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.
- Polygon layer: Display outlines of areas or markers for the polygon center point. See, Use a Polygon Layer for more information.
- Point layer: Display markers for point locations. See, Use a Point Layer for more information.
- Line layer: Display lines for paths or routes. See, Use a Line Layer for more information.
- Tile layer: Adds a Bing map tiles background. See, Use a Tile Layer for more information.
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.
Map layer element appearance:
- Properties that you set on a polygon layer, line layer and a point layer apply to all map elements on that layer, whether or not the map elements are embedded in the report definition.
- Properties that you set for rules apply to all map elements on a layer. All data visualization options apply only to map elements that are associated with spatial data.
Map Layer Data Dialog
The Map layer Data dialog is used to set up spatial and analytical data for the map control. For more information on spatial and analytical data, see Work with Data.
To access Map Layer Data Properties dialog
- Click the map until the map panes appears.
- Right click the layers pane and select Add <layerName> Layer. This adds a new layer to the map and opens the Map Layer Data Properties dialog
Or, in case you already have a layer added to the map control, then follow these steps:
- Click the map until the map panes appears.
- In the layer pane, right-click the existing layer and select Layer Data to open Map Layer Data Properties dialog.
General
Spatial data source: Select one of the spatial data source connection types:
-
Embedded: The map layer data is loaded from the .shp data source that you embed into the map layer by indicating the .shp file in the Import spatial data from file: field. This field appears below when you select this option.
Spatial fields: Use the plus sign button to add a field, and the X button to delete a field. For each newly added spatial field, you must specify the name and type in the corresponding fields below.
Field name: Enter a name of a spatial field.
Field type: Select the type of a spatial field from the list.
- Linked: The map layer data is linked to the .shp file and is uploaded at report rendering. You select this type of data source by indicating the .shp file in the File Name field that appears.
-
Dataset: The map layer data is loaded from the data source of the report. In the Dataset field and in the Field name field that appear below, select a dataset from the bound data source and a dataset field.
Caution: In Field name, simply type the name of the dataset field that contains spatial data. For example, enter the dataset field name as StateName, not as =[StateName].
-
Analytical data: The map layer data is loaded from the the analytical dataset of the bound report data source. In the Field name field that appears below, you must set the name of the data field that contains spatial data in the Analytical dataset.
Caution: In Field name, enter the data field name as =[StateName], not as StateName.
Analytical Data
Dataset: Select the dataset for the analytical data to be displayed on the map layer.
Match: Use the plus sign button to add a relationship between a spatial data field and an analytical data field.
Spatial field: A field with spatial data that specifies an element on the map surface, for example, boundaries of a country.
Analytical field: A field with analytical data that displays information on the related map element, for example, the country population.
Filters
The Filters page of the Map Layer Data Properties dialog allows you to filter the data that is included in the map. Use the plus sign button to add a filter, and the arrow and X buttons to move or delete filters. You need to provide three values to add a new filter to the collection.
Expression: Enter the expression to use for evaluating whether data should be included in the map.
Operator: Select from the following operators to decide how to compare the expression to the left with the value to the right:
- Equal Only choose data for which the value on the left is equal to the value on the right.
- Like Only choose data for which the value on the left is similar to the value on the right.
For more information on using the Like operator, see the MSDN Web site. - NotEqual Only choose data for which the value on the left is not equal to the value on the right.
- GreaterThan Only choose data for which the value on the left is greater than the value on the right.
- GreaterThanOrEqual Only choose data for which the value on the left is greater than or equal to the value on the right.
- LessThan Only choose data for which the value on the left is less than the value on the right.
- LessThanOrEqual Only choose data for which the value on the left is less than or equal to the value on the right.
- TopN Only choose items from the value on the left which are the top number specified in the value on the right.
- BottomN Only choose items from the value on the left which are the bottom number specified in the value on the right.
- TopPercent Only choose items from the value on the left which are the top percent specified in the value on the right.
- BottomPercent Only choose items from the value on the left which are the bottom percent specified in the value on the right.
- In Only choose items from the value on the left which are in the array of values specified on the right.
Selecting this operator enables the Values list at the bottom. - Between Only choose items from the value on the left which fall between the pair of values you specify on the right. Selecting this operator enables two Value boxes instead of one.
Value: Enter a value to compare with the expression on the left based on the selected operator. For multiple values used with the Between operator, the lower two value boxes are enabled.
Values: When you choose the In operator, you can enter as many values as you need in this list.
Value: Enter a value to compare with the expression on the left based on the selected operator. For multiple values (used with the In and Between operators) separate values using commas.
