Template:Map with marks
 | This template uses TemplateStyles: |
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 <syntaxhighlight lang="wikitext">{{Map with marks | width=400 | height=150 | lat=37.8 | lon=-122.4 | zoom=5 | minimap=false | { "lat": 37.8, "lon": -122.4 } }} </syntaxhighlight> |

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 |
