A number of tenants are housed in the building with a mix of enterprises companies and data center providers. If an enterprise moves out, the space is absorbed by data center providers expanding in the building. Data Center providers include Equinix, DataBank, zColo, Cologix, Chewy, and Flexential. [15] Wade College [16] is also in the building.
The North American Datum of 1927 (NAD 27) was based on surveys of the entire continent from a common reference point that was chosen in 1901, because it was as near the center of the contiguous United States as could be calculated: It was based on a triangulation station at the junction of the transcontinental triangulation arc of 1899 on the ...
A geodetic datum or geodetic system (also: geodetic reference datum, geodetic reference system, or geodetic reference frame, or terrestrial reference frame) is a global datum reference or reference frame for unambiguously representing the position of locations on Earth by means of either geodetic coordinates (and related vertical coordinates) or geocentric coordinates.

In three-dimensional space, if one coordinate is held constant and the other two are allowed to vary, then the resulting surface is called a coordinate surface. For example, the coordinate surfaces obtained by holding ρ constant in the spherical coordinate system are the spheres with center at the origin. In three-dimensional space the ...
The coordinate origin of WGS 84 is meant to be located at the Earth's center of mass; the uncertainty is believed to be less than 2 cm. [7] Handheld GPS receiver at the Royal Observatory, Greenwich, indicating that the Greenwich meridian is 0.089 arcminutes (or 5.34 arcseconds) west of the WGS 84 datum (the IERS Reference Meridian)
Data centers could use up to 9% of total electricity generated in the United States by the end of the decade, more than doubling their current consumption, as technology companies pour funds into ...
A Cartesian coordinate system in two dimensions (also called a rectangular coordinate system or an orthogonal coordinate system [8]) is defined by an ordered pair of perpendicular lines (axes), a single unit of length for both axes, and an orientation for each axis. The point where the axes meet is taken as the origin for both, thus turning ...
Thus the state plane coordinate system is still useful. Originally, the state plane coordinate systems were based on the North American Datum of 1927 (NAD27). Later, the more accurate North American Datum of 1983 (NAD83) became the standard (a geodetic datum is the way a coordinate system is linked to the physical Earth). More recently there ...
