[aprssig] regional APRS coordinators?

I don't know my Nevada geography, but have generated maps of the APRS 
infrastructure and mobile coverage over the past week for the general 
coordinates of the state of Nevada.  If you can figure out where Black 
Rock is, you should get a good idea of the existing infrastructure 
(digi/igate) and mobile coverage in the area and if the new digi will 
actually serve any purpose.

You'll find the set of maps at:


(0) is the least informative showing ALL traffic for the past week.
(2) shows ONLY IGate and Digi traffic and gives a pretty good idea of 
(3) shows dots for mobiles with large (Igate) and small (Digi) dots from (2)
(4) is the same as (3) using large/small green dots for the Igate/Digis

These images are 768 wide by 1024 tall so if you don't run a large 
resolution monitor, you'll need to zoom in and pan around with your 
browser to see the details.

Let me know if this helps and where Black Rock is (NE, SW or which 
existing IGate it is near).
