Abstract: A map or globe is provided with a transparent thin covering capable of conducting electricity. The transparent thin covering envelopes the globe or overlies the map. An electrical resistance measuring means would be employed to determine a measure of electrical resistance between any two points on the map or globe. The electrical resistance measuring means would include a first probe and a second probe. The first probe would be placed on a first location on the map or globe and the second probe would be placed on a second location on the map or globe. A measure of electrical resistance will be generated by the electrical resistance measuring means reflecting the resistance of the conductive thin covering between the first location and the second location. This electrical resistance is proportionally related to the distance separating the two points on the map or globe.
