Europe is a large peninsula conventionally considered a continent in its own right because of its great physical size and the weight of its history and traditions. Europe is also considered a subcontinent of Eurasia and it is located enti ...

The grid is designated as Grid_ETRS89-LAEA5210. For identification of an individual resolution level, the name is extended by identification of cell size in metres (example: _100K).

(x=0, y=0). Grid points of grids based on ETRS89-LAEA must coincide with grid points at Grid_ETRS89-LAEA5210.
The grid is defined as hierarchical one in metric coordinates in power of 10.
The resolution of the grid is 1m, 10m, 100m, 1000m, 10,000m, 100,000m.
The grid orientation is south-north, west-east.
The reference point of the grid cell for grids based on ETRS89-LAEA is the lower left corner of the grid cell.
