The Map data region is a professional edition feature that shows your business data against a geographical background. You can create different types of map, depending on the type of information you want to communicate in your report.

The Map data region consists of the following basic elements:

Title

Map Title describes the theme or subject of the map. The purpose of map title is to tell the viewer of what he is looking at. You can add multiple titles to the Map using the MapTitleDesigner Collection Editor.

For more information, see Create a Map.

Viewport

Viewport refers to the area on the map where data is displayed against a geographical background. It specifies the coordinates, projection system, parallels and meridians, center point, and scale of the map. In other words, it is a map element that actually displays geographical data and occupies most area of the map control depending on the location and dock position of other map elements. For more information, see Create a Map.

The Map Viewport dialog lets you set properties with the following pages.

Legend

A legend on a map provides valuable information to users for interpreting the map data visualization rules such as color, size, and marker type differences for map elements on a layer. By default, a single Legend item already exists in the legends collection which can be used by all layers to display items. You can also create additional legends to use them individually with layers that have associated rules to display items in the legend.

Legends are added in the LegendDesigner Collection Editor. For more information, see Create a Map.

Distance Scale

A distance scale helps a user to understand the scale of the map. Distance on a map is not the same as the actual real-world distance, so a distance scale shows that a certain distance on the map equals a certain distance in a real-world. In distance scale, the distance is displayed in both miles and kilometers. The scale range and values are automatically calculated using the viewport boundaries, projection type, and zoom level. For more information, see Create a Map.

The Map Distance Scale dialog lets you set properties with the following pages.

Note: You can select <Expression...> within these properties to create an expression to determine the value.

Layers

A map is a collection of layers that display data on the map control.

A map can have one or more layers. You can load these layers on top of each other to create a more detailed map. For example, a polygon layer can represent the borders of a country, a line can represent transportation routes, a point can represent the locations and a tile can add a virtual earth background on the map. See, Use Layers for more information.
