European grid

The European grid is a proposed, multipurpose Pan-European mapping standard.[1] It is based on the ETRS89 Lambert Azimuthal Equal-Area projection coordinate reference system, with the centre of the projection at the point 52° N, 10° E and false easting: x0 = 4321000 m, false northing: y0 = 3210000 m (CRS identifier in Inspire: ETRS89-LAEA). [2]

This article is about a map system. For the computer network, see European Grid Infrastructure.

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).

The origin of Grid_ETRS89-LAEA5210 coincides with the false origin of the ETRS89-LAEA coordinate reference system (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.

Norms
gollark: Probably.
gollark: Oh, and, additionally (I thought of and/or remembered this now), knowing your actions are monitored is likely to change your behavior too, and make you less likely to do controversial things, which is not very good.
gollark: i.e. demonstrate that they can actually function well, enforce the law reasonably, have reasonable laws *to* enforce in the first place, with available resources/data, **before** invading everyone's privacy with the insistence that they will totally make everyone safer.
gollark: Reduced privacy in return for more safety and stuff might be better if governments had a track record of, well, actually doing that sort of thing effectively.
gollark: I... see.
