decimal places for the zoom level whilst still preserving accuracy sufficient to position the map within a few pixels. The relationship between zoom level, decimal places, and the accuracy with which the map can then be positioned in pixels is as follows: Zoom Decimals Accuracy (pixels) 1 0 1.42 2 0 2.84 3 1 0.57 4 1 1.14 5 1 2.28 6 2 0.46 7 2 0.91 8 2 1.82 9 3 0.36 10 3 0.73 11 3 1.46 12 4 0.29 13 4 0.58 14 4 1.17 15 5 0.23 16 5 0.47 17 5 0.93 18 6 0.19 So the worse case is at zoom 2 where accuracy is still within 3 pixels.
