To add custom polygon
data into an existing SAS Visual Analytics 7.4 environment, there
are certain requirements. By default, SAS Visual Analytics supports
country- and state-level polygons for regional overlays in geographic
visualizations. Data for these levels is provided as part of the included
GfK license.
The necessary steps
to access your own custom polygons in SAS Visual Analytics are provided.
Polygon data is usually provided in shape files and needs to be imported
into SAS.
Examples are provided
for US counties and for German provinces, but the information applies
to all polygon sets for which the correct data structure is provided.
Some steps might need modification depending on the environment, file
types, or formats used.
CAUTION:
Steps to
modify an existing SAS configuration and related data files are included.
Be sure to back up
the current SAS environment before loading polygon data.
