| Using Spatial Data with SAS/GIS Software |
To import spatial data in Dynamap format by using the GIS Spatial
Data Importing window:
- Select Dynamap by using the Import Type pull-down
control.
The title of the filename field in the Input area changes
to Dynamap basic data record filename.
- Specify the path to the desired Dynamap basic
data record 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. The basic data record file is a Type 1 Dynamap file,
and it contains a record for each line segment in the file. This file is required.
SAS/GIS software allocates the SAS fileref GDT1 to the
import path that you specified in the filename field. If you allocate the
fileref GDT1 to the desired file before beginning the import process, the
filename and path appear in the filename field automatically.
- Select [Other Files...]
A window appears and displays
filename fields for the
remainder of the Dynamap files that are needed. If the files are in the same
directory as the basic data record file, the path is specified automatically.
Specify the following files:
- Shape coordinate points
- Provides additional coordinates that describe
the shape of each line segment, for example, a curve in the road. These coordinates
are SAS/GIS detail points. This file is a Type 2 Dynamap file and has a corresponding
fileref of GDT2. This file is required.
- Index to alternate feature names
- If a line segment has more than one feature
name, for example, Main St. and State Highway 1010, the names are in this
file. This file is a Type 4 Dynamap file and has a corresponding fileref of
GDT4. This file is optional and is not selected by default. To read in the
data from this file, select the Read On/Off checkbox.
- Feature name list
- Provides a list of all unique feature names.
This file is a Type 5 Dynamap file and has a corresponding fileref of GDT5.
This file is optional and is not selected by default. To read in the data
from this file, select the Read On/Off checkbox.
- Additional address and ZIP code data
- Provides additional address range information
if the address information cannot be presented as a single address range.
This file is a Type 6 Dynamap file and has a corresponding fileref of GDT6.
This file is optional and is not selected by default. To read in the data
from this file, select the Read On/Off checkbox.
Select [OK ]when you have specified the
paths for the Dynamap files to return to the GIS Spatial Data Importing window.
- 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.
