 polygon_geojson=1
   Output geometry of results in geojson format.

 polygon_kml=1
   Output geometry of results in kml format.

 polygon_svg=1
   Output geometry of results in svg format.

 polygon_text=1
   Output geometry of results as a WKT.

反向地理编码/地址查询

反向地理编码由纬度和经度产生一个地址。可选的缩放参数指定用于显示某信息在openlayers上显示的合适的缩放级别。
