The Geology Maps facility in Geology Digimap has been greatly enhanced by upgrading the technology. The maps now use a transparency technique to represent rock types in colour, rather than hatching. The result has been much clearer maps, more closely matching their paper counterparts printed by the British Geological Survey. It also makes it easier to see the underlying context mapping, as well as identifying which rock types overlay which. Below are some examples of the new colour scheme.
Old and new versions, clearly labelled
The previous version of Geology Maps is still available for those who have become accustomed to it or have created training courses based upon it. This version is clearly labelled "old". It will be withdrawn at the start of the next academic year (2008/9) when we hope everyone will be enjoying the benefits of the new maps.
