Hey there,<br>
<br>
I have my own project for the visualization of data points and I use marble. My problem is that I want to draw circles / ellipses, whose radius is dependent on geographical distance (meters/kilometer).<br>
I know how to generally draw in marble - thanks to your tutorials!<br>
However, QPainters draw-methods bases on pixlesize.<br>
<br>
The problem is that i have no idea how to<br>
convert a geographical size into pixlesize for using QPainters drawmethods<br>
or<br>
find a method that draws a circle / ellipse, whose radius corresponds to a geographical distance. (for example the lenght of a geodatalinestring)<br>
<br>
I would thank for any advice or idea.<br>
<br>
Tom<br>
