Spherical coordinate system

A spherical coordinate system is a system of coordinates used to specify the positions of objects in three-dimensional space. It consists of three axes, each of which is perpendicular to the other two. The axes intersect at a point called the origin, and the positions of objects are specified by their distance from the origin, and the angles they make with the axes.

Supply Side Platform (SSP)

A platform that allows publishers to manage the inventory of ad space on their websites and mobile applications, and to set prices for that inventory.

Temporal reference system

A temporal reference system is a system of coordinates used to specify the positions of objects in time. It consists of one or more axes, each of which represents a different time scale. The positions of objects are specified by their distance from the origin, and the time at which they occur.

Temporal thing

A temporal thing is an object that exists in time. It has a definite beginning and end, and exists for a specific period of time.

The Data Management Association (DAMA)

DAMA is an international professional association for data management professionals. DAMA provides guidance on data management best practices and promotes the exchange of knowledge and experience among data management practitioners.

Thematic map

A thematic map is a map that shows the distribution of a particular theme, such as population density, climate, or land use.

Topographic map

A topographic map is a map that shows the relief of an area, that is, the shape of the land surface. It is usually shown with contour lines, which are lines of equal elevation.

Topography

Topography is the study of the shape of the land surface. It includes the measurement of the elevation of the land, and the identification of landforms such as mountains, valleys, and plains.

Topology

Topology is the study of the properties of space that are invariant under continuous deformations, such as stretching, twisting, and crumpling. It is concerned with the properties of space that are preserved under such deformations.

Triangulated irregular network

A triangulated irregular network is a data structure used to represent a three-dimensional surface. It consists of a set of points, called nodes, and a set of triangles, which are defined by the nodes. The triangles are used to approximate the surface, and the nodes are used to store the data values.
