Statistical grid cell
Unit for dissemination or use of statistical information that is represented as a grid cell.
-- Description --
A statistical grid cell is associated with:
- the unique statistical grid cell of its upper level (if any) it is covered by,
- the statistical grid cells of its lower level (if any) it covers.
NB Statistical grid cells are squares.
EXAMPLE In a quadtree structure, some cells are associated with the four cells they are decomposed into.

A cell code.
-- Description --
This code is composed of:
1. A coordinate reference system part, represented by the word CRS, followed by the EPSG code.
2. A resolution and position part:
- If the coordinate reference system is projected, the word RES followed by the grid resolution in meters and the letter m. Then, the letter N followed by the northing value in meters, and the letter E followed by the easting value in meters too.
- If the coordinate reference system is not projected, the word RES followed by the grid resolution in degree-minute-second, followed by the word dms. Then the word LON followed by the longitude value in degree-minute-second, and word LAT followed by the latitude value in degree-minute-second.
For both cases, the given position is the position of the lower left cell corner.
NOTE: This code acts like an identifier.
