Basic to any science of mapping is a coordinate system. The scientific system used by the [[Imperium]] is based on rings of longitude, rays of latitude, and parsecs. By convention, rays of latitude and rings of longitude are measured from a starting point at {{WorldS|Reference|Core|0140}}, the world where the data from the First and Second Imperial [[Grand Survey]]s are stored. | Basic to any science of mapping is a coordinate system.

* The concentric ring passing through Reference/Capital is labeled the 10,000th ring, and is used as a baseline. Similarly, the ray of latitude extending from the center of the Galaxy through Reference/Capital is designated as the first ray. Measurement is in parsecs, counting in the [[trailing]] direction. Computation reveals that the circumference of the 10,000th ring (r=10,000) is 62,832 parsecs. Counting [[spinward]] uses a subtraction from 62,833, which is the equivalent of the zero baseline. | * The concentric ring passing through Reference/Capital is labeled the 10,000th ring, and is used as a baseline.

Imperial Science: This mapping system is highly ''Imperio-centric'', and other systems are used by other peoples and races outside the Imperium. This system has gained wide acceptance, however, among Imperium dominated client-states, human and otherwise. This mapping system breaks down and is prone to error beyond certain limits. It does serve admirably for a band approximately 400 parsecs wide at a longitude of 10,000 parsecs, which is a region precisely centered on the Imperium. | Imperial Science: This mapping system is highly ''Imperio-centric'', and other systems are used by other peoples and races outside the Imperium.
