javascript - 在开放街道 map 中进行提名搜索

Question

我需要提名搜索方面的帮助。我需要获得特定城市最近的学校、银行、杂货店等。我在 http://wiki.openstreetmap.org/wiki/Nominatim/Special_Phrases/EN 中找到了关键词, 但我不知道它怎么用，我试着给 http://nominatim.openstreetmap.org/search?q=grocery,bangalore&format=xml&polygon=1&addressdetails=1 , 但对于某些关键字没有结果。谁能帮帮我..？

Answer 1

检查他们的 wiki entry

Why wasn't anything found for my search

There are a number of reasons why no result may have been found:

1. There is no data currently in OSM which matches your criteria. Data which you expect to match may be defective in some way. For example, if you search for "Springfield, Massachusetts", it may not be found if the state border has been damaged and no longer encloses Springfield.
2. The data has not yet been indexed, nominatim is normally a minimum of 2 days behind.
3. There are significant differences in the spaces (i.e. placestrasse & place strasse)
4. The search query is out of order (i.e. City, Street, Country) (Note: this seems to be a common German search query which currently doesn't work)
5. The search query does not use the correct encoding

原因好像是没有符合你条件的数据

更新

特殊短语的使用方式如下。

为了找到印度的所有机场，

http://nominatim.openstreetmap.org/search?q=airports%20in%20india&format=xml

结果是

同样，如果我想知道德里附近的机场(类加罗尔附近的机场没有数据)，

http://nominatim.openstreetmap.org/search?q=airports%20near%20delhi&format=xml

您可以附加 &polygon=1 以获取多边形点，附加 &addressdetail=1 以获取上述每个查询的基于地址的 xml。
