The course I normally play was mapped by a Sky Golf employee. Our pro
said that he was wearing a "big backpack unit" with a "big antenna".
I'm guessing that his measurements were much more accurate than would be
done with a simple hand held GPS.
Yup, that would be a DGPS receiver. Your description sounds like the one
we use. I wonder where he got the DGPS signal.
The downside of this was that the guy went out by himself and had never
seen the course before. I'm guessing that once you have course mapping
experience you'll do fine. However, there may be some "local landmarks"
that may be missed.
True. And don't forget that, even though the map inside the SG may be
perfectly accurate, we are still referencing it via an instrument with
lower accuracy. IOW, while the SkyCourse may have a hole correctly mapped
with exactly, say, 100 yards between points X and Y, our instrument will
never let us know with the same accuracy that we are standing at either of
those points.
There are 2 courses in the north part of the county that are, I believe,
within the range of the DGPS signal from Alabama A&M University (where we
conduct some of our ag experiments). One day I'll have to take the SG up
there and see if the DGPS signal has any noticeable effect on my game.
I'm betting it won't. :-)
