|Using Spatial Data with SAS/GIS Software
To import spatial data in Digital Line Graph (DLG)
format by using the GIS Spatial Data Importing window:
- Select DLG by using the Import Type pull-down
The title of the filename field in the Input area changes
Digital Line Graph filename.
- Specify the path to the desired DLG file, either
by typing the path in the filename field or by using the pull-out control
to display an Open window, and then selecting the file from that window. SAS/GIS
software checks whether the DLG file type is Standard or Optional and processes
the types accordingly.
SAS/GIS allocates the SAS fileref DLGIN to the import
path that you specified in the filename field. If you allocate the fileref
DLGIN to the desired file before beginning the import process, the filename
and path appear in the filename field automatically.
- 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. No more than one layer of each type can be created from
a DLG file. The fields for any layer types that cannot be created are grayed.
- 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.
