United Mapping, also known as United Mapping - Headquarters, is a mapping Discord Server that serves as an interserver organization tasked with eliminating toxicity, and organizing interserver events. It was created on November 29, 2018. It is owned by Ares, and co-owned by Vex and JanuszKońwin. It was also previously co-owned by Bashkir, but he lost the UM elections.
UM currently has a total of 15 member servers.
United Mapping has been criticized by some for allegedly copying the Mapperdonian Station, yet Ares has denied this and has expressed interest in cooperating with the Station. Some others, such as Axis Mapper, berate United Mapping for attempting to "taking control of all mapping communities".
