The Burra mine 3D model was constructed using a georeferenced version of the original hand-drafted base map, which included elevation data points surveyed during the final phase of mining. These elevation locations and associated height data were digitised from the georeferenced map into a GIS point dataset. Borehole and survey station points were captured and saved in separate point datasets. The point dataset elevation values were transferred to the base plan polylines (where spatially coinicident), and these lines were used to generate a 3D triangular irregular network (TIN). Elevation points not spatially coincident with base plan lines were added to the TIN separately. The geology dataset was draped over the TIN in a 3D visualisation environment and was output to an Adobe 3D pdf format for display in Acrobat Reader TM.
