seen on the whole display, not just what is inside the range circle.
It also fetches 4 zoom layers higher than what you are looking at, in
order to get the higher zoom levels. If you want even higher detail,
you'll need to zoom in and wander around the area again.
A small area like you describe (if it's also 200 miles wide) would
take about 2 or 3 minutes to fetch.
> Any tips on prefetching maps appreciated.Look at the area you are interested in, wait for the tiles to fetch,
zoom in, scroll back and forth across the area of interest, waiting
for the tiles to download as you go. Rinse and repeat until you have
all tiles to the desired zoom level.
