Other Maps in React Maps component

01 Dec 2022 / 4 minutes to read

Apart from OpenStreetMap and Bing Maps, you can also render Maps from other online map service providers by specifying the URL provided by those providers in the urlTemplate property. The URL template concept has been implemented in such a way that any online map service providers using the following template can benefit from previewing their Map in the Syncfusion React Maps component.

Sample Template: https://< domain_name >/maps/basic/{z}/{x}/{y}.png

  • ”${z}” - It represents zoom factor (level).
  • ”${x}” - It indicates tile image x-position (tileX).
  • ”${y}” - It indicates tile image y-position (tileY).

In this case, the key generated for those online map service providers can also be appended to the URL. This allows to create personalized Maps with your own content and imagery.

Following is an example of how to add a TomTom map. You can generate an API key by following the steps in this link and then adding the key to the URL.

Adding markers and navigation line

Markers can be added to the layers of tile Maps by setting the corresponding location’s coordinates of latitude and longitude using MarkerDirective tag. Navigation lines can be added on top of an tile Maps layer for highlighting a path among various places by setting the corresponding location’s coordinates of latitude and longitude in the NavigationLineDirective tag.
