A geo map helps you
analyze data in the context of a location. It displays your data as
a bubble plot that is overlaid on a geographic map. Each bubble is
located at a geographic location or at the center of a geographical
region.
Many types of data have
a spatial aspect, including demographics, marketing surveys, and customer
addresses. For example, if a user needs to evaluate population data
for U.S. Census tracts, a report designer could display the information
in a table. However, it would be easier and more effective for the
person using the report to see the information in the context of the
geography of the tracts. When evaluating information that has a spatial
component, users might find it easier to recognize relationships and
trends in the data if they see the information in a spatial context.
You can add a geo map
object only if the report uses data items from a data source that
is enabled for geographic mapping. A geo map requires a geography
variable with the role type of geography. If you change a category
data item to geography, then you prompted for latitude and longitude
data items. However, it does not have to be a drill-down hierarchy.
