<div dir="ltr">As a followup to this question, I'm trying to wrap my head around how to translate actual distances to what is shown on the map. For example, if I wanted to create a feature with a radius of 20 kilometers, how do I specify the radius for the feature based on the map's resolution and scale. I'm not quite clear on how feature radii relate to map resolution and scale.<br>

<div dir="ltr">I was wondering if it is possible to dynamically resize a point
based on the zoom level of the map.<br><br>With the example at <a href="http://www.openlayers.org/dev/examples/styles-unique.html" target="_blank">http://www.openlayers.org/dev/examples/styles-unique.html</a>,
can we make the points change their radius as we zoom in? I'd like to keep
the circles the same relative size to the underlying map
layer.<br><br>Thanks,<br><br>- Chris<br></div></div></div></div>
