You may experience a performance issue if you try to export a map that
covers a very large area. To improve performance, decrease the size of the
map. If the map does not cover the area you need, export several smaller
maps until they cover the entire area you need.
Grid Size Comparisons
When you use the Handheld Export tab to export maps, you can choose a grid size.
A grid of the same size gets progressively larger in coverage (square area) the closer
it is to the equator. This is because the grid system is based on the
latitude/longitude coordinate system.
60 seconds = 1 minute
60 minutes = 1 degree
A 1.5 degree grid = 9 30 minute grids, 324 5 minute grids, 8,100 1 minute grids, or
202,500 12 second grids.
A 30 minute grid = 36 5 minute grids, 900 1 minute grids, or 22,500 12 second
grids.
A 5 minute grid = 25 1 minute grids or 625 12 second grids.
A 1 minute grid = 25 12 second grids.
