SCHEDULE 1MINIMUM REQUIREMENTS FOR STRATEGIC NOISE MAPPING
Interpretation1
In this Schedule—
“editable” means in a format that allows (without the need for manipulation) the electronic production of—
- a
numerical data in tables, and
- b
graphical plots,
to display the information described in paragraphs 1.5, 1.6, 1.7, 2.5, 2.6 and 2.7 of Annex VI of the Directive;
- a
“grid” means a grid of vector points which are—
- c
at 10 metre by 10 metre intervals,
- d
spatially referenced to the British National Grid reference system used by the Ordnance Survey as a pair of integers to show Eastings then Northings in metres from the origin, and
- e
aligned with the 10 metre vertices of the British National Grid reference system used by the Ordnance Survey so that references finish with the number zero.
- c
