4. 1 Introduction The Subsurface Viewer is an exciting new package developed by INSIGHT Geologische Softwaresysteme GmbH for the visualisation and analysis of digital geoscientific spatial models This Viewer has been developed following the popularity of INSIGHT s Geological Surveying and Investigation in 3D GSI3D software tool that BGS uses extensively for the construction of systematic near surface models Kessler and Mathers 2004 Kessler et al 2005 Kessler et al 2009 Geological Models are embedded within the Subsurface Viewer as the means of publication In this way the constructed model can be examined and analysed to produce e Models displaying the geology or other pre selected applied themes e g hydrogeological properties Geological maps at surface and uncovered User defined synthetic borehole logs User defined horizontal slices and vertical sections Visualisation of the geometry of single and combined units Please note that the models supplied with the Subsurface Viewer are encrypted and cannot be altered nor can users add additional data 2 Installation and use of the Subsurface Viewer The model and the necessary Java software and extensions will be delivered to the client on a CD ROM or via a secure FTP site The executable file will install java software onto the PC if the minimum Java Runtime is not found so administrative permissions must be set accordingly To load the Subsurface Viewer onto your comput
