Q. What is maximum magnification percentage?

A. “maximum magnification percentage” is a detail level of the clipped map.

DecaMaps draws a detailed map that you select an area of the map.
The area you select is wider; the detail level of the clipped map is decreasing.

*When you enlarge the map to maximum, the maximum magnification percentage gets to 100%.
