Layer 08A Great Artesian Basin base of Evergreen and Marburg formations surface

Brief description

Layer 08A Base of Evergreen and Marburg formations

Surface produced for the Great Artesian Water Resource Assessment (GABWRA) by Geoscience Australia (http://www.ga.gov.au). This surface was created for 3D visualisation of the Base of Poolowanna Formation.

The surface is available in the following formats
1. GOCAD surface (.ts)
2. ESRI grid
3. ASCII grid (.grd)

Use limitations:
1. GOCAD surface requires program capable of reading GOCAD *.ts (triangulated surface) files
2. ASCII grid data requires re-interpolation by end-user resulting in minor differences to accompanying GOCAD *.ts surface.
