Hey, all, working on a project that involves users identifying a space through a
map interface (on mobile, using Yahoo! Blueprint). I went through and calculated
a reasonable search radius (for feeding into Y! local) by using the scale on a
map at each zoom level. I went to use it today, and noticed that the scale on
the maps are now different (rendering the previous calculations useless).

Is there a programmatic way to determine the scale of the map? With that, I
could figure out (combined with the size of the map) a search radius.

Thanks in advance!

Best,
