From watercolour to web

The British Geological Survey has been making maps across three centuries but the way these are surveyed, drawn and used has changed radically in the past 20 years with the advent of the internet era. The modern BGS field geologist and cartographer have digital technologies at their disposal which would amaze the nineteenth century surveyor. The map user can now reach beyond the traditional paper product to their computer or even their mobile phone to see instant displays of the geology and gain access to the framework of digital information that supports the geological interpretation.
