Blockunit

In the Kingdom of Quotro a blockunit is the elemental geographic information unit. Every settlement, island, district, borough and metropolitan area is built from one or more blockunits. As of May 2020, the entire Kingdom is divided into 302 blockunits. 
Blockunits were created in October 2019 to make geographic information much easier to keep track of. Information only has to be stored at the blockunit level and information about other areas is automatically calculated by summing groups of blockunits.
== Attributes ==
Each blockunit has eight attributes, and each attribute can only have one value:
# A unique four digit identification number (e.g. 1001)
# A description (e.g. "Capital Gate")
# The district the area sits in (e.g. "Stephens")
# The borough the area is a part of (e.g. "Upper Hammerhead")
# The settlement, or "Unaffiliated" if the area is not part of a settlement (e.g. "Port Thomas City")
# The landmass on which the blockunit rests (e.g. "Central Is.")
# The building count within the area (e.g. 36)
# The land area of the blockunit in m² (e.g. 9,506)
If a situation develops where an attribute would require more than one value (for example if a new landmass is carved off an old one) then a new blockunit must be created.
