To import spatial data
in SASGRAPH format using the
GIS Spatial Data Importing window, complete the following steps:
-
Select
SASGRAPH from the
Import Type drop-down menu.
The title of the filename
field in the
INPUT pane changes to
SAS/GRAPH data set.
-
Specify the library
and data set name of the desired
SAS/GRAPH data, either by typing
the data set name in the data set name field, or by clicking the arrow
to display a
Select A Member window and then
selecting the data set from that window.
-
Select the variables
from the
ID Vars field that you want to use
as ID variables. ID variables are variables whose values uniquely
identify unit areas in the map. Typical ID variables in
SAS/GRAPH
maps are COUNTRY, ID, STATE, and COUNTY. A separate layer is created
for each ID variable. The ID variables must be selected in hierarchical
order. For example, if the data set contains both STATE and COUNTY
variables, then STATE must be selected before COUNTY.
-
Modify the destination
information for the catalog and the spatial data sets, if needed.
-
Modify the default layers
and composites, if needed. For more information, see the following:

Click
Import to import the data. When the import process is complete, a message
is displayed in the window message bar to indicate whether the import
was successful. You can proceed with another import or close the window
to display the newly imported map.
