Abstract globe, to show the geographical coordinates of locations by longitude and latitude, has an equator disk and parallel latitude disks together with longitude disks where their intersection shows locations
The abstract globe (10), to show the geographical location of a particular place, has at least one latitude disk (1) as the equator, together with spaced and parallel latitude disks (6,7). The globe also carries at least one longitude disk (23,45). The disks are arranged so that an intersection (20) between the latitude and longitude disks marks the required location.
