Those with superior mapping skills please discuss important issues with me here.

Give me a few minutes to digest all the maps I'm getting.

Heh heh heh... there may be enough "nosies" gathered round to keep the unfriendlies from seeing the map table.
Jusssst kidding - you work on what you need to work on and we "nosies" will just wait with bated breath. Good luck!

NavyChief: I don't know what you're up to, but if your previous work is any indication, it'll be good. You done the right thing by keeping it secret.
Whatever mission you're on, Godspeed !!! |

Okay. This is probably easier to do this in open forum
All you guys are great but I can't keep track of all the PMs.
Can someone/anyone/everyone plot the following for me please.
(a) VQ 35 94
(b) VQ 64 78
(c) WQ 798 666
Now. Distance between (c) and (b). Distance between (b) and (a). Distance between (c) and (a).
I know it's cryptic but you guys know me by now. I'll spill when the time is right
As you can see, I suck at mapping. I just want as close as possible (good enough for government work).

Chief
Its been a while since I worked with the Military Grid but ...
I think the following should work
< Someone will correct me if I am wrong >
# Python script used
#
# locations in meters from VQ 00
# expressed as 2D vectors
>>> A = [35000, 94000] # VQ 35 94
>>> B = [64000, 78000] # VQ 64 78
>>> C = [179800, 66600] # WQ 798 666
# compute differance vectors
# Vec2 = [ deltaX, deltaY ]
>>> cb = [ C[0]-B[0], C[1]-B[1] ]
>>> ba = [ B[0]-A[0], B[1]-A[1] ]
>>> ca = [ C[0]-A[0], C[1]-A[1] ]
# compute distances in meters
# lengthVec2 = sqrt(x**2 + y**2)
>>> CB = sqrt(cb[0]*cb[0] + cb[1]*cb[1])
>>> BA = sqrt(ba[0]*ba[0] + ba[1]*ba[1])
>>> CA = sqrt(ca[0]*ca[0] + ca[1]*ca[1])
# print distances in kilometers
>>> print "CB = %.3f km"%(CB/1000)
CB = 116.360 km
>>> print "BA = %.3f km"%(BA/1000)
BA = 33.121 km
>>> print "CA = %.3f km"%(CA/1000)
CA = 147.370 km |

Not a typo but it could easily be a mistake.
Note that in my computation these coordinates are all
relative to VQ 00 and WQ 00 is IIRC 100 km east of VQ 00
It has been close to 40 years since I last used a Military Grid
though so I posted the method of obtaining my results
so that others can easily double check them:-) |

Chief,
Being an Army Aviator, I never get lost; I just get misoriented.
If I may be of help, please advise. Also an Information Systems geek in my current life if that helps any.
Also have access to maps in SE Asia. See pointer on my Web Site.
Cheers,
Lost in Wisconsin

......... Revised Chart presented in a later post ........
Distance A to B: Approx 33 km
Distance B to C: Approx 90 km {Air Route}
Distance B to C: Approx 150 km (via sea around Ca Mau)
Distance C to A: A-B plus B-C ... your choice of route
Be it far from me to question a spook chief's reading of
co-ordinates from message traffic ... how-some-ever
Those sure are widely separated locations. (esp B to C)
