To create your links, you will require a database where your links are stored and a set of maps you can base your links uppon.

The first thing you will need to do is to create or open a database.

Then you might be required to add topics, uppon which you can base your network links.

Once Dataset Properties has been completed, you can begin.

Adding Roads; Segments; Points; Intersections

Click on 'Linears & Points' at the top of the data tree and then click on add new road .

This will make a new road appear at the bottom of the data tree.

After filling in the 'General'-information you can continue by:

• Adding a new point / coppying an existing point / adding an intersection .

Once you are done adding points to your road, you can continue by:

• Adding another road

Or, if your road contains a large number of points:

• Adding a new segment

To maintain a good data overwiev and to prevent a data overload, one individual street should not comprise more than aproximatively 50 points. To increase the overview or if more points are required, a road can be sectioned into segments. Use this button to add segments.

Special Road Types: One Way, Interrupted and Isolated Roads

Iterrupted road: A road can be interrupted and continue on again under the same name at a later point. This might happen when two motorways merge and then split up again, but during the time they run together they carry the name of only one of the two motorways. This phenomenon can be modueled by ticking the box 'Interrups Road' in the 'Flags' menu of the points at the beginning and the end of the interruption.

In this example the points C and D stand at either end of an interruption. 'Interrupts Road' has been ticked in their 'Flags' menu. as a consequence, the icons to the left of their names have turned blue.
