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

Installation

  • <translate> [[<tvar name=2>Special:ExtensionDistributor/MapSources/de-formal</tvar>|Download]] and move the extracted <tvar name=name>MapSources/de-formal</tvar> folder to your <tvar name=ext>extensions/</tvar> directory.</translate>
    <translate> Developers and code contributors should install the extension [[<tvar name=git>Special:MyLanguage/Download from Git</tvar>|from Git]] instead, using:</translate>cd extensions/
    git clone https://gerrit.wikimedia.org/r/mediawiki/extensions/MapSources%2Fde-formal
  • <translate> Add the following code at the bottom of your <tvar name=1>LocalSettings.php </tvar> file:</translate> 
    wfLoadExtension( 'MapSources/de-formal' );

Special page

Customization

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.

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:

Error messages:

  • 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

Parameters

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
adm2nd Administrative unit of country, 2nd level 1:300,000
city City, town or village, unspecified population. Will be treated as a minor city. 1:100,000

isle 1:100,000
waterbody Bays, fjords, lakes, glaciers, inland seas... 1:100,000
airport 1:30,000
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)

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:

<math>\begin{align} 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{align} </math>

where are

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

Usage

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 - −
