coordinates
Geographic position expressed through latitude, longitude, and altitude relative to their reference surfaces and lines.
Coordinates, or geocoordinates, are numerical values identifying the geographic position of a point on earth. The three numbers of any coordinate (altitude, latitude, and longitude) are measured with respect to sea level, the equator, and the Greenwich Line.
Latitude and longitude give angular position; altitude gives height relative to the sea-level reference used here. They are not three interchangeable distances from the earth's center.
A pinpoint location is one representative position for an object. A boundary uses multiple coordinate positions to describe an outline, while a map's zoom level controls the viewing scale.

6 sub-definitions-
altitude
The height of a point above or below the sea-level reference, expressed in meters with negative values below it. -
boundary
The outline of a region or the footprint of a structure, stored as a polygon of geographic coordinates. -
latitude
The distance of any point north or south of the equator, measured in degrees. -
longitude
The distance of any point east or west of the Greenwich line, measured in degrees. -
pinpoint location
The most central balancing point within a boundary or footprint outline. For buildings, use a 'city' field if coordinates are unknown or unclear. -
zoom level
The scale at which an object should ideally appear on a map for optimal viewing.
