If a map contains pushpins/waypoints that span only a couple of miles, the map should be zoomed way in and show a lot of detail. If the pushpins/waypoints instead cover vast areas, such as hundreds or even thousands of miles, it should be zoomed way out.That's clear. My question is: is there a general guideline for mapping (no pun intended) Bing Maps zoom levels to a particular number of miles that separate the furthest apart points? e.g., is there some chart that has something like:Zoom level N shows 2 square milesZoom level N shows 5 square milesetc.?
Is there a rule of thumb for what a bing map's zoom setting should be based on how many miles you want to display?
