Square-Mile Mapper

Double-click map to re-center square. Drag red square to new position.

Use "Draw over border" option for square's border to be centered on perimeter (thus, half of red line will overlap the selected area). Use "Draw outside border" option if you want the selected area to be snuggly inside the red perimeter.
