Optimised for 1:50 000 (Landranger scale), the raster tiles have approximately 2.5 m per pixel resolution which is perfect for environmental mapping, landscape planning, and regional projects.
Which areas are covered with this data set?
Full Great Britain coverage (excluding Northern Ireland).
What file formats are included?
Supplied in GeoTIFF format, with options for GeoTIFF (LZW or palette bit), standard TIFF, or BMP as needed. An accompanying world file (.tfw) is also provided
What are typical uses of 1:50 000 GeoTIFF tiles?
