gml:GridCoverage

A gml:GriddedCoverage is a discrete point coverage in which the domain set is a geometric grid of points.
Note that this is the same as the gml:MultiPointCoverage except that we have a gml:Grid to describe the domain.
The simple gridded coverage is not geometrically referenced and hence no geometric positions are assignable to the points in the grid. Such geometric positioning is introduced in the gml:RectifiedGridCoverage.
