Why was the placement of the prime meridian considered logical?

Answer 1

The placement of the prime meridian at Greenwich, England, was considered logical due to its historical significance as a major center for maritime navigation and astronomy in the 19th century. The Greenwich Observatory was a key reference point for sailors, and establishing the prime meridian there provided a standardized location for measuring longitude. This choice also facilitated international cooperation and communication, as many countries were already using Greenwich Mean Time (GMT) as a time standard. Ultimately, the decision was made at the International Meridian Conference in 1884, where it was agreed to adopt Greenwich as the global zero longitude reference.
