Geology Digimap is also known as Geology Roam and requires you to register with the provider, EDINA, before use and then to log in with your SSO again at the homepage.
It is part of the Digimap Collection of on-line mapping and data delivery facilities and users can view maps through their web browser, save maps for printing and download the geological map data for use in a Geographic Information System (GIS) or image processing software.
You can view and print geology maps at 12 different zoom levels and use a single-click feature to identify rock types using the BGS Lexicon of Rock Units. Maps can be customised to show different themes and the transparency of the geology layers can be altered to enable easier viewing of Ordnance Survey backdrop maps.
Using current British Geological Survey map data and the Lexicon of named Rock Units the following data are available as both maps generated online and as data to download:
Oxford University libraries have a wealth of 17th to 19th century geological literature that is central to the development of the subject area, in particular as it applies to the 'English School' of Geology. Some of this literature also relates to specimens held in the Geological Collections of the University Museum of Natural History, records and images of which are available on-line. The digitization of these key books and maps and their availability on the web through the Oxford Digital Library provides a very rich, immediate resource of rare items for scholars and researchers in the history of science, geology, palaeontology, petrology, and mineralogy. Many of these items are beautifully illustrated, depicting for example fossils, rock sequences and landscapes.
