[wxqc] MADIS Now feeding weatherundergound?

[Russ Chadwick]

Victor,

The place on the WU web site that I looked at last night had two places to
the right of the decimal point for lat/lon.  Perhaps there are other places
on their web site where this is different.  We try to locate CWOP stations
to an accuracy of 20 meters if possible.

Are you sure? When I view a station on weatherundergound, I see three
places to the right of the decimal (about 360 feet) and also degrees,
minutes, seconds (100 feet). I know I have a neighbor two doors down,
and I had no problem placing my station accurately enough to place it
squarely in my yard.

On the other hand, when I look at the stub for my station (MC6155) the
last digit is different (but not zero).
