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.
