Interactive ASP.NET Web Forms Maps Control

GeoJSON

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

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. Apart from Bing maps and OpenStreetMap, you can also render maps from various map providers, like, Google Maps. By using external services, the map data can be located easily.

Multilayers

Using sublayer, you can 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.

• Multilayers example

Marker

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

• Marker template example

Data label

Data labels on the maps provide identification for the shapes by displaying their names. Hide the labels if they exceed shape bounds.

• Data labels example

Bubble

Create a simple map with bubbles to denote 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.

• Bubbles example

Color mapping

Categorize the shapes on a map by customizing their colors based on the underlying value or by comparing their value with a desired numeric range. For example, apply colors to the states in the US based on population density.

Zooming and panning

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

• Zooming and panning example

Tooltip

The ASP.NET Web Forms Maps control displays the details about the shape value using a tooltip by hovering the mouse over the shape.

Drill-down

You can drill-down the rendered maps 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.

• Drill-down example

Selection and highlight

Select a particular shape on mouse click and highlight on mouse hover to bring the center of attraction over other shapes on a map.

• Selection and highlight example

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.

Appearance

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 Maps are customizable. The ASP.NET Web Forms Maps control also provides built-in palettes with customizable options, by default.
