Using Spatial Data with SAS/GIS Software

Importing ARC/INFO Data

ARC/INFO software supports several different spatial data formats, but SAS/GIS software can only import spatial data that have been exported from ARC/INFO software in uncompressed transport format (sometimes called E00 files because the transport files have the extension .e00 by default). If you do not know whether a file is compressed, open the file with a host editor. If you can read text in the file, it is not compressed.

To import spatial data in uncompressed ARC/INFO format by using the GIS Spatial Data Importing window:

  1. Select ARC using the Import Type pull-down control.

    The title of the filename field in the Input area changes to ARC/INFO Coverage export filename.

  2. Specify the path to the desired ARC/INFO file, either by typing the path in the filename field or by using the pull-out control to display an Open window, and then by selecting the file from that window.

    By default, SAS/GIS expects ARC/INFO files to have an extension of .e00.

    SAS/GIS allocates the SAS fileref ARCIN to the import path that you specified in the filename field. If you allocate the fileref ARCIN to the desired file before you begin the import process, the filename and path appears in the filename field automatically.

  3. Modify the destination information for the catalog and the spatial data sets, if needed.

  4. Modify the default layers and composites, if needed. See Common Importing Procedures for more information.

  5. 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.
