Formal description of space.
OWL Full
spatial resource
Resource with 0 to 3 dimensions.
spatial point
Spatial resource without spatial dimension.
one-dimensional spatial resource
Spatial resource having 1 spatial dimension.
curve
one-dimensional spatial resource consisting of points extending in any direction.
line
Straight curve OR curve without curvature OR curve consisting of points extending in one direction.
two-dimensional spatial resource
Spatial resource having 2 spatial dimensions.
three-dimensional spatial resource
Spatial resource having 3 spatial dimensions.
polygon
Flat two-dimensional spatial resource with at least 3 straight lines joined to form a closed chain.
side
Straight line of a polygon.
quadrilateral
Polygon with four sides.
rectangle
Quadrilateral with four right angles.
length
Longer side of a rectangle.
width
Shorter side of a rectangle.
square
Rectangle with two adjacent sides having equal length OR regular quadrilateral.
surface
Two-dimensional boundary of a 3-dimensional spatial resource.
outer surface
Outer two-dimensional boundary of a 3-dimensional spatial resource.
centroid
Intersection of all straight lines dividing object X in 2-dimensional space into two parts of equal moment about the line. Informally, it is the "average" (arithmetic mean) of all points of X. The definition extends to any object X in n-dimensional space: its centroid is the intersection of all hyperplanes that divide X into two parts of equal moment.
X coordinate
X coordinate in a Cartesian coordinate system.
Y coordinate
Y coordinate in a Cartesian coordinate system.
Z coordinate
Z coordinate in a Cartesian coordinate system.
transferring
Bringing something from one place to another.
transfer
Something brought from one place to another.

Specifying a position of a spatial resource.
A position is described by 0 to n coordinates.
Specifying an X coordinate of a point in space.
