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.
