Digitize a baseline interactively. A circle is attached to the mouse pointer. Points must be added where the coastline or low-water line meets the circumference of the circle, and the circle must not cross the coastline.
The circle simulates running a wagon wheel over the coastline or low water line. The radius of the wheel equals the value of the limit line. Points that are touched by the wheel are called contributing points because they contribute to the limit line. A large wheel touches fewer points than a small wheel, therefore baselines created using large radiuses will be smoother than those using smaller radiuses.
This is similar to the Wagon Wheel Filter command except that it is interactive.

Procedure
1. Choose the Interactive Baseline command.
The Interactive Baseline dialog box is displayed.
2. Select a feature acronym.
3. Set any required attributes.
4. Enter a radius.
5. Click OK.
6. Click at the start point of the new line.
7. Press and hold the left mouse button and move the mouse.
A circle is attached to the mouse pointer. This circle is anchored at the point you just entered; it will “slide” around as the pointer moves. If the circle disappears, the pointer has moved outside the limit indicated by the circle.
8. Release the mouse button to place the next point.
9. Repeat until the entire line has been added.
10. Right-click and select Line Digitizer > End Line.
The baseline is drawn.
