Hi Greg I just entered the pole for a gee-wiz kind of exercise. To my surprise, it returned zero, so I tried a location close to the pole. That returned non-zero, indicating that the software has some sort of bug. Since I have no way to verify any other result it may present to me, I will distrust the data. How many other lat long locations give 'bad' data? How would I know? Should NOAA fix this? Certainly. How silly of them to permit an entry which provides erroneous results. Do navigators depend exclusively on a compass within 366 feet of the north pole? I sure hope not...

Does NOAA need to correct this since it is only 366 ft from the pole?
