<mapml-viewer>

The <mapml-viewer> is a declarative vocabulary for Web mapping that extends HTML to include modern Web maps. It is a pilot / reference implementation of the proposed and evolving Map Markup Language Web standard.

Installation

$ npm install @maps4html/web-map-custom-element

See instructions for further details.

Usage

You create a map with one or more layers via the <mapml-viewer> HTML tag. Add layers via the <layer-> tag with content OR a src attribute pointing to a MapML document (must be served as either text/mapml or application/xml content type):

<mapml-viewer projection="OSMTILE" zoom="0" lat="0.0" lon="0.0" controls>
  <layer- label="OpenStreetMap" src="https://geogratis.gc.ca/mapml/en/osmtile/osm/" checked></layer->
</mapml-viewer>

OR inline content

<mapml-viewer projection="OSMTILE" lat="10" lon="0" zoom="1" controls>
  <layer- label="OpenStreetMap" checked>
    <map-extent units="OSMTILE">
      <map-input name="z" type="zoom" value="18" min="0" max="18"></map-input>
      <map-input name="x" type="location" units="tilematrix" axis="column" min="0" max="262144"></map-input>
      <map-input name="y" type="location" units="tilematrix" axis="row" min="0" max="262144"></map-input>
      <map-link rel="tile" tref="https://tile.openstreetmap.org/{z}/{x}/{y}.png"></map-link>
    </map-extent>
  </layer->
</mapml-viewer>
