Поле поиска на заглавной странице OpenStreetMap использует множество источников, чтобы найти список интересующих вас мест, из которых вы можете выбрать любое, чтобы увидеть его на карте.
Коротко говоря, вы можете начать искать:
- просто название какого-либо населенного пункта, улицы, или тип здания,
- улицу или тип здания, находящиеся рядом с каким-либо населенным пунктом (после запятой или слова 'near' ('рядом')), или
- почтовый индекс в Великобритании, США или Канаде.
(NB. Concerns have been raised about how 'free' the data used by Geo Names is. )
Geonames (geonames.org) is a wiki-style database of names of all kinds of feature, but particularly places, together with their locations and other information such as alternate languages, elevation, population and others from various sources.
When you enter just a name of a place (lake, mountain, river etc) in the search box you are likely to get one or more locations from Geonames in the results panel. However, bear in mind that these locations may not have been added to the OpenStreetMap, so viewing a Geonames-located place may just show a blank map; or it may have no detail.
Geonames is unlikely to locate individual streets for you.
postcode support in Geocoder.XX
When you search for a UK postcode, OpenStreetMap consults NPE/Free The Postcode, a database of geolocated postcodes contributed to by people who know both a postcode and its location. It is not very complete, but can find partial postcodes.
UK postcodes are one or two letters, followed by one or two numbers, and in London sometimes a further letter, a space (which can be omitted), and then a further digit and two letters. For example:
CB21 5DZ SW1A 0AA N4 7TJ
US ZIP Codes
When you search for a US ZIP code, OpenStreetMap consults Geocoder.us, which has a database of geolocated ZIP codes.
US Zip codes are either five digits, or five digits followed by a hypen and four more digits. For example:
When you search for a Canadian Postcode, OpenStreetMap consults Geocoder.CA, which has a database of geolocated postcodes.
Canadian postcodes are two letters separated by a digit, a space (which can be omitted), and then two digits separated by a letter. For example:
French Postcodes ( not supported)
The two first number of the postcode is the same in 99% of the number of administrative code department. So 59300 code is locate in administrative department of value 59. The postcode is produce by "La poste" who distribute letters . Many small town have the same postcode but big town have many.So the postcode is not efficient to locate the town ( administrative limitation). A service offer way to search postcode from town name
