Here, of course, I’m specifying the bearing from map north, marked by the little direction arrow over the encircled ‘66’ on the left of the map. Does …
Operationally, if starting out from an actual on-the-ground bearing/range (degrees/miles) coordinate pair and wanting to determine where we would find…
What your calculations show us here is that if the Phillips 66 were correctly aligned on true north and if the scale were 6.4 miles to the inch, then …
Hi @Marclean. Yeah, it looks like what you’re doing there is reading the scale marks the wrong way around. The 0, 1, 2, 4, 6, 8 are the miles alread…
For context:
To pursue more precise values for the scaling and northing errors of the Phillips 66, we can substitute for our previous method—one which used a minim…
But are you, though? I’m asking, because the location you have marked looks awfully close to what you would get if you used a modern accurate mappin…
Actually, I was using an old somewhat rough and ready map overlay. Constructing the same much more precisely, I do find that your candidate just creep…
Yes, it is easy to fall into misunderstandings over this, @Northkey. However, thankfully on this occasion my reading is intended to be precisely the s…
Hi Northkey. Welcome. Can you post an image showing where you understand your proposed solution to point to. Certainly, in taking the Phillips 66 to…

But, hold on. Have we not just taken our control analysis too far in the reverse direction? Is it really as damning to our original control analysis a…
