Add a WMS Source
WMS is a standard protocol for serving georeferenced map images from a remote server, commonly used by government and scientific data providers. In Maptoolkit Maps JS, you connect a WMS endpoint as a raster tile source by constructing the required GetMap request URL template. Use this to overlay cadastral data, environmental monitoring layers, or any WMS-compatible spatial dataset on your map.

const map = new maptoolkit.Map({
container: 'map',

center: [13.0, 47.5],
zoom: 6,
attributionControl: { compact: false }
});
map.addControl(new maptoolkit.NavigationControl(), 'top-right');
map.on('load', () => {
map.addSource('wms-source', {

Use the Maptoolkit Connector. Create an interactive map with zoom level 6, centered around [13.0, 47.5]. Add a WMS raster overlay from https://ows.terrestris.de/osm/service (OSM-WMS layer).
