I meant to post in this subforum originally. If the Earth is flat, why is the distance from my house to the nearest Walmart 1392 meters instead of the 1530 meters you would expect on flat earth with an azimuthal equidistant projection given the coordinates of my house and the nearest Walmart? D_f is the flat earth distance, D_fs is the "square" flat earth distance, and D_r is the round earth distance. https://www.desmos.com/calculator/0lftnuqmz0 Calculation for flat earth map distance: http://walter.bislins.ch/bloge/index.asp?page=Distances+on+Globe+and+Flat+Earth

sadly you have not given much to work with but here could be some solutions to your problem, if you do not actually know the true distance to your Walmart measure it, you could do this by measuring two streets that make a right angle leading from your house to the Walmart, you can do this by rolling a wheel with a dash on it down both streets, then multiply both by the wheels circumference. You then calculate the hypotenuse. After that you can make your comparisons to the flat earth distance model.

please reply when you have properly measured the distances
