Technological advances in surveying, cartography and GIS have changed the face of geological mapping at the British Geological Survey. In the space of ten years the process has developed from a largely paper-based system to a system which is entirely digital. The SIGMA (System for Integrated Geospatial Mapping) workflow uses a suite of GIS based applications that can be used in the field on a specialised tablet PC and enables final cartographic compilation in the office. This article outlines some of the processes used to create a geological map of superficial deposits (non-bedrock geology such as glacial and floodplain deposits) from pre-fieldwork preparation to the final map or spatial data set.
