Hello,

I need to get a variable circle around my current position depending on the height of the local gps.

<vehicle name="Local GPS" ....
<cursor w="600" h="600">
<itemgra>
<circle color="#ff0000" radius="500" width="10">
<coord x="0" y="0"/>
</circle>

I need to get the radius="500" to be changed on the fly depending of the height or scale.

I try to visualize the ideal reception mark on a map depending on the height of a plane
We need it for television broadcasting of cycle races

Somebody have ideas ?

Thank-you

I did read you the first time already, but have no idea. Apart from drawing the circle, I don't know of a reliable source for elevation data within navit. GPS is +-50m in that direction.
