ढाँचा:OSM Location map
Old John Tower in Bradgate Park, Leicestershire |
This template provides a map in a frame, for any location and scale. At its simplest it can simply show the OpenStreetMap image and a scale indicator for a given area of land. Optionally a range of marker, label and annotation tools are available to include location markers, labels, numbered dots, a heading, caption, mini-locator map and overlays. The map also provides a link to a full-screen interactive 'maplink' version.
Purpose
OSM Location map allows an editor to include a map in a frame for anywhere in the world, at any scale from the whole world down two one or two streets. It makes use of the OpenStreetMap mapping data, and enables a place-based page or topic to simply show the area being described, without the need for pre-determined map templates. The underlying map will be updated and improved automatically as the OSM data develops.
The template can also show multiple marks, images and labels (currently limited to ten). The template makes use of {{Graph:Street map with marks}}, which allows unlimited numbers of marks and labels, utilises a different coding mark-up, and is particularly suited to using data directly from a Wikidata source.
The resulting framed map also has a link to a full-screen version, which opens at the same location, above the current page. This has a richer map interface, can be re-scaled and panned by the user, has optional thumbnail images and captions for the marker points, and can also access a wide range of maps, satellite images etc. (The fullscreen option uses the <maplink> mapping provision.)
A rough guide to the scale of the map is provided in the bottom left corner. This is only a guide, as the projection means the scale changes depending on the latitude. Some allowance has been made for this, but only in large 20 degree chunks.
Comparison with {{Maplink}}
From May 2018 it has also been possible to create a map in a frame via {{Maplink}}, which in some respects does a similar job to OSM Location map. In both cases a static map image can be added to an article, for anywhere in the world, pulling in the map from OpenStreetMap data. The differences are in what they can and can't add to the base map. Maplink, in both its framed and fullscreen versions, can only add either points (numbered or icon-style pointy dots), or various lines and areas can be imported from OpenStreetMap via wikidata Q values (such as boundaries, roads, rivers etc). Thus the framed map and fullscreen version will show identical information. The OSM Location map on the other hand, cannot add the Q value lines and areas except to the fullscreen click-through, but can use the framed map to show a much richer selection of dots, shapes, overlays, images and especially text to convey specific details relevant to a particular article.
Usage
- Minimal version
- an unadorned map centred on a latitude and longitiude coordinates, via a {{coord}} value. Set the zoom to give a scale that fits the subject (0=whole world, 18=a street). With just these options set, all other parameters use the defaults, or are left unused. It gives a link to the full screen version.
{{OSM Location map <!--These parameters are the only essential items-->
| coord = {{coord|53.41459|-4.3341279}} <!--latitude and longitude - eg as a +/- decimal. -->
| zoom = 15 <!--(1=whole world, 18=a street)-->
}}
|
- Single marker
- Using mostly default settings, with a Red pog marker and label, and some additional info for use on the full screen version.

Multiple markers, labels and/or images
In addition to the un-numbered mark parameters, there are 30 numbered ones. These are otherwise identical to the one above, but the name terminates in a number (1-30). Each mark and label has its own set of parameters (|mark1=
, |mark-coord1=
, |label1=
, |label-pos1=
etc...|mark2=
, |mark-coord2=
, |label2=
, |label-pos2=
etc.) Mark1
acts as a 'master marker' for subsequent parameters. Values given to the 'mark1 set' are inherited by the other numbered sets, which avoids repetition.
Minimap
There is a built-in map of the world option, which will act as a mini locator map and automatically adds a red locator dot (minimap = on
). Unfortunately it is too general for most purposes, so making use of an existing 'Location map' file is possible. This is can be seen in the Llanfechell map example, it is not very automated. The width and height of the map both have to be specified (and it is up to you to not distort the map dimensions). An optional locator dot can be placed by specifying the minipog-x and -y values, using the same scale values as mini-width and -height. With an origin in the top left of the minimap, the minipog can be placed over the relevant point on the minimap.
| minimap = file <!--this minimap is used in the Llanfechell example above-->
| mini-file = Wales relief location map.jpg
| mini-width = 70
| mini-height = 90
| minipog-x = 25
| minipog-y = 4
| scalemark = 66 <!-- shifts the scalemark further to the left -->
If the area of the actual map is a large portion of the mini-map, an open red box can be included instead of a dot, to show the bounds of the main map. To use this feature, simply specify the width of the required box: minimap-boxwidth=xx
where xx = the pixel width of the box. In general anything much below xx=15 will be better served by a dot. The required width will require some trial and error to pin down. The box height is then matched in proportion to the actual map.
