Walking/Hiking Answers
Got an answer to the following Walking/Hiking question?
Real Distance Vs Horizontal Component
Maybe you can answer a walking GPS question that has always bugged me. If you walk 1 km up a 45 degree slope, will the GPS register that you have walked 1 km, or will it only register the horizontal component of the distance, i.e. 1/√2 km, which is 0.71 km. Presumably it would register your vertical ascent correctly at 0.71 km, but I want to know if these devices are smart enough to take into account at every stage in a walk, up or down, how steep the slope is. Of course the ultimate example would be if you were to climb 1 km up a vertical rock face (unlikely I know), would it register that you had travelled 1 km or 0 km? Any ideas?
