Template:Map

Template documentation[view] [edit] [history] [purge]

Embeds an interactive map on a page, provided the gadget MediaWiki:Gadget-maps.js is enabled. This gadget visualizes OpenStreetMap data using a variant of the OpenStreetMap Americana map style in a MapLibre GL JS map. On the AARoads wiki, this supersedes the Kartographer extension, and there is no implementation of that extension on this wiki.

Uses

This template is intended to show points as well as linear features on a map, including (but not limited to):

• Roads
• Rivers
• Subway or train lines
• Ship courses
• Flight paths
• Explorers journeys

and more... This template can also be used to display point features on a map, i.e. coordinates.

Parameters

For overall display

width

Width, in pixels, of the map frame. full fits available space.

height

Height, in pixels, of the map frame.

navigation-position

Corner in which the navigation controls appear, or none to hide the navigation controls.

attribution-position

Corner in which the attribution control appears.

zoom

Zoom level of the map, from 1 to 19 (larger numbers zoom in further); default is automatically determined by the map, unless the only feature is a single point.

lat

Optional - initial coordinate of the center latitude of the map.

lon

Optional - initial coordinate of the center longitude of the map.

bearing

Initial bearing in degrees counterclockwise from north.

pitch

Initial pitch in degrees away from the plane of the screen.

plain

If anything other than yes (which is default), shows a surrounding frame with a caption (without this parameter, text parameter will be ignored).

align

Alignment with respect to the page if map is not plain: left, center, or right; default is right.

text

Caption displayed if map is not plain.

layer

Vector style or raster tileset ID; default is usrd

Vector options include:

• Americana-based:
  • Americana (americana)
  • AARoads (usrd), which implements the legacy standards for static maps adopted by the English Wikipedia’s WikiProject U.S. Roads.
• OpenHistoricalMap
  • historic
  • japanese scroll
  • woodblock

Raster options inlcude:

• OpenStreetMap tiles:
  • OpenStreetMap Carto (carto)
  • CyclOSM (cyclosm)
  • Humanitarian (humanitarian)

date

ISO 8601-1 date for OpenHistoricalMap layers.

For each feature

Multiple features can be displayed on a single map. For each additional feature, add a sequential number to the end of the parameter name. For example, the second uses parameters like |commons2=, the third feature |commons3=, and so on. Markers are numbered independently from commons calls, so features defined in both marker2 and commons2, for example, will both appear in the map.

marker-lat

Defines the latitude of a marker to be placed on the map. When lat and long are not defined, this defines the initial center of the map. Multiple markers are defined in the form markerx-lat, where x is the marker's index

marker-lon

Defines the longitude of a marker to be placed on the map. When lat and long are not defined, this defines the initial center of the map. Multiple markers are defined in the form markerx-lon, where x is the marker's index

commons

The map data page to be overlaid on the map. Page names should include the .map extension, and exclude the Data: namespace. Instructions for how to generate maps from OSM data can be found at AARoads:Creating a GeoJSON file from OpenStreetMap

Overwriting styling

The properties of a data layer can be overwritten within the template by defining parameters as shown below, where style is replaced by any of these parameters:

• title
• description
• stroke-color
• stroke-width
• stroke-opacity
• fill
• fill-opacity

stylex

If a single value is put here, it will override all features in layer x with that value. Representing this parameter as a JSON object in the format {"id1": "value1", "id2": "value2"} identifies GeoJSON features in the layer where the key-value pairs in the properties object of the feature match the value to whatever the idy key is in the template JSON object, and the property key to what's defined in the parameter style-keyx (which defaults to title) and then redefines that feature's property to the value in the JSON in the template (represented as valuey). For example, if there are features in layer 1 with name values of "Thomas Vincent Ramos Highway", "Hummingbird Highway", and "Coastal Highway", and you wish for them to be red, green, and blue, respectively, then define the following parameters in the template:

stroke-color1={"Thomas Vincent Ramos Highway": "#f00", "Hummingbird Highway": "#0f0", "Coastal Highway": "#00f"}|stroke-color-key1=name

Note that if you only wish to affect one data layer, a suffix must be given

style

Overrides all features in the map not overwritten by a stylex parameter with this value. This can be represented as a single value or as a JSON object using the same method as the stylex parameters

Comparer

By defining an attribute within the frame with two values prefixed with COMP: and separated by either,, or ; if the labels contain commas, or ### if the labels contain semi-colons, the map will show a scrubber that divides the frame with value1 on the left and value2 on the right, with a slider to adjust the frames of each. All values not defined in this manner will be the same in both views.

Attributes that can be changed between views include commons, marker, layer, and date.

Example:

{{Map|zoom=10|commons=COMP:New Jersey Route 3.map, New Jersey Route 4.map}}

Multiple map switcher

An option for Template:Switcher-style switching of multiple mapframes, where specified parameters like zoom, or frame coordinates, or features are switched between different values. When using, ensure the number of values in each list are the same. If there are more values than switch labels, later ones will be ignored; if there are less, the last value will be repeated for all subsequent labels.

Instructions:

1. Add parameter switch to specify labels for the different options: a list separated by either,, or ; if the labels contain commas, or ### if the labels contain semi-colons. Each label will be displayed with a prefix of "Show ".

   Example: |switch=zoomed out, zoomed mid, zoomed in

2. For each parameter that is to be switched, set its value to SWITCH: followed by a list of values to switch between, again separated by , or ; or ###

   Example: |zoom=SWITCH:4;9;14

   Parameters frame, plain, and text should not be switched

3. Make sure each list has the same number of entries. The position of value in a SWITCH: list corresponds to the same position in the list of labels set in |switch=.

Example:

{{Map|marker-lat=42.360278|marker-lon=-71.057778|text=Boston|zoom=SWITCH:4;9;14|switch=zoomed out, zoomed mid, zoomed in}}

Both this and the comparer can be used in the same template. Comparer entries are combined before switcher entries.

Example:

{{Map
|marker-lat=SWITCH:38.973056, 38.189167; 44.310556, 43.66
|marker-lon=SWITCH:-76.501111, -76.432222; -69.779444, -70.255
|text=Capitals of US States
|switch=capital of Maryland, capital of Maine}}
