is part <strong>of</strong> a much wider set <strong>of</strong> systems <strong>and</strong> work processes that together make up the<br />
cyberinfrastructure <strong>of</strong> a modern geological survey. <strong>The</strong> GSI<strong>3D</strong> s<strong>of</strong>tware is not yet designed<br />
to cope with bedrock structures in which individual stratigraphic surfaces are repeated or<br />
inverted, but the s<strong>of</strong>tware is currently being extended by BGS to encompass these more<br />
complex geological scenarios. A further challenge for BGS is to enable its <strong>3D</strong> geological<br />
models to become part <strong>of</strong> the semantic web using GML application schema like GeoSciML.<br />
<strong>The</strong> biggest benefits <strong>of</strong> widely available systematic geological models will be an enhanced<br />
public underst<strong>and</strong>ing <strong>of</strong> the subsurface in <strong>3D</strong>, <strong>and</strong> the teaching <strong>of</strong> geoscience students.<br />

1. Introduction<br />
1.1 Background<br />
Three-dimensional geological modeling has developed dramatically over the past 30 years<br />
from contouring <strong>and</strong> gridding techniques using mainframe computers through to PC based<br />
geological modeling s<strong>of</strong>tware developed mainly for the hydrocarbon <strong>and</strong> mining industry.<br />
<strong>The</strong>se tools were developed with large sums <strong>of</strong> money available in the relevant industries <strong>and</strong><br />
therefore <strong>of</strong>ten only deal with very specific geological scenarios <strong>and</strong> data types. CAD <strong>and</strong><br />
GIS tools were also customised to deal with geological environments, but this <strong>of</strong>ten led to a
