Other Maps in Blazor Maps Component
26 Jun 20249 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 Blazor 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.
@using Syncfusion.Blazor.Maps
<SfMaps>
<MapsLayers>
<MapsLayer UrlTemplate="http://api.tomtom.com/map/1/tile/basic/main/level/tileX/tileY.png?key=subscription_key" TValue="string">
</MapsLayer>
</MapsLayers>
</SfMaps>
Enable zooming and panning
Tile Maps layer can be zoomed and panned. Zooming helps to get a closer look at a particular area on a Maps for in-depth analysis. Panning helps to move Maps around to focus the targeted area.
@using Syncfusion.Blazor.Maps
<SfMaps>
@* To zoom and pan *@
<MapsZoomSettings Enable="true">
<MapsZoomToolbarSettings>
<MapsZoomToolbarButton ToolbarItems="new List<ToolbarItem>() { ToolbarItem.Zoom, ToolbarItem.ZoomIn, ToolbarItem.ZoomOut,
ToolbarItem.Pan, ToolbarItem.Reset }"></MapsZoomToolbarButton>
</MapsZoomToolbarSettings>
</MapsZoomSettings>
<MapsLayers>
<MapsLayer UrlTemplate="http://api.tomtom.com/map/1/tile/basic/main/level/tileX/tileY.png?key=subscription_key" TValue="string">
</MapsLayer>
</MapsLayers>
</SfMaps>
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 MapsMarker class. Navigation lines can be added on top of the tile Maps layer for highlighting a path among various places by setting the corresponding location’s coordinates of latitude and longitude in the MapsNavigationLine.
@using Syncfusion.Blazor.Maps
<SfMaps>
<MapsZoomSettings ZoomFactor="4"></MapsZoomSettings>
<MapsCenterPosition Latitude="29.394708" Longitude="-94.954653"></MapsCenterPosition>
<MapsLayers>
<MapsLayer UrlTemplate="http://api.tomtom.com/map/1/tile/basic/main/level/tileX/tileY.png?key=subscription_key" TValue="string">
@* Add markers *@
<MapsMarkerSettings>
<MapsMarker Visible="true" Height="25" Width="15" DataSource="Cities" TValue="City">
</MapsMarker>
</MapsMarkerSettings>
@* Add navigation line *@
<MapsNavigationLines>
<MapsNavigationLine Visible="true" Color="blue" Angle="0.1" Latitude="new double[]{34.060620, 40.724546}"
Longitude="new double[]{-118.330491,-73.850344}">
</MapsNavigationLine>
</MapsNavigationLines>
</MapsLayer>
</MapsLayers>
</SfMaps>
@code{
public class City
{
public double Latitude { get; set; }
public double Longitude { get; set; }
public string Name { get; set; }
}
private List<City> Cities = new List<City> {
new City { Latitude = 34.060620, Longitude = -118.330491, Name="California" },
new City{ Latitude = 40.724546, Longitude = -73.850344, Name="New York"}
};
}
Adding sublayer
Any GeoJSON shape can be rendered as a sublayer on top of the tile Maps layer for highlighting a particular continent or country in tile maps by adding another layer and specifying the Type property of MapsLayer to SubLayer.
@using Syncfusion.Blazor.Maps
<SfMaps>
<MapsLayers>
<MapsLayer UrlTemplate="http://api.tomtom.com/map/1/tile/basic/main/level/tileX/tileY.png?key=subscription_key" TValue="string">
</MapsLayer>
@* To add geometry shape as sublayer *@
<MapsLayer ShapeData='new {dataOptions = "https://cdn.syncfusion.com/maps/map-data/africa.json"}'
Type="Syncfusion.Blazor.Maps.Type.SubLayer" TValue="string">
<MapsShapeSettings Fill="blue"></MapsShapeSettings>
</MapsLayer>
</MapsLayers>
</SfMaps>
Enable legend
The legend can be added to the tile Maps by setting the Visible property of MapsLegendSettings to true.
@using Syncfusion.Blazor.Maps
<SfMaps Format="N0" EnableGroupingSeparator="true">
<MapsZoomSettings Enable="true">
<MapsZoomToolbarSettings>
<MapsZoomToolbarTooltipSettings FontFamily="inherit"></MapsZoomToolbarTooltipSettings>
</MapsZoomToolbarSettings>

</MapsLegendSettings>
<MapsTitleSettings Text="Top 10 populated cities in the World">
<MapsTitleTextStyle Size="16px" FontFamily="inherit" />
