The MapSources extension gives access to several data and mapping sources. It is of the Wikivoyage extensions.

インストール

• ダウンロードして、ファイルをextensions/フォルダー内のMapSourcesという名前のディレクトリ内に配置します。
• 以下のコードを LocalSettings.php の末尾に追加します:

  wfLoadExtension( 'MapSources' );
  

•  完了 – ウィキの「Special:Version」に移動して、拡張機能が正しくインストールされたことを確認します。

MediaWiki 1.26以前を稼働させている利用者へ:

上記の手順では、wfLoadExtension()を使用してこの拡張機能をインストールする新しい方法を記載しています。 この拡張機能をこれらの過去のバージョン (MediaWiki 1.26以前) にインストールする必要がある場合は、wfLoadExtension( 'MapSources' );の代わりに以下を使用する必要があります:

require_once "$IP/extensions/MapSources/MapSources.php";

カスタマイズ

The Map Sources special page uses project:map sources as a form of template for the Special:MapSources page output. This project page uses place holders as described below. The base name of this project page is taken from the mapsources message string (MediaWiki:Mapsources) of the content language.

• English wikis: Project:Map sources
• French wikis: Project:Sources de cartes
• German wikis: Project:Karten- und Datenquellen
• Italian wikis: Project:Fonte della mappa
• Polish wikis: Project:Mapy
• Japanese wikis : Project:地図情報源
• Chinese wikis : Project:地图来源
• and in Russia, Project:Источники карт maps you.

The text language will not be changed by the user language, it depends only on the content language. Therefore, you must have only one project page per wiki. If the project page does not exist, the extension will fail with an error:

エラー メッセージ:

• No project page Источники карт available

URL and search parameters

Two different types of input parameter sets are accepted:

• The Wikipedia Georeference code like
  • 51.5_N_0.125_W_scale:10000_region:UK

• A comma- or semicolon-separated list of latitude, langitude, and parameters. Latitude and langitude can be written in decimal or sexagesimal forms, ie deg[°] [min['] [sec['']]] [N|S|E|W]. The parameters must be separated by spaces or underscores. The parameter name and its value are separated by a colon “:” or an equal sign “=”. Example:
  • 51.5,-0.125,scale:10000 region=UK

パラメーター

scale:N

Sets the desired map scale as 1:N. This will override the default scale 1:100.000 or the type.

type:T

Sets the type of this location, which will be used for the reverse mapping of the points. Will also set the default map scale. Types are:

Type	Description	Scale
country	(e.g. "type:country")	1:10,000,000
state	Where applicable	1:3,000,000
adm1st	Administrative unit of country, 1st level (province, county)	1:1,000,000

landmark	Cultural landmark, building of special interest, tourist attraction and other points of interest.	1:10,000

dim:D

Specifies the size of a location by meters. Not yet supported.

region:R

Sets the preferred map region of coverage, used in selecting appropriate map resources for the area. The region should be supplied as either a two character ISO 3166-1 alpha-2 country code, or an ISO 3166-2 region code. Examples:

• US
• DE
• DE-BB (Brandenburg state in Germany)

globe:G

Specifies other worlds than earth. Such as Moon or other planets.

precision:P

Specifies the number of valid decimal places of the coordinate. Default value is 6.

Approximation of the Universal Transverse Mercator conversion

This program uses Redfearn’s formulae to convert a given latitude and longitude into the equivalent Transverse Mercator (TM) coordinates.

Meridian Distance

The Meridian Distance m from the equator is given approximately by:

${\begin{aligned}m&=r\left(\left(1-{\frac {e^{2}}{4}}-{\frac {3}{64}}e^{4}-{\frac {5}{256}}e^{6}\right)\varphi -\left({\frac {3}{8}}e^{2}+{\frac {3}{32}}e^{4}+{\frac {45}{1024}}e^{6}\right)\sin(2\varphi )\right.\\&+\left.\left({\frac {15}{256}}e^{4}+{\frac {45}{1024}}e^{6}\right)\sin(4\varphi )-\left({\frac {35}{3072}}e^{6}\right)\sin(6\varphi )\right)\end{aligned}}$

where are

• r - the size of the major semi axis
• e - the eccentricity of the reference ellipsoid
• φ - the latitude in radian

Calculation of Northing and Easting

使用法

dd2dms

• dd2dms converts degrees to degree-minute-second format. It uses the required coordinate and the optional plus, minus and precision values.
  • Application: {{#dd2dms: 14.5|plus=String for the positive cardinal direction|minus=String for the negative cardinal direction|precision=decimal places}}
  • Example: {{#dd2dms: 14.58|precision=4}} gives {{#dd2dms: 14.58|precision=4}}
  • Example: {{#dd2dms: 14.58|precision=2}} gives {{#dd2dms: 14.58|precision=2}}

Degree values can be both sexagesimal and decimal.

Strings for the cardial directions will be added to the dms value. They can be empty, single letters or strings and will be added at the end of the conversion result. If the original value is graeter or equal zero, the plus string is added, otherwise the minus string is used.

deg2dd

• deg2dd converts degrees to decimal-degree format.
  • Application: {{#deg2dd: 14° 23' 45''|precision=decimal places}}
  • Example: {{#deg2dd: 14° 23' 45'' S|precision=3}} gives {{#deg2dd: 14° 23' 45'' S|precision=3}}

Sexagesimal coordinate format

You can enter coordinates in the sexagesimal system in the following way:

deg[°] [min['] [sec['']]] [N|S|E|W]

deg, min, sec mean the degree, minute and second values, respectively. The designations can be omitted, but the succession must be kept.

There are alternative characters for the designations in the following way:

Meaning	Characters
Degree	°
Minute	' ‘ ’ ′
Second	" '' “ ”
Minus	- −
