Configuring an information link with map data

When the geographical data is located in a database and an information link is used to retrieve the data, you must perform the a number of steps when creating the column elements if you want the end users of the information link to be able to create map charts without further configuration.

Before you begin

Information links can only be created using the installed client. See Information Designer and subtopics for details about information links.

Procedure

If you only have a binary WKB column, you can use Spotfire to create the necessary coordinate columns, as described in Configuring WKB data for use with maps. Place the resulting coordinate columns in the server database to make it easier to use the geographical data later on. The Geometry column should be of data type BLOB and the coordinate columns should be of data type Real.
At the creation of the column elements in Information Designer, go to the Properties section on the Column Element tab.
For each column element, expand the Properties field, click Add and type MapChart.ColumnTypeId in the Property name field.
In the Value field, type Geometry, XMax, XMin, YMax, YMin, XCenter or YCenter, depending on which column you are defining.
Save the column elements.
