GWC 3D

BoCA has developed a Garden world Classification chart that determines the level of compatibility to NiOx breathers - Carbon Based.

This chart system is not used as much anymore and has been replaced by the BaPhy Union Member Compatibility Classification System that is used for all Celestial RealEstate, but it is still a guide for Colonists.

A gardenworld 3 D is on the "Frigid scale", placing it between 2 D and 4D.

GWC 3 D is a cold world with temperatures globally not rising above 10 on the C scale.

It may also have one or more of these D type characteristics:
 * Hostile lifeforms: Native lifeforms exist that poses a lethal threat to an unprotected human / humanoid
 * Tectonic activity: Severe tectonic activity causing earthquakes, lava streams or volcanic eruptions
 * Climate: Planet average temperatures do not fall below -30°C and do not exceed 50°C (Planet average local regions may exceed these values)
 * Weather: Some extreme weather conditions exist. Axial tilt moderate
 * Land/Water: Land surface is between 45% and 331/3% of water surface
 * Water: Ample sources of Fresh water
 * Atmosphere: Standard Humanoid / human can breathe atmosphere without any ill effects.
 * Gravitation: Not less than 0.75g and no more than 2g
 * Aerosols: Some harmful pollen, microbes or pathogens
 * Natural Resources: Medium resources - compatible food sources, fertile soil, common minerals and metals present
 * Pollution: Little to no pollution of any kind, No harmful radiation
 * Lux: Night and Day cycle, local star in within distance "Goldilocks Zone"
 * Civ: previous civilization may have existed
