The resulting product is a 20 m regular pitch matrix, the elements of which (pixels) report the values of the dimensions. The coordinates are flat UTM-ED50 in the respective casting of which they belong. Matrix data is transferred in an ASCII or BINARIO format. The unit of sale is the tile, i.e. the division of the national territory, in the two mergers, into areas of dimensions 10Km x 10Km.
