This may be listed somewhere, but what resolution (m/pixel) do the various zoom levels equate to? I'm guessing that zoom level 15 is about 2m/pixel. Is that about right?

Here are the formulas used by SBuilder:
Code: Select all
PixelsPerLatDeg = (2 ^ Zoom) * 256 / 180.0
PixelsPerMeter = PixelsPerLatDeg / 111330.0#
PixelsPerLonDeg = Math.Cos(LatDispCenter * PI / 180.0#) * PixelsPerLatDeg
