Statistical Grid - Spatial object type

Definition: A grid composed of statistical cells.

Description: Such grid is associated with an upper grid, that has a bigger resolution, and a lower grid that has a lower resolution. Some statistical grids are organised into a hierarchy of grids with different resolutions. The cells composing two linked grids have to satisfy some topological constraints: each cell of the upper grid should be the aggregation of cells of the lower grid.EXAMPLE The hierarchical structure is a quadtree if the grids are composed of quadrilateral cells and each cell is composed of less than four cells of the lower level.

Attributes

Definition: The position of the origin point of the grid in the specified coordinate reference system (if defined).

Description: The origin point is the lower left grid point.

Multiplicity: 0...1

Valuetype: DirectPosition

Definition: The grid width, in cell number (if defined).

Multiplicity: 0...1

Valuetype: Integer

Definition: The grid height, in cell number (if defined).

Multiplicity: 0...1

Valuetype: Integer

Definition: External object identifier of the spatial object.

Description: An external object identifier is a unique object identifier published by the responsible body, which may be used by external applications to reference the spatial object. The identifier is an identifier of the spatial object, not an identifier of the real-world phenomenon.

Multiplicity: 1

Valuetype: Identifier

Definition: The EPSG code to identify the grid Coordinate Referencing System.

Description: This information is relevant only if all cells of the grid have the same CRS.

Multiplicity: 0...1

Valuetype: Integer

Definition: The grid resolution.

Description: This information is relevant only if all cells of the grid have the same resolution.

Constraints

Type Invariant

Status Approved

Note /* If the coordinate reference system is a projected one, the resolution shall be a length. Otherwise, it shall be an angle. */
