TiledWebMap

Tiled web map, in short TWM, allows users to dynamically create maps from small (most often 256x256 pixels) images called tiles, that are dynamically pulled from a third party provider's server by using a custom URL. These tiles are later joined and displayed seamlessly as a Highcharts map.

Configuration

In order to use the tiledwebmap series as a base map, firstly import the tiledwebmap.js module.

<script src="https://code.highcharts.com/maps/modules/tiledwebmap.js"></script>

Secondly, set the series type to tiledwebmap. The tiled web map series can be considered a map layer. It does not require any data or GeoJSON geometry to run. The implementer only has to specify which provider should be used to fetch the tiles from. This series doesn’t have information about what region we want to focus at, so in most cases the implementer wants to set either mapView.center and mapView.zoom or mapView.fitToGeometry or add another series with geometry data, which will calculate the proper bounds for the map view. There are additional options such as a theme for the tiles, a subdomain for the provider’s URL and an API key if needed.

Sample code:

series: [{
    type: 'tiledwebmap',
    name: 'Basemap Tiles',
    provider: {
        type: 'OpenStreetMap',
        theme: 'Standard',
        subdomain: 'a'
    }
}]

Alternatively, you can enter your own URL template, and omit all of the aforementioned properties. The URL has to include variables for {x}, {y} and {z}/{zoom} in a given format.

series: [{
    type: 'tiledwebmap',
    url: 'https://yourcustomprovider.com/{x}/{y}/{z}.png'
}]

Generally in Highcharts Maps, the series array can be thought of as layers that are stacked on top of each other, and the ordering of the layers is determined by source order and can be overridden through the index option or the zIndex option.

Providers properties

Highcharts by default supports the following tile providers: OpenStreetMap, Thunderforest, Esri, Stamen, USGS and LimaLabs. Each provider has their own themes and possible subdomains. Tiles are provided in a specific map projection, usually it is a WebMercator projection.

Providers supported natively by Highcharts force map chart configuration to set an appropriate map projection. If the user sets their own projection, which is not supported, there will be a warning in the console and tiles might not load properly. Other providers can be added by using a custom URL in the provider.url property or another provider can be custom built and plugged in.
