To import spatial data
in Dynamap format using the
GIS Spatial Data Importing window, complete the following steps:
-
Select
Dynamap from the
Import Type drop-down menu.
The title of the filename
field in the
INPUT pane 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 clicking the arrow to display an
Open window and then 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.
-
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:
provide 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
provides the names
if a line segment has more than one feature name, for example, Main
St. and State Highway 1010. 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 check box.
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 check box.
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 check box.
Click
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. For more information, see the following:

Click
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
