Continuous coverage which uses a systematic tessellation based on a regular rectified quadrilateral grid to cover its domain, where the elevation property value is usually known...

A volume of rock with distinct characteristics. Includes both formal units (i.e. formally adopted and named in an official lexicon) and informal units (i.e. named but not...

This layer only applies to GeophStation spatial object types whose value from the StationTypeValue code list is seismologicalStation

Brittle to ductile style structures along which displacement has occurred. These range from from a simple, single 'planar' brittle or ductile surface to a fault system...

Area of the Earth's surface where the elevation model is unknown because of missing input data. This area shall be excluded from a DEM.

Orthoimage coverage

Elevation TIN

Point spatial object which describes the elevation of an Earth's surface at a specific location. It provides a single elevation property value.

Linear spatial object composed of a set of adjoining locations characterized by having the same elevation property value. It describes, together with other contour lines present...

Abstract type identifying both the contributing area and the acquisition time of one or several input images used to generate a mosaicked orthoimage coverage.

Delimitation of an area of the Earth's surface where an isolated part of the elevation model exists. Its outside surroundings have no elevation information.

A line of a critical nature which describes the shape of an elevation surface and indicates a discontinuity in the slope of the surface (i.e. an abrupt change in gradient)....

A vector representation for Land Cover data.
