The following primary datasets were used in the construction of the Teesside 3D model:
* DTM – the BGS derived BaldEarth digital terrain model (DTM) was used as the capping surface and was resampled to give a cell resolution of 50m
* Rockhead model – this was extracted from the corporate rockhead model dataset (V5) at the start of the project (01/08/2012).
* Borehole data – Boreholes were coded by H Burke and C Horabin using the BGS Superficial Deposits Coding Scheme (Cooper et al, 2005), and content code “DU”. All coded boreholes were extracted from SOBI/BoGe using an access query to create BID/BLG files for import into GSI3D software. The Borehole Filter Tool was used to prioritise and deduplicate the borehole records using the following priority order:
