|Using Spatial Data with SAS/GIS Software
To import spatial data in SAS/GRAPH format by using the GIS Spatial
Data Importing window:
- Select SASGRAPH using the Import Type pull-down
The title of the filename field in the Input area changes
SAS/GRAPH data set.
- Specify the library and data set name of the
either by typing the data set name in the data set name field or by using
the pull-out control to display a Select A Member window, and then by selecting
the data set from that window.
- Select the variables in the input data set that
you want to use as ID variables by selecting them in the ID Vars field. 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.
See Common Importing Procedures
for more information.
- Select [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.
