1:50 000 Geological Maps - Scotland
The individual 1:50 000 Series geological maps for Scotland are produced in portrait format, each covering an area of approximately 30km north-south and 20km east-west.
Combined sheets, special sheets and those for coastal districts may have a different coverage.
The map grid used is based on the now-superseded Ordnance Survey One-Inch Sheet Grid for Scotland.
Maps are numbered in pairs, East and West (eg S040E and S040W) with each having its own sheet name.
Maps are normally available in both flat and folded formats.
