I draw wind arrows with different sizes and rotation using a function I defined in the postgres database. Problem with that is that when you zoom into the map, the arrows will grow too ... For my purpose that is no problem, but for you it might be.

Two attributes define the two-half-axis of the ellipse, another attributes define the rotation. These ellipses represent manhole points in the waste-water network. I know how to define the rotation of symbols - but is there a way to render ellipses based on the two half-axis? Are there any ideas? If not - I think I will create SVG symbols and classify the different sizes into different ellipse-symbols and apply the rotation.
