“…3D models could be particularly useful to local authorities and planners and developers of brownfield sites, who may benefit from a clearer visualisation of the spatial interaction between geological units, including their inherent properties (such as permeability), and other aspects of infrastructure, such as pipelines, cables and transport tunnels that a 3D model can clearly illustrate (Aldiss, et al, 2012).…”

Government-led regeneration schemes and policies encouraging the use of brownfield land present a challenge, particularly in coalfield areas. Coalfields have typically experienced multiple phases of development and can be susceptible to a suite of problematic ground conditions that may be rooted in the near-surface geology or result from anthropogenic activity. Such problems, related to the nature of void backfill, undermined and unstable ground and the presence of contaminated land in the near-surface, may deter investment in the very areas earmarked for redevelopment. An understanding of previous developments within coalfields is required to identify potential geological hazards, so that regeneration proposals include measures that address these issues. Public records of landfill sites, site investigations and minerals exploration, including opencast mine plans, can reveal the distribution, thickness and high-level descriptions of fill materials, although the coverage of data typically precludes a comprehensive analysis of entire cities. The best way to show the spatial distribution of fill materials is currently as a two dimensional national/regional scale dataset. Depending on the distribution of data points, however, 3D modelling can be possible, which is much more detailed and accurate. Focusing on the heavily urbanised county of West Yorkshire in northern England, the assessment of opencast coal mining on the landscape and benefits of quantifying the impact are discussed. We demonstrate how certain types of publicly available data allow a greater understanding of the interaction between human activity and natural superficial and bedrock geology. If successful, this approach can help lessen the impact of delays and increased financial costs caused by unforeseen ground conditions.

The ability to extract properties from 3D geological framework models for use in the construction of conceptual and mathematical models is seen as increasingly important, however, tools and techniques are needed to support such information flows. Developing such methodologies will maximize the opportunity for information use and re-use, this is particularly important as the true value of such assets is not always known when they are first acquired. This paper briefly describes the cultural and technical challenges associated with the application of information derived from 3D geological framework models by hydrogeological process models. We examine how these issues are being addressed and present a tool, SurfGrid, which allows a user to generate 3D grids (voxels) of parameterized data from a series of geological surfaces. The procedures and tools described offer the ability to re-use expensively created assets by providing user friendly techniques that enable multidisciplinary scientists to extrapolate property distributions from geological models.

Abstract-Modern communication technologies are changing the way we think about spatial mapping information and how we deliver it into the hands of end-users. For geoscience, the challenges are particularly interesting because of the strong three-dimensional nature and sheer richness of the underlying geological information. For several hundreds of years, the favoured method for delivering this information has been the paper map. However, as in the topographical sector, the geosciences have moved rapidly over recent years to digital platforms for effective delivery of spatial information. What we are delivering is still a map, but what it looks like and how it is carried will have changed beyond recognition for earlier surveyors. In particular, new generations of mobile tablet computers and smartphones, which can self-locate using GPS technology, and stream in spatial mapping live to the user, have all but rendered the paper map redundant in many parts of the UK and beyond. Furthermore, the interactive nature of these technologies allows two-way sharing of information, through twinned display of digital maps and live 'crowdsourced' collection of point observations. But perhaps the greatest opportunities lie in the use of augmented reality techniques to transform complex three-dimensional information into an easily digestible form for the user. The paper map made an admirable attempt to do this in the geosciences but mobile technologies and software offer the chance to at last display the information in the way it has always existed within the mind of the geological surveyor. This paper describes the informatics research and development work lead by the British Geological Survey (Natural Environment Research Council) which is taking on these challenges and opportunities, and is already beginning to deliver a new and very different generation of the geological map.
