The GeoData extension allows articles to specify their geographical coordinates and publishes these coordinates via the HTTP API .
Установка
Search backends
Прежде всего, решите, какой сервер поиска использовать:
- MySQL (по умолчанию): подходит для небольших и средних установок. Не требуется никаких настроек. It does not use MySQL's built-in spatial indexes because when the extension was being developed, SPATIAL was supported only by MyISAM storage engine, which is worse than nothing. Instead, it uses 0.1x0.1 degree tiles for search, which results in a slightly higher I/O, but faster updates.
- ElasticSearch — мощная поисковая система. When using ElasticSearch as a backend, GeoData works as a plugin for CirrusSearch which adds ES text search to the wiki.
Процесс
- Скачайте и распакуйте файл(ы) в папку с названием
GeoData
в вашей папкеextensions/
.
Вместо этого разработчикам и соавторам кода следует установить расширение из Git, используя:cd extensions/
git clone https://gerrit.wikimedia.org/r/mediawiki/extensions/GeoData - Добавьте следующий код в конце вашего файла LocalSettings.php :
wfLoadExtension( 'GeoData' );
- Выполните скрипт обновления, который автоматически создаст необходимые таблицы, используемые расширением.
- If you're about to use GeoData with ElasticSearch, install CirrusSearch then add to LocalSettings.php, below the GeoData loading.
$wgGeoDataBackend = 'elastic';
- Готово – Перейдите на страницу Special:Version на своей вики, чтобы удостовериться в том, что расширение успешно установлено.
Использование
This extension adds a new parser function , {{#coordinates:}}
, that saves coordinates to the database. Function's input format is made as compatible as possible with GeoHack.
Глоссарий
- Coordinates - see w:geographical coordinates
- Globe - terrestrial body on which the coordinate resides. By default, Earth is assumed. Internally, globe is represented as lowercase strings. The following globes are supported:
earth
,mercury
,venus
,moon
,mars
,phobos
,deimos
,ganymede
,callisto
,io
,europa
,mimas
,enceladus
,tethys
,dione
,rhea
,titan
,hyperion
,iapetus
,phoebe
,miranda
,ariel
,umbriel
,titania
,oberon
,triton
andpluto
. Globes not mentioned in this list will be assumed to have generic characteristics: longitude range 0-360°, Eastern longitude is positive. Longitude sign for known globes is taken according to IAU's conventions. - dim - approximate size of an object. Used by GeoData to restrict search and by GeoHack for determining appropriate map zoom. The default unit of measurement is metres, although the km suffix may be appended to indicate kilometres.
- Primary vs. secondary coordinates: primary coordinates define article subject's location, while secondary coordinates are other coordinates mentioned in the article. There can be only one primary coordinate per article, but as many secondaries as you like barring technical restrictions.
Функция парсера
Function format:
{{#coordinates:latitude|longitude|[primary|][GeoHack parameters|][extra parameters]}}
||
or | |
) are always ignored.- latitude and longitude can be specified in several formats:
- Direct signed input in degrees, e.g.
37.786971|-122.399677
, which corresponds to 37° 47′ 13.1″ N, 122° 23′ 58.84″ W.- As formatted number in the content language. Use
{{formatnum:}}
, to format a number of a expression.
- As formatted number in the content language. Use
- Degrees/minutes or degrees/minutes/seconds, e.g.
37|47.2183|-122|23.9807
or37|47|13.1|-122|23|58.84
. - Either of the above, but with sign specified by N/E/S/W letters:
37.786971|N|122.399677|W
37|47.2183|N|122|23.9807|W
37|47|13.1|N|-122|23|58.84|W
- Direct signed input in degrees, e.g.
- primary keyword specifies that these coordinates are primary (see #Glossary).
- Extra parameters are any combination of the following named parameters:
- dim: approximate size of the object.
- scale: Scale of map display for this object, e.g. scale of 300 is 1:300. Gets converted into dim internally using formula dim = scale / 10. If both scale and dim are set, dim has precedence.
- globe, see #Glossary.
- name: name of this point, up to 255 bytes (UTF-8).
- region: ISO 3166-1 alpha-2 country code (e.g. US or RU) or an ISO 3166-2 region code (e.g. US-FL or RU-MOS). This parameter is always capitalised internally.
- type: type of object with these coordinates, can be one of the following: country, satellite, state, adm1st, adm2nd, adm3rd, city, isle, mountain, river, waterbody, event, forest, glacier, airport, railwaystation, edu, pass, camera, landmark.
