This widget allows you to embed OpenStreetMap in a wiki page.

Using this widget

You can insert a map with the following wiki code: 

{{#widget:OpenStreetMap|lat=52.94762|lon=-1.1467897|zoom=16}}

Parameters

width
Width of the embedded map (default 400px).
height
Height of the embedded map (default 400px).
lat
The x-coordinate for the centre of the view.
lon
The y-coordinate for the centre of the view.
units
The type of map units used for the coordinates (defaults to 'degrees').
zoom
The zoom level (default 15).
showmarker
Adds a visual marker to the center of the map (default false).
showmouseposition
Displays the position of the mouse cursor in map coordinates.

Points of interest

poifile
Specifies the url of a file containing points of interest (POI) that should be overlaid on the map. See the file format description in [1]. Note: there is a bug that causes the last line of the poi file to be ignored; a workaround is to add a trailing line with a single '.' character.
poititle
The title of the POI layer (default 'Points of interest').

Storing points of interest on a wiki page

Instead of uploading a file you can add the points of interest to a wiki page and link to the raw page text, for example:

{{#widget:OpenStreetMap|...|poifile={{fullurl:Wiki page title|action=raw&templates=expand&ctype=text/plain}} }}

Note: If you change the contents of that wiki page you must purge the page cache (for each page that uses it in a map) before you can see the change.

Overlay a path

You can draw paths using connected line segments. This is useful for showing routes. Each path should have a unique name. For the parameters described below the placeholder '<id>' should be replaced with the name of the path.

path.<id>.title
Gives a title to the overlay (default "Route")
path.<id>.point.lat
Adds the latitude of a point to the path. You can specify this parameter many times to add all of the points to the path.
path.<id>.point.lon
Adds the longitude of a point to the path. You must specify this parameter the same number of times as the 'lat' parameter.
path.<id>.colour
Sets the colour to draw the path (default "#0033cc")
path.<id>.opacity
Sets the path opacity, in the range [0-1] (default 1)
path.<id>.width
Sets the line width (default 4)

Javascript alternatives

These alternatives can be used to cater for browsers that do not support javascript.

alt_image
The url of an image to represent the map.
alt_text
A description of the alt_image.
