Fantastic effort!

But without plotting the PHG circle, just seeing green stars
says nothing about the network or communication coverage.  A
digi with a height of 5000 feet HAAT covers 10,000 times more
area than a digi at 50 feet.  And there are a lot of 50' digis.

Can you add PHG circles to these plots?   Then it is easy to see
the valuable digipeaters versus the fill-ins.  I think there is
an add-on to Uiview for plotting this fundamental APRS PHG data.

Besides where your station is, there is no other single most
important parameter to VHF communications than antenna height.
This was fundamental to APRS, and should not have been left out
of Uiview.