Alternative marks
Instead of using the standard 'Red pog' for mark points on the map, other images can be used. Any image from Wikimedia Commons can be specified. The Pentre Ifan example above uses 'Archaeological site icon (red).svg'. If a particular image file is specified in mark1=
, all subsequent marks will use it as well unless they name their own image file. If the image is not square, a dimension value also needs to be set (width ratio for a height of 1)
Transparent overlay
Leicester Castle and the line of the medieval town walls |
A marker image does not have to be small and opaque. A larger overlay image (with a transparent background) can be used to show particular features not included in the base map, such as a town's former walls (see the adjacent map). Such images can be created in several ways (such as tracing over a copy of the base map); they are invoked like any other marker image file.
Text effects
Where label text is too long to fit on a single line, two further label line can be used: labela =
and labelb =
.
It is possible to specify a label-angle =
, which will pivot the label text around the centre of the marker point by the specified angle. If mark-size is set to zero, this has the effect of a free-floating label with no marker, useful for various geographic and linear features. (This is illustrated by the 'Preseli Hills' text on the Pentre Ifan map). For stylistic consistency all settlement and building names should not be given an angle.
Numbered dots
Listed buildings in Stoneygate 1 2 3 4 5 6 |
If numbered dots are needed, instead of (or as well as) text labels, this can be achieved using the built in shapes. For example, shape1=n-circle
will place a numbered dot at that coord position (or l-circle
for letters). Generally it is much better to use the dots in sequence, so each numbered mark gives a numbered dot, and they will match the full screen ones. If auto-caption=1
then the caption will generate a numbered list using the mark-title
entries. For example:-
{{OSM Location map
| coord={{coord|52.620|-1.112}}
| float=left| zoom =15
| width = 200 | height = 300
| mark-coord1 = {{coord|52.6180|-1.11189}}
| mark-title1 = St John The Baptist Church
| shape1=n-circle
| shape-color1=blue
| shape-outline1=white
| mark-size1=16
| mark-coord2 = {{coord|52.61819|-1.11035}}
| mark-title2 = Congregational Church
| mark-coord3 = {{coord|52.62324|-1.11179}}
| mark-title3 = Eastfield, Stanley Road
| mark-coord4 = {{coord|52.62123|-1.111297}}
| mark-title4 = Stoneygate School
| mark-coord5 = {{coord|52.62009|-1.11241}}
| mark-title5 = The Firs
| mark-coord6 = {{coord|52.61936|-1.11510}}
| mark-title6 = White House
| caption = Listed buildings in Stoneygate
| auto-caption=1
}}
The other built-in shapes can be used in the same way (n-square
, n-diamond
etc.). The shape-outline1=
value sets the colour for the number (unlike normal, when it sets the shape-outline), and as with the others, only the mark1
parameter values need to be set, to establish the default for this map, which can be overridden as required. The numbered1..2..3 etc
parameters can override the automatic numbers or letters to use your own values for each mark. {{Flushing Meadows-Corona Park map}} is a useful real life example in template form.

Parameters
Underlying technologyOSM Location map itself has no map or display ability of its own. Everything within the frame is produced through the template {{Graph:Street map with marks}}, created by User:Yurik. This in turn calls internal processes that turn all the data supplied at edit time into a rendered bitmap image, so that there is no calculation overhead by the time the page is read by a user, any more than any other commons image. Whilst the map is being edited and previewed, the page is supplied with a rasterised image, collating the base-map, marks, labels, etc. on the fly. It will be particularly noticeable on small fonts that when the 'Publish Changes' button is pressed, the resulting bitmap has much worse fonts than the preview. (Maybe this will be improved at some point). The process of updating the map image and providing the right bitmap is all handled internally and invisibly. One of the consequences of the 'bitmap' solution, which is different from the standard {{Location map}} method, is that there is no text or objects on the final image, so there is no possibility of adding wikilinks within the template. The full screen option, which can be clicked through from below the map, provides an entirely different mapping approach, using the same base-map data. This provides an interactive map that can be panned and zoomed. It also replicates (although at present only as numbered markers) the various marks from the page map. These can then be given more content, by way of a title, caption and image. The caption and title can then be given all the wikilinks and other markup features that may be desired, providing a map-based page that will offer another way of engaging with the article content. Future development of the various mapping technologies is likely to result in further options for showing maps on Wikipedia. In particular, something more like the fullscreen interactive map, but within a frame, is likely to emerge. It has a much higher processor overhead than the bitmap based solution, which seems to be one reason for a slow and cautious development. The most likely main use of that might be within info-boxes, where the whole map is automatically generated from already available data. This, on the other hand, is better suited to a hand-edited map, in which the area displayed and the selection of items and labels included are selected, edited, and added to, to suit the specifics of the subject in hand. A further approach, which is not currently supported within this template, but is available via the inderlying 'Graph' template, is to draw the data from Wikidata, using a query that provides the selection of marks requested. The 'Graph' technology used here is described as under development, so while it is highly likely that this or a similar solution will still be available, it may evolve over time. |
