Additional information

In some cases, BGS may hold multiple copies of the same map - for example if there were originally different copies held in different Survey offices, or at different locations at the same site. As a result of this, there may be multiple scans for the same map. Maps also may have had copies produced for different purposes: for example, a hand-drawn and coloured geological 'standards' (officially approved maps), dyeline masters (created for reproduction), and dyeline prints (uncoloured and hand-coloured). A considerable number of these maps were printed lithographically, mostly in monochrome (sometimes called 'lines edition'). Some were also printed in colour. In the late 1970s, conversion to the metric 1:10 000 scale was introduced and became the standard large-scale format for field mapping. Formal publishing was abandoned and replaced by dyeline or photographic processes as a method of reproduction, maps were printed on demand rather than printing and holding stocks. On completion of each sheet, it became customary to prepare a short descriptive report providing notes and local details of the geology for each map sheet area. These were issued as 'open-file' in the Survey Technical Report series. Minor, undocumented changes may have been made to some of the maps (for example, new geological boundaries or changes in the colour of a geological unit). Occasionally, copies of the original standard were made, and the changes were marked on, without changing the signed and approved standard. These copies are often called 'correction copies'. Later maps were created digitally as 'electronic masters' and 'digital deposit copies'. These differ in their marginal information. Digitally-produced maps were, for the most part, printed, hand-signed and then scanned. A very small number of maps produced later (generally post-2010) were signed digitally and a hardcopy map was never produced.

Statement

The geological maps were created by the Geological Survey from approximately the 1960s onwards. The paper maps were scanned to TIF image format at 300 dpi. JPEG2000 and PDF copies were created from the master TIF scans. Since then, further maps have been added to the collection as these have been scanned.
