A facilitated event at which users of a particular regional solution are invited to share ideas on how to improve the solution, including but not limited to data content, access and custodial responsibilities. Through these events, MetroGIS identifies ways to ensure that solutions maintain their relevance with changing user needs, and leverage resources that were not available when the solution was implemented.

Internal parameters of positioning systems indicative of the level of performance achieved.

One-dimensional geometric primitive representing extent in time.

Duration of one cycle.

Projection centre.

Point located in three dimensions through which all rays between object points and image points appear to pass geometrically.

Use of aerial photographs to produce planimetric and topographic maps of the earth`s surface and of features of the built environment. Effective photogrammetry makes use of ground control by which aerial photographs are carefully compared and registered to the locations and characteristics of features identified in ground-level surveys.

Quantity used for the quantitative description of physical phenomena.

General appearance of an object or terrain, without reference to its underlying or scientific characteristics.
