Others involved:
This research has addressed problems of integrating linear and polygonal features within a terrain model, as well as within a fully three dimensional model of sub-surface geology. A multi-resolution spatial data access scheme has been developed based on hierarchies of triangulated surfaces representing terrain and geological strata. Flexibility in access to arbitrary combinations of data at different levels of detail has been achieved, in combination with considerable savings in storage space, by means of a novel storage technique called the Implicit TIN (Triangulated Irregular Network). Modelling of complex faulted and folded geological structures is a major challenge and it is intended to pursue this aspect of this research in future using artificial intelligence techniques that may assist in knowledge-based procedures for interpolating the form of structures from sparse datasets.