тип | Описание | Dim |
---|---|---|
country | (e.g. "type:country") | 1,000,000 |
satellite | geo-stationary satellites | 1,000,000 |
adm1st | Administrative unit of country, 1st level (province, state), e.g. U.S. states | 1,000,000 |
adm2nd | Administrative unit of country, 2nd level, e.g. US county | 30,000 |
adm3rd | Administrative unit of country, 3rd level | 10,000 |
city(pop) | cities, towns, villages, hamlets, suburbs, subdivisions, neighborhoods, and other human settlements (including unincorporated and/or abandoned ones) with known population (optional population in braces is ignored) |
10,000 |
airport | airports and airbases | 3,000 |
mountain | peaks, mountain ranges, hills, submerged reefs, and seamounts | 10,000 |
isle | islands and isles | 10,000 |
waterbody | bays, fjords, lakes, reservoirs, ponds, lochs, loughs, meres, lagoons, estuaries, inland seas, and waterfalls | 10,000 |
forest | forests and woodlands | 5,000 |
river | rivers, canals, creeks, brooks, and streams, including intermittent ones | 10,000 |
glacier | glaciers and icecaps | 5,000 |
event | one-time or regular events and incidents that occurred at a specific location, including battles, earthquakes, festivals, and shipwrecks | 5,000 |
edu | schools, colleges, and universities | 1,000 |
pass | mountain passes | 1,000 |
railwaystation | stations, stops, and maintenance areas of railways and trains, including railroad, metro, rapid transit, underground, subway, elevated railway, etc. | 1,000 |
landmark | buildings (including churches, factories, museums, theatres, and power plants but excluding schools and railway stations), caves, cemeteries, cultural landmarks, geologic faults, headlands, intersections, mines, ranches, roads, structures (including antennas, bridges, castles, dams, lighthouses, monuments, and stadiums), tourist attractions, valleys, and other points of interest | 1,000 |
Default dim: if no type is used or the type is unknown to this extension | 1,000 |
- GeoHack parameters: one or more pairs in format parameter:value, delimited by underscores (_) or spaces (e.g.
dim:1000_type:city
). No spaces are allowed between parameter and colon or between colon and value. The parameters are the same as extra parameters above. If a parameter exists in both GeoHack parameters and extra parameters, extra parameters always have precedence. This input is needed only for compatibility with preexisting {{coord}} templates - if your wiki is only designing a geographical coordinates template, it is best if you not used raw GeoHack parameters at all.

Условия для ошибки
GeoData checks the data it receives for a number of error conditions.
The following conditions result in coordinates being outright rejected and added to tracking category (the name of it is defined by MediaWiki:Geodata-broken-tags-category):
- Coordinates out of range:
{{#coordinates:56|04|N|190|00|E}} {{#coordinates:76|61|03|N|37|25|30|W}}
- Mixing coordinate signs and hemisphere letters:
{{#coordinates:primary|-26|04|N|178|46|E}} {{#coordinates:primary|26.16|N|-178.76|E}}
- More than one primary coordinate on page:
{{#coordinates:primary|26|04|N|178|46|E}}{{#coordinates:primary|26|04|N|178|46|E}}
- Too many coordinates on page: by default 500, 2000 on WMF.
The following errors are non-fatal by default:
- Unrecognised coordinate type:
{{#coordinates:primary|26|04|N|178|46|E|type=New York}} {{#coordinates:primary|26|04|N|178|46|E|type:village}}
API
GeoData has two API modules that perform search around a given point and coordinates for a given article(s).
list=geosearch
Searches for articles around the given point (determined either by coordinates, bounding box, or by article name).
Parameters:
- gscoord
- Coordinate around which to search: two floating-point values separated by pipe (|)
- gsradius
- Search radius in meters (10-10000). This parameter is required with the use of gscoord.
- gsbbox
- Bounding box to search in: pipe (|) separated coordinates of the corners in top|left|bottom|right order.
- gspage
- Title of page around which to search
- gsmaxdim
- Restrict search to objects no larger than this, in meters
- gslimit
- Maximum number of pages to return. No more than 500 (5000 for bots) allowed. Default: 10.
- gsglobe
- Globe to search on (by default
earth
). - gsnamespace
- Namespace(s) to search. Default: main namespace.
- gsprop
- What additional coordinate properties to return. Values (separate with '|'): type, name, country, region.
- gsprimary
- Whether to return only primary coordinates (
primary
), secondary (secondary
) or both (all
). Default:primary
.
Example:
- Search around the point with coordinates 37° 47′ 13.1″ N, 122° 23′ 58.84″ W:

GeoData extends two core API modules, list=allpages
and list=categorymembers
. The extended modules are called geopages
and geopagesincategory
. It adds two mutually exclusive parameters, withcoordinates
and withoutcoordinates
.
Конфигурация
Настройка | Тип | По умолчанию | Что такое |
---|---|---|---|
$wgMaxGeoSearchRadius |
int | 10000 | Maximum radius for geospatial searches, in meters. Reducing this value reduces server load |
$wgMaxCoordinatesPerPage |
int | 500 | Maximum number of coordinates per page, -1 means no limit |
$wgTypeToDim |
array | Long array, see the sources | Conversion table type --> dim |
$wgDefaultDim |
array | 1000 | Default value of dim if it is unknown |
$wgGlobes |
array | Long array, see the sources | Defines parameters of every globe |
$wgGeoDataWarningLevel |
array | array(
'unknown type' => 'none',
'unknown globe' => 'none',
'invalid region' => 'none',
)
|
Controls what GeoData should do when it encounters some problem. Reaction type:
|
$wgGeoDataIndexGranularity |
int | 10 | How many integer units per degree to use with database-only search. Influences performance. Run updateIndexGranularity.php after changing this setting. |
$wgGeoDataBackend |
string | 'db' | Which backend should be used by spatial searches: 'db' or 'elastic'. Note if you're planning to change it, do so before creating the database tables. |
