The ASP.NET MVC Maps library is a geographical data visualization tool 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 more.

Why choose Syncfusion ASP.NET MVC Maps library?

ASP.NET MVC Maps customization

Easy to customize

To visualize a geometric shape in SVG format in Maps, you can bind GeoJSON data to it. GeoJSON data is light and simple to read. You can render a world map or a US map and alter it with the ASP.NET MVC Maps control’s built-in options to achieve the required layout.

ASP.NET MVC Maps geospatial imaging

Geospatial imaging services

Works with services like Google Maps, Bing Maps, and OpenStreetMap to view satellite, aerial, and street maps by locating map data quickly without the use of any external shape inputs.

ASP.NET MVC Maps marker and bubbles

Markers and bubbles

Markers are notes on maps that indicate specific latitude and longitude points using symbols. Bubbles are used to convey additional information about shapes such as population density and land area. Circle and square bubbles are available.

ASP.NET MVC Maps multilayers

Multiple geometric layers

A map with several geometric layers in a single view can be generated with sublayers. You can render the geographic elements of a country, such as rivers and valleys, as a sublayer. Each layer can be drilled.

ASP.NET MVC Maps adaptive layout

Adapts to any resolution

Maps has a highly responsive layout and an optimized design for desktops, touchscreens, and phones. It works well on all mobile phones that use iOS, Android, or Windows OS.

ASP.NET MVC Maps projection

Custom projections

The ASP.NET MVC Maps component supports Mercator, Equirectangular, Miller, Eckert 3, Eckert 5, Eckert 6, Winkel 3, and Aitoff projections.

ASP.NET MVC Maps zooming

Zooming and panning

Zooming and panning in ASP.NET MVC Maps are fast. Zoom the map by scrolling the mouse wheel, clicking the shapes, or using the zooming toolbar. Pan the map to navigate among regions easily.

ASP.NET MVC Maps globalization

Globalization and localization

An internationalization library is used to globalize number, date, and time values in Maps. All the strings used in the Maps user interface can be localized by users as needed. Localizing UI strings involves using the localization (l10n) library.

ASP.NET MVC Maps rendered with geometry types over OSM map

Geometry types

GeoJSON data contains geometry objects with properties such as geometry types and coordinates. The geometry types are the values present in the geometry objects of the GeoJSON data that specify the type of shape to be rendered, along with the coordinates that help to draw the shape’s boundary line. 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, is used to visualize satellite, aerial, and street maps, or other kinds of imagery tiles without any external shape inputs. In addition to Bing Maps and OpenStreetMap, users can also render maps from various map providers, for example, Google Maps Tile API, TomTom, Mapbox, and Esri’s ArcGIS. By using these external services, map data can be located easily.

ASP.NET MVC Maps with multiple layers


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


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

ASP.NET MVC Maps rendered with marker clustering option

Marker clustering

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

Marker drag and drop

Drag and drop markers to reposition them in the map. After dragging and dropping markers, the marker data source and elements such as marker shape, color, legend, and tooltip content can be changed using supported events.

Color mapping

Categorize the shapes on a map by customizing their color based on the underlying values. The ASP.NET MVC Maps component supports three types of color mapping: range color mapping, equal color mapping, and desaturation color mapping.

Range color mapping applied to the shapes in ASP.NET MVC Maps

Range color mapping

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

Equal color mapping applied to the shapes in ASP.NET MVC Maps

Equal color mapping

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

Desaturation color mapping applied to the shapes in ASP.NET MVC Maps

Desaturation color mapping

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

Desaturation color mapping with multiple colors applied to the shapes in ASP.NET MVC Maps

Desaturation with multiple colors

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


Legends provide valuable information for interpreting the map with various colors, shapes, or other identifiers based on data and application needs. The ASP.NET MVC Maps component supports two types of legends: default and interactive.

ASP.NET MVC Maps rendered with default legend items


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

ASP.NET MVC Maps rendered with interactive legend


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. Also change the zoom level of the initial rendering.

Displays a tooltip on moving mouse over the ASP.NET MVC Maps


The tooltip displays details about the shape value on mouse hover. Tooltips are also displayed for markers and bubbles on a map.

Drill down

Drill down in rendered ASP.NET MVC Maps to display different shape data located on another layer. For example, the initial layer may render the world map and on clicking a particular continent, the continent alone will render separately on another layer.
