3 Introduction - 5 year research programme into 3D geological modelling completed in Standards, data formats and workflows have been established - GSI3D and GoCad have been chosen as corporate software - Systematic geological models of the UK are now core deliverable of the Survey - Development of products and delivery methods is now one of the key priorities 20 projects and more than 50 staff have contributed to the work presented here A BIG THANKS TO ALL

12 What does the customer want?. Answers! Water Industry and Environment Agency Geological cross-sections with hydrostratigraphical attribution, hydrogeological domains maps, grid export of thicknesses, tops and bases of aquifers and aquitards for groundwater flow modelling. Town Planners, Civil Engineers and Insurance Industry Maps of unstable, man made or undermined ground, subsurface maps for planning excavations, site specific geological information, sections along roads and tunnels, property models. Minerals Industry Isopachytes of resources and overburden, volume predictions, predictive boreholes, cut away functions for quarry design. The Public and Academia Standard geological maps, home buyers reports, uncovered geological maps, fence diagrams, exploded views, 3D geological animations.

15 Some conclusions Many customers are overwhelmed even with 2D geological maps. Traditionally maps had to be re-interpreted in order to answer a specific request. The current requirements of customers from a 3D geological map are hugely varied. They range from paper output, GIS export to video clips and gridded files for groundwater flow modelling. Additionally, new uses of a geological subsurface model may arise, as customers begin to understand and explore the potential of our new n product. All these points have created the potential for large inefficiency ency in delivering results from geological models to customers. A new unified delivery system had to be found
