SPLAT! is able to plot coverage of multiple transmitter sites, with each plot a different colour. Overlap areas are in yet different colours again.

Dick,

I can wholeheartedly endorse the us of SPLAT as Alex Carver has suggested.

Take a serious look at the SPLAT web page and then get back to us via the
reflector here with your questions.  You are most likely not the only one
looking for this type of information.

I have SPLAT loaded on my laptop that is running "ubuntu 8.04-LTS" for the
operating system.  I am certain the group can assist you.  SPLAT has no
problem outputing "kml" files to use with Google Earth and or Xastir.

We would need to know where you are and the locations of the digipeaters
thgat you are wanting to get a coverage map of.

I'm interested in plotting digipeater coverage, and this message can be
viewed as a feature request or a request to know where it has been
implemented.

Our ARES and RACES groups often support bicycle rides, runs, and relay
races that take us out into the county far from digipeaters and often into
hilly terrain. To fill gaps in coverage we deploy fill-in digipeaters. If we
could plot coverage of digipeaters, we could more easily judge our fill-in
digi's and possibly move them to better locations.

Coverage could be constructed from incoming packets.  The first digi on
the packet path is the first digipeater to pick up the packet, and the
packet location provides the coordinates of a place that is covered by the
digipeater.

Coverage could be plotted using convex polygons that enclose the set of
pick-up points for each digipeater.  Polygons for different digi's could be
colored differently. And, points of pick-up locations could be plotted using
the same color as the polygon, jittered slightly to make visible instances
in which two digi's pick up the same packet. Ideally,  locations would be
stored over some period of time, rather than working with only the most
recent station reports.

Does anyone know where this idea has been implemented?  Is the xastir crew
interested in implementing it?

Thanks,

Dick Repasky
