@mightymoe It turns out that HSM stands for Hunting Shack Munitions. It's in Stevensville.

Hi, Moe. Cool picture; glad that math has some successes. Off topic, but I ordered some HSM ammo and got it today. I didn't know that HSM is in Montan...

@dave-o Well, it does take quite a bit of higher mathematics to flatten that curved surface. Sometimes simple is difficult to achieve.

@peter-lothian These may help, but not complete and exhaustive. There's a rich history of legislation in the formation of this park. One requiremen...

@dave-o Hmmm. So why do we have all of those state planes and that Transverse Mercator stuff?

@dave-o Ptolemy's complicated model of the universe worked, but it was replaced by the simpler model of Copernicus. And flat is way simpler than cu...

@norm Yep.

@thebionicman Understood. Being sticklers on rounding grading is one way that physics teachers get students' attention. Measurement accuracy and ...

Just maddening. Where did I fail? (Don't answer that!) It's just fundamental that a measurement like, say, 21.50 feet, represents an exact measureme...

But if Ireland invaded Antartica, each penguin would have to fight off only something less than 1/3 million Irish persons. Understanding fractions is ...

Take three of the mis-stamped caps to Ebay. Hawk them as rare, mis-stamped survey caps from (date and place.) Beautifully finished and in excellent co...

@tnt Those walls perpendicular to the coast are called groins and they have a very different purpose than seawalls. They're used to prevent sand fr...

That's a nice piece of work, Scott. You've always had my endorsement (surely not worth much) for fine geodetic work, but maybe one from CjatGPT is wor...

Correction: 1.0148794/2.54/12 = 0.03286 International ft/mile should be 1.0148794/2.54/12 = 0.033286 International ft/mile

Correction: 1.0148794/2.54/12 = 0.03286 International ft/mile should be 1.0148794/2.54/12 = 0.033286 International ft/mile

@sluggo Kinda right, but by using 0.008, you've converted your answer from millimeters to meters. 8*sqrt(1.609344) = 10.148794 mm. (1 mile is 1.6...

Be careful here. Are the coordinates that you gave us UTM or local coordinates? If the coordinates are UTM and the bearing and distance are on a local...

"But the advantage with the DOT method is that you can easily import-export data into your programs. All you need to do is have the one scale factor a...

Learning the underlying math is relatively easy when one has a lot of free time, but applying this stuff in the field under time and terrain pressures...
