The
SAS/GIS batch import
process enables you to use SAS Component Language (SCL) code to import
data into
SAS/GIS. The import is done without using the interactive
GIS
Spatial Data Importing window, or even invoking
SAS/GIS.
This feature can be useful when you have large amounts of data to
import. For example, it lets you set up a batch job to run overnight.
The
SAS/GIS batch import
process enables you to define the values that are needed for the import
through macro variables and SAS filerefs. After you define the values,
you then call an SCL entry to actually initiate the import. The process
has three main steps:
-
Specify the input parameters.
Include the definitions
of the type of data to import, the location of the input spatial data,
and any other specifications for identification variables (not necessary
for all import types). You define the input parameters either by setting
the values of macro variables or by assigning filerefs (depending
on the import type).
-
Specify the output parameters.
Include the library
in which the output spatial data sets and catalogs will be stored.
Also include the name specifications for catalogs, data sets and catalog
entries. Indicate whether they will be created, replaced, or updated.
You define all output parameters by setting the values of macro variables.
-
Initiate the batch import.
Execute the SASHELP.GISIMP.BATCH.SCL
entry to start the batch import process. You do not pass any parameters
directly to the SCL entry; the parameters must all have been defined
through macro variables and filerefs before you call the SCL entry.
