Earth's Geometrization

 are the locations on Earth given a specific designation and evaluation by the Combine to house its workforce.

Earth
Earth, designated CMB-314, is one of the planets under the Combine's domain.

Sector
The Sectors are continent-sized regions that encompass more than 2 cities and the outlying regions in-between. The Overwatch Transhuman Arm and Overwatch A.I. are based at a Sector-level. The Sector Administration typically operates out of the largest city in the Sector.

City
Cities, or Urban Locations (abbreviated: URB-LOC), are metropolitan areas that act as self-governing city states. Cities report to the Sector Administration. The majority of the remaining human population is herded within these Cities, with some notable ones being:


 * City 17, located in former Sofia, Bulgaria (capital of Sector 17)
 * City 24, located in former Geneva, Switzerland (capital of Sector 12)
 * City 2, located in former New York, USA

Indent
Districts, officially known as Indents, are the subdivided regions within a city, similar to the 'boroughs' of the old world. Citizens are denied free movement between districts - they are the individual population centres within cities.

Symbols
Some Overwatch forces don insignia that detail their assigned Indexed Locations.

For example, c̄17:i4 refers to City 17 District 4, c̄24:i1 refers to City 24 District 1, c̄08:i5 refers to City 8 District 5, and so forth.
