The Blazor Map component is ideal for rendering maps from GeoJSON data or other map providers like OpenStreetMap, Google Maps, Bing Maps, etc. Its rich feature set includes markers, labels, bubbles, navigation lines, legends, tooltips, zooming, panning, drill down, and much more.

GeoJSON layer

Bind GeoJSON data to the Blazor Map to render any geometric shape in SVG (Scalable Vector Graphics) for powerful data visualization of shapes. For example, you can render a world map or US map and customize it to the desired look using built-in options in the Blazor Map component. You can also add any number of layers to the Blazor Map.

Geometry types

The geometry types are shapes with straight lines and angles symbolizing structure and order. Coordinates are used to locate a specific point on a grid, known as a coordinate plane. Polygon, MultiPolygon, LineString, MultiLineString, Point, MultiPoint, and GeometryCollection are the supported geometry types.

Geo-imagery visuals

Built-in support for external geospatial imagery services, such as Bing Maps and OpenStreetMap, to visualize satellite, aerial, and street maps, or other kinds of imagery tiles without any external shape inputs. Apart from Bing Maps and OpenStreetMap, users can also render Blazor Maps from various map providers, for example, Google Maps Tile API, TomTom, Mapbox, Esri’s ArcGIS, etc. By using these external services, map data can be located easily.

Using the sublayer, create a map with multiple geometric layers in a single view. For example, render additional geographic features of a country such as rivers, valleys, and more as a sublayer. You can also drill each layer.

Denote a place with symbols or mark messages at the desired latitude and longitude of a location on a map using markers. For example, indicate a particular place on the map of USA using a balloon marker shape. Place any HTML element as a marker and also add multiple markers to the map.

Marker clustering

Display multiple markers in the same location by clustering the markers when they overlap one another. For example, you can use markers to indicate the top 50 cities in the world. If a marker overlaps another, it will be clustered and the total number of markers will be displayed over the cluster.

Data label

Data labels enable users to identify the shapes by displaying their names. Trim or hide labels at intersections with other labels and when they exceed shape bounds.

Create a simple Blazor Map control with bubbles to provide additional information about shapes such as population density, land area, and more. Bubbles are rendered with various magnitudes and colors based on the underlying data values of the shape.

Represent flight route or ship route on a geographic map between two places with navigation lines. It also acts as the connector line that links points on a map. The navigation lines can also be curved.

Color mapping

Categorize the shapes on a map by customizing their color based on the underlying value. The Blazor Map with a rich UI supports two types of color mapping: range color mapping and equal color mapping.

Range color mapping is applied to the shapes in Blazor Maps

Range color mapping

Apply colors to shapes by comparing their values with a desired numeric range. For example, apply colors to the states in the USA based on population density.

Equal color mapping is applied to the shapes in Blazor Maps

Equal color mapping

Differentiate a shape’s fill based on its underlying value and color, using equal color mapping. For example, apply colors to the states in the USA based on a winning candidate.

Desaturation color mapping is applied to shapes in Blazor Maps

Desaturation color mapping

Change the opacity of the shapes by comparing their value with a desired numeric range. Minimum and maximum opacity of shapes can be customized.

Desaturation color mapping with multiple colors are applied to shapes in Blazor Maps

Desaturation with multiple colors

Apply colors to the shape from a gradient by comparing their value with a desired numeric range. Any number of colors can be specified for creating the gradient.


Users can use legends to provide valuable information for interpreting the map with various colors, shapes, or other identifiers based on data and application needs. The interactive Blazor Map control supports two types of legends: default and interactive.

A map with a legend contains swatches of symbols with descriptions to denote the categories of shapes.

Blazor Map is rendered with interactive legends


Use a map with an interactive legend to find the range of an underlying shape’s value on mouse hover.

Zooming and panning

Zoom the map for close-up analysis by pinching the map, scrolling the mouse wheel, clicking the shapes, or by using zooming toolbar; and pan the map for easy navigation across regions. You can also change the zoom level of the initial rendering.

Zooming and panning is enabled in the Blazor Map


Display a tooltip with details about the shape value on mouse hover. Similarly, the tooltip is also displayed for markers and bubbles on a map.

Display a tooltip by hovering over the Blazor Map


Users can drill-down the rendered Blazor Map to display a different shape data located on another layer. For example, in the initial layer you can render the world map and on clicking a particular continent, render it separately on another layer.

Selection and highlight

Select a particular shape on mouse click and highlight on mouse hover to bring it into focus.

Custom shapes

Create a map with custom shapes by rendering your own GeoJSON data to indicate building infrastructure, points of interest, flight/bus seat arrangement, cricket stadium, and more useful information.

Display any HTML element as an annotation at a specific point of interest on a map. For example, place a direction compass image on the map using annotation. You can also add multiple annotations to a map.

You can change the projection of the default rendering map based on your need. The Blazor Map component supports various types of projections namely, Mercator, Rectangular, Miller, Eckert3, Eckert5, Eckert6, and Winkel3.

Title and subtitle

Add a title and subtitle to visualize additional information on Blazor Maps. You can also customize the font and alignment of the title and subtitle.

Customize the look and feel of a map by changing the fill color, background, border, and opacity of shapes. Almost all the elements in the Blazor Map are customizable. It provides built-in palettes with customizable options, by default.

Export or print the rendered Blazor Map to save a local copy for further use.

Export Blazor Map illustration


Export the Blazor Map to a PDF document or in image formats such as SVG, PNG, and JPEG in client-side.

Print Blazor Map illustration

We do not sell the Blazor Map separately. It is only available for purchase as part of the Syncfusion Blazor suite, which contains over 80 native Blazor components, including the Map. A single developer license for the Syncfusion Essential Studio for Blazor suite costs $995.00 USD, including one year of support and updates. On top of this, we might be able to offer additional discounts based on currently active promotions. Please contact our sales team today to see if you qualify for any additional discounts.

You can find our Blazor Map demo here.

No, our 80+ Blazor components, including the Map, are not sold individually, only as a single package. However, we have competitively priced the product so it only costs a little bit more than what some other vendors charge for their Maps alone. We have also found that, in our experience, our customers usually start off using one of our products and then expand to several products quickly, so we felt it was best to offer all 80+ Blazor components for a flat fee of $995/developer. On top of this, we might be able to offer additional discounts based on currently active promotions. Please contact our sales team today to see if you qualify for any additional discounts.

No, this is a commercial product and requires a paid license. However, a free community license is also available for companies and individuals whose organizations have less than $1 million USD in annual gross revenue and five or fewer developers.

A good place to start would be our comprehensive getting started documentation.
