1:50 000 Series geological maps for England & Wales are produced in landscape format, each covering an area of approximately 20km north-south and 30km east-west.
Combined sheets, special sheets and those for coastal districts may have a different coverage.
Maps are normally available in both flat and folded formats.
For some districts copies of out of print maps are available through our 'Print-on-demand' service.
These maps are printed as required (normally within 2 days) using a high resolution, high permancence digital printer: the maps are supplied in flat form only: they are indicated by '(POD)' in the list.
