Not sure about the other APRS programs, but Xastir uses Shapefile
maps from NOAA, and there are only 6 or 8 files to download to get
them all.  Each archive will explode into 3 or more files.  As far
as I know there have never been hundreds of files to download in
order to get the weather alerts on your screen.

These files do represent thousands of different areas that can be
lit up, but there are hundreds of them in each Shapefile set.
