Using Spatial Data with SAS/GIS Software

Importing DLG Data

Select DLG by using the Import Type pull-down control.
The title of the filename field in the Input area changes to 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.
