The derivation of this data set is described in detail by M.Somerville, D. Wyborn, P. N. Chopra, S. S. Rahman, D. Estrella and T. van der Meulen (1994), Hot Dry Rocks Feasibility Study, Australian Energy Research and Development Corporation Report 94/243, pp 133.

The temperature at 5 km depth has been estimated from temperature log results from 3475 boreholes for which bottom-hole temperature and temperature gradient data are available. An image has been built from these extrapolated temperature estimates using the Arc/Info createtin and tinlattice commands.

Lineage:

The lineage of this dataset is described in detail by M.Somerville, D. Wyborn, P. N. Chopra, S. S. Rahman, D. Estrella and T. van der Meulen (1994), Hot Dry Rocks Feasibility Study, Australian Energy Research and Development Corporation Report 94/243, pp 133. The image was built from extrapolated temperatures from 3475 boreholes using the Arcinfo createtin (with proximal tolerance = 0.1 angular degrees of latitude and longitude) and tinlattice (with bivariate quintic interpolation) commands.
