In my initial post to Steve concerning this, I *did* mention that the
observation was made by an official weather observer.


Official weather observers take observations at official weather observing
stations. I'm an official weather observer, I take official weather
observations at KGRB. But I can't take them at WI78, where I keep my
airplane. That would require, for just the visibility observation alone, a
certified map provided by the NWS showing distance and direction to
specified visibility markers from the observation point.

Was your
accredited weather observer on
the ground at KEPM using such a map when he determined the visibility?


Yes he was. There are actually two maps, depending on whether the
observation is taken from the (so-called) terminal building, or from the
intersection of the taxiway and runway.
