Template:Map with marks/styles.css

Shows an image of a map, and draws user-specified images/icons on top of it using latitude/longitude coordinates.

Markup	Result
Simple map with a single marker, custom size, and no minimap {{Map with marks \| width=400 \| height=150 \| lat=37.8 \| lon=-122.4 \| zoom=5 \| minimap=false \| { "lat": 37.8, "lon": -122.4 } }}
Two markers with labels - one as diamond shape, one uses an image from Commons Text label can be customized with all of Vega text mark parameters by prepending "text" to their name {{Map with marks \| lat=40.816667 \| lon=14.433333 \| zoom=6 \| {"lat": 40.816667, "lon": 14.433333, "shape": "diamond", "size": 70, "offsetY": -10, "text": "Mount Vesuvius", "textFontWeight": "bold", "textFontSize": 16, "textColor": "#2A4B8D"}, {"lat": 40.948333, "lon": 15.635556, "img": "Volcano red 32x32.svg", "width": 16, "height": 16, "offsetY": -20, "text": "Mount Vulture", "textFontWeight": "bold", "textFontSize": 16, "textColor": "#2A4B8D"} }}
One marker with labels on a blank map {{Map with marks \| style=osm \| lat=40.816667 \| lon=14.433333 \| zoom=6 \| {"lat": 40.816667, "lon": 14.433333, "shape": "diamond", "size": 70, "offsetY": -10, "text": "Mount Vesuvius", "textFontWeight": "bold", "textFontSize": 16, "textColor": "#2A4B8D"}, }}
Data from Commons Dataset Same as above, but this time the data is stored on Commons in a table Data:Sandbox/Yurik/Street map with marks sample.tab {{Map with marks \| lat=40.948333 \| lon=15.635556 \| zoom=6 \| table=Sandbox/Yurik/Street map with marks sample.tab}}	(See or edit source data)
Show all Armenian heritage sites, by querying it from Wikidata The query result should have the same columns (fields) as in the other examples (`text, img, ...`), except coordinates should be returned as `coord` column {{Map with marks \| lat=40.347 \| lon=47.260 \| zoom=6 \| colorScaleField=type \| wdqs= # Each location should show only once. This query may output all the same values as in the other examples, such as "text", "img", and others. SELECT (SAMPLE(?coord) as ?coord) (SAMPLE(?type) as ?type) WHERE { ?item wdt:P3170 ?heritageId . ?item wdt:P625 ?coord . ?item wdt:P31 ?type . } GROUP BY ?item }}	(See Wikidata query)
{{Map with marks \| lat=-33.8688 \| lon=151.2093 \| zoom=10 \| { "lat": -33.8688, "lon": 151.2093, "img": "Opera_House_and_ferry._Sydney.jpg", "width": 48, "height": 36, "text": "Sydney", "textFontWeight": "bold", "textFontSize": 20, "textColor": "#00f", "textAlign": "right", "textDx": -30 } }}

The data template parameter must be a comma separated list of "JSON" objects. Each object starts with a "{", has a list of comma separated key-value pairs, and ends with a "}". The key may be one of the following values (used no more than once per each object):

Built-in marker shapes
shape	"circle" (default), "square", "cross", "diamond", "triangle-up", "triangle-down" (docs)
color	shape fill color, e.g. "#ff0000" (red - default)
strokeColor	shape outline color
size	shape size (number)
Text labels (see more info)
text	Label text
textAlign	Label's horizontal alignment relative to the marker - "left", "right", "center". By default, left for LTR, right for RTL languages.
textBaseline	Vertical alignment: "middle" (default), "top", "bottom"
textColor	Label text color, e.g. "#ff0000" (red)
textDx, textDy	Horizontal and vertical distance from the marker
angle	Draw text at an angle
radius/theta	Radial positioning of the label relative to the marker
font, fontSize, fontWeight, fontStyle	Font name, size, boldness, and style
Image markers
img	URL of an image, e.g. wikirawupload:{{filepath:Volcano red 32x32.svg\|32}}
height, width	Size of the image
offsetX, offsetY	Shift the center of the image on the map

Template data

Shows an image of a map, and draws user-specified images/icons on top of it using latitude/longitude coordinates.

Template parameters[Edit template data]
Parameter		Description	Type	Status
data	`1`	Comma separated list of JSON objects that describing what data to draw on the map	String	suggested
width	`width`	Total width of the graph	Number	optional
height	`height`	Total height of the graph Default Half of the width	Number	optional
padding	`padding`	no description	Number	optional
lat	`lat`	Latitude of the map's center	Number	optional
lon	`lon`	Longitude of the map's center	Number	optional
zoom	`zoom`	Map zoom level (0..18)	Number	optional
lang	`lang`	The language code of the language to use to draw the labels on the map. Use special value 'local' to draw the labels in the language of the area being depicted. Uses the page language by default.	String	optional
wdqs	`wdqs`	An optional Wikidata query to use instead of the data - the query would generate a list of items just like data, but it must contain a "coord" field with the location	String	optional
colorScaleField	`colorScaleField`	If given, this data field will be used to make dots of different color, one color per unique value of this field	String	optional
minimap	`minimap`	If set, 0 or false will always hide the map, and 1 or true will always show it. Make sure the map is big enough include the minimap. By default, the map will be shown for zoom levels 5+ if the map is sufficiently large	Boolean	optional
