History[]
By the mid-21st Century, the stellar neighborhood of Old Earth had been completely surveyed and mapped, due in large part to the launch of numerous orbital satellites making use of such equipment as wide-field infrared, nanometer spectral, gravitational microlensing, and polarimetric telescopes and sensors. Extensive databases were filled with the information, and these databases accompanied the colonists to the new planets. Once there, using ground-based equipment primarily, the “planetary surveys” were updated and augmented to reflect the new constellations and stellar configurations as observed from the surface. In turn, these “star maps” were utilized by the colonists for a variety of pursuits, from commercial fishing to predictive agriculture to planning the positioning of orbital satellites around this new planet.
Game Information[]
Planetary Survey is a Tier 0 Secondary Tech that can be researched from Habitation.
Planetary Survey gives the final brush in the initial adaptation to the new world. It establishes a reliable GPS system, together with a set of additional orientation techniques which grant land units mastery of the seas of the new planet. They gain the Embarkation ability, allowing them to cross water, and the Worker unit gains the ability to construct the Work Barge on water resources.

Rising Tide[]
In the Beyond Earth expansion, Rising Tide, units automatically have the embarkation ability. Instead, planetary survey allows for floating cities to move from coastal tiles to deep ocean tiles.
