graphic parameter generates an arc; Illustration 10 (f)
• Ellipse: The central point coordinate , half long axes,
half short axes of the ellipse and the other
fundamental graphic parameter generates an ellipse;
Illustration 10 (g)
• Ellipse arc: The central point coordinate , half long
axes, half short axes , start-stop angle of the ellipse
and the other fundamental graphic parameter
generates an ellipse arc , Illustration 10 (h);
• Dynamic line: From starting point coordinate and
destination coordinate and the other fundamental
graphic parameter generates the dynamic line,
Illustration 10 (i);

4 CONCLUSION
Object-based map symbol system model is popular with the
object-oriented thinking, according to the geometric properties
geographical entities, non-spatial attributes, symbols separate,
independent and not only constitutes a link between complex
and easy to understand the object, which is mapping, built the
integration of operations with unparalleled advantages.
