You can import
SAS/GRAPH
map data sets from both the original MAPS library as well as the newer
data sets in the MAPSGFK library.
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 file name.
-
Specify the library
and data set name of the desired
SAS/GRAPH data. Either enter the
data set name in the data set name field or click the arrow to display
a
Select A Member window. Then select the
data set from that window.
-
Select the variables
from the
INPUT 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, that is, select the ID variable representing
the largest area first. 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.
