The Pundits (spies for the Indian Political Service) were trained to count standardized paces for cartographic purposes. Basically an adaptation of a military cadence. How much can be done with this?

A foot column can by this means means measure it's progress down a route in precise terms. A vehicle can have a device to count wheel rotations. I haven't the foggiest idea how one will do this with animals especially if they are in harness. If they are pulling a vehicle though, rotations of the wheel can be counted in the summer. There is probably some ingenious device that can be rigged for a sleigh.

These are rather primitive methods but useful. Is there a dead reckoning app that will render this obsolete?
