Here's my internal diagnostics along with the raw packet from aprs.fi:

4823.10N 11530.30W
So, the object starts at 48 23.10N 115 33.90W
Line type 'j' (Green Solid)
Object type '0' (Closed Polygon) Interestingly the points close the
polygon anyway and I gather it's NOT supposed to be filled?
Scale 'I' or 73 which is 0.01 units per increment
NH = 78/72 or 0/-6 increments which I thought was 48 23.10N 115 30.30W
which is indeed EAST of the start because of the negative?
JN = 74/78 or -4/0 or 48 20.70N 115 33.90W (Negative N/S is south, zero
E/W offset)
PT = 80/84 or 2/6 or 48 24.30N 115 37.50W (Now North of the start, and 6
puts us further WEST of the start?)
RN = 82/78 or 4/0 or 48 25.50N 115 33.90W (Still North of the start, but
zero E/W offset)
NH = Same as first
So, the N/S offsets are supposed to be E/W in-line with the object
itself (2nd and 4th points). Both images agree with that.
The first point is N/S in-line and EAST of the object...Yep, my debug
has the right value, but my plotting is worng. Copy/Paste error between
the debug and the actual point calculation!
The third point is supposed to be NW of the object, but mine is NE on
the plot even though my debug has the right coordinates. Funny how a
little +/- swap will do that to an image!
Thanks for the screen cap of what it should be Tom! And for the bandwidth!

I don't know if this will come through, but is this what the MSOFFWKYA
flood warning should look like?

Looks like you might have a sign error in decoding. When I view the
object in Xastir, it looks almost like a mirror image of what you show there.
Take a look at http://www.swcp.com/~russo/imgs/MSOFFWKYA.png for what
it looks like here.

It sounds like yourself, Gerry, Alex, and I are all interested in
doing something about this. Perhaps Tom and Lynn as well. We happen
to have flood alerts happening in my county right now.
