Unicode Icons

Unicode defines many icons which can be used either directly or via their HTML codes, e.g.:

🎂 🎂 🎂

A drawback of Unicode icons is, that the display will differ from system to system as they depend on the available Fonts.

Self defined icons

You may upload images to your repository and use them via a relative image link:

<img data-src='img/foobar.svg'>

This will include the image from your repository (when uploaded to your 'img' directory).

Font Awesome Icons

Font Awesome 5 Free is included in OpenStreetBrowser, therefore you can use, e.g.:

<i class="fas fa-compass"></i> <!-- solid -->
<i class="far fa-compass"></i> <!-- regular -->

You can use normal CSS to modify its look, e.g.

<i style="color: red;" class="fas fa-compass" aria-hidden="true"></i>

Mapbox Maki Icons

Mapbox Maki Icons 5 are also included in OpenStreetBrowser. They can be accessed as images with protocol 'maki', e.g.:

<img data-src="maki:park">

This will include the park-15.svg icon. Mapbox Maki icons come in two sizes: 11 and 15. Default is 15, if you want to use 11 pass the size parameter with value 11:

<img data-src="maki:park?size=11">

You can pass URL options to the icon to modify its look. Note that every icon is a SVG path and all style options are available:

<img data-src="maki:park?size=11&amp;fill=red&amp;stroke=black&amp;stroke-width=0.5">

Temaki Icons

Temaki icons are additions to the Mapbox Maki Icons with the difference that they only exist in to size of 15px.

<img data-src="temaki:shinto">
<img data-src="temaki:shinto?fill=red">

Markers

Simple syntax (example: a black line):

<img data-src="marker:line?width=3&amp;color=black">
{{ markerLine({ width: 3, color: 'black' }) }}

The following marker types are available: line, polygon (a rectangle), circle, pointer

The following style parameters are possible:

• color: outline color, default #000000.
• width: outline width, default 3.
• offset: outline offset, default 0.
• fillColor: color of the fill, default value of color. If no color is set, use #f2756a.
• fillOpacity: opacity of the fill, default 0.2.
• dashArray: outline dashes, e.g. 5,5'. Default: none`.
• dashOffset: offset of outline dashes. Default: 0.

Syntax with multiple symbols (example: a white line with a black casing). Only styles which are listed in the styles parameter will be used. Instead of style:default:width use style:width:

<img data-src="marker:line?styles=casing,default&amp;style:width=2&amp;style:color=white&amp;style:casing:width=4&amp;style:casing:color=black">
{{ markerLine({ styles: 'casing,default', 'style:casing': { color: 'black', width: 4 }, default: { color: 'black', width: 2 }}) }}

You can use the evaluate function, to emulate a fake object (e.g. for map keys). The following example would draw a line, which looks like the symbol which is generated by this category for an OSM object with the tags highway=primary and maxspeed=80:

{{ markerLine(evaluate({ "highway": "primary", "maxspeed": "80" })) }}
